New Recyclable & Biodegradable Building Material
Based On Plant Starches Developed  (https://renewablerevolution.createaforum.com/proxy.php?request=http%3A%2F%2Fwww.pic4ever.com%2Fimages%2F19.gif&hash=3f9f2fc2285bc756137e21463bc2a4c420b15ac3)



A novel new form of medium-density fibreboard (MDF) that’s both biodegradable and recyclable can be created by substituting a resin derived from common plant starches, such as those in potatoes, for the urea and formaldehyde that are typically used in MDF.

The new creation is thanks to research from the University of Leicester. The researchers behind the new resin think that the development of the new recyclable MDF will help to reduce the enormous waste that typically accompanies the use of MDF — as it stands now, most of the huge quantities of MDF produced annually in the UK ends up in the incinerator or the landfill within a year or two, as it cannot be recycled.

Given that most MDF in the UK is used primarily for short-term applications in the retail sector, the development of an MDF-substitute that can actually be recycled could do a great deal to help reduce the quantity of waste produced by the retail sector, according to the researchers.
The University of Leicester provides more info:

MDF is made by breaking down bits of wood into wood fibres, which are then pressurized and stuck together with resin and wax. The resin is currently composed of urea and formaldehyde (UF), the use of which is restricted due to health concerns. Professor Abbott’s new resin means that the use of UF is avoided and therefore so too are the associated concerns.

With the aid of colleagues at the Biocomposites Centre, Bangor University and the Leicestershire-based retail design company Sheridan and Co, his team have produced starch-based boards which have been made into retail display units. Professor Abbott’s new material is easier to manufacture and easier to work with than current MDF boards.


The experimental part of the research was led by Dr Will Wise, who stated: “It has been a technological challenge to develop material with the correct properties, but it is a great thrill to see the finished boards which look identical to the MDF which is so commonly used.”

The new material is easier to manufacture than existing MDF as the components are easily pre-mixed and only set on the application of heat and pressure; end user feedback suggests it is also easier to work with than currently available MDF boards.

The researchers recently won the Royal Society Brian Mercer Award for Innovation for the new recyclable MDF, after receiving the award, Professor Abbott stated: “The Brian Mercer Award is fundamental in enabling us to take this project forward to the next stage; it means we can now scale up our process from laboratory to the full scale manufacture of a product that I hope will revolutionize industries dependent on MDF and provide them with a more environmentally-friendly alternative.”
In total, the award will provide the researchers with about £172,347 — nearly all of which will be used “to create a supply chain to create prototypes for the point-of-sale market.”

The research team is also currently in the process of developing new fillers for plastics based on orange and banana peels and eggshells.

Title: Dandelions Into Rubber — Making Rubber From Dandelion Juice

Dandelions Into Rubber — Making Rubber From Dandelion Juice


The first-ever modern pilot system for the extraction of large quantities of tire rubber from dandelions is currently in the process of being built by researchers at the Fraunhofer Institute for Molecular Biology and Applied Ecology IME, in cooperation with Continental. The pilot project is possible thanks to a number of important improvements to cultivation and production engineering over the past few years.

It’s been known for quite a long time that dandelions, in addition to being an excellent source of nutrition, and to possessing notable medicinal qualities, are an excellent source of latex rubber. The researchers think that the new pilot project is an important step towards the goal of a rubber-independent Europe — potentially, in the future, no longer having to rely on imports from tropical countries for the important resource.

Fraunhofer-Gesellschaft provides more:

The joint project officially started at the beginning of October. The goal is to develop the production process over the next five years so that Continental can manufacture tires made from dandelion rubber. This is why molecular biologists at IME and the research department of the automotive supplier built a pilot facility in Münster that is capable of producing natural rubber by the ton.

At the same time, they cultivate several hectares of a dandelion variety which is particularly rich in rubber. To optimize the raw material content and the properties of the blossom, the researchers concurrently grew new varieties with a higher proportion of rubber and biomass yield.

The first prototype test tires made with blends from dandelion-rubber are scheduled to be tested on public roads over the next few years. The natural product obtained in this manner exhibited the same quality as the conventional rubber from rubber trees that has been imported from subtropical countries and used in tire production. However unlike the conventional rubber, it could be harvested more cost-effectively, better cultivated and grown in Germany as a sustainable raw material — even on land areas not previously suited for agricultural crops.

“Through the most modern cultivation methods and optimization of systems technology, we have succeeded in manufacturing high-grade natural rubber from dandelions — in the laboratory. The time is now right to move this technology from the pilot project-scale to the industrial scale. We have found an expert partner in Continental, with whom we now want to create tires that are ready for production,” states Professor Dr Rainer Fischer, head of institute at IME in Aachen.

“We are investing in this highly promising materials development and production project because we are certain that in this way we can further improve our tire production over the long term,” explains Nikolai Setzer, the Continental managing director who is responsible for the tires division. “It’s because the rubber extraction from the dandelion root is markedly less affected by weather than the rubber obtained from the rubber tree  :o.

Based on its agricultural modesty, it holds entirely new potential — especially for cropland that is lying fallow today. Since we can grow it in much closer proximity to our production sites, we can further reduce both the environmental impact as well as our logistics costs by a substantial margin. This development project impressively demonstrates that, with regard to material development, we have not reached the end of our potential.” (https://renewablerevolution.createaforum.com/proxy.php?request=http%3A%2F%2Fwww.pic4ever.com%2Fimages%2F128fs318181.gif&hash=eff6d5f3831782966c2ff2081f07bf7fc5b22a6b)

“With this new technology, we can achieve a sustainable edge for the German automotive market. On the one hand, it makes the domestic economy less dependent on the importing of raw materials.

On the other hand, it reduces the transportation routes, and thus improves the CO2 balance,” notes Dr Ing Reimund Neugebauer, President of the Fraunhofer-Gesellschaft.

In the years 2000 to 2008, worldwide consumption of biodegradable plastics based on starch, sugar, and cellulose – so far the three most important raw materials – has increased by 600%.[32] The NNFCC predicted global annual capacity would grow more than six-fold to 2.1 million tonnes by 2013.[30] BCC Research forecasts the global market for biodegradable polymers to grow at a compound average growth rate of more than 17 percent through 2012. Even so, bioplastics will encompass a small niche of the overall plastic market, which is forecast to reach 500 billion pounds (220 million tonnes) globally by 2010.[33]
http://en.wikipedia.org/wiki/Bioplastic (http://en.wikipedia.org/wiki/Bioplastic)

Agelbert NOTE:The "NICHE" that bioplastics are occupying will grow to destroy the fossil fuel based plastics plastic poisons simply because bioplastics are sustainable AND cheaper now.


Cost

At one time bioplastics were too expensive for consideration as a replacement for petroleum-based plastics.The lower temperatures needed to process bioplastics and the more stable supply of biomass combined with the increasing cost of crude oil make bioplastics price [34] more competitive with regular plastics.(https://renewablerevolution.createaforum.com/proxy.php?request=http%3A%2F%2Fwww.pic4ever.com%2Fimages%2F19.gif&hash=3f9f2fc2285bc756137e21463bc2a4c420b15ac3)
http://en.wikipedia.org/wiki/Bioplastic (http://en.wikipedia.org/wiki/Bioplastic)


ApplicationsBiodegradable bioplastics are used for disposable items, such as packaging and catering items (crockery, cutlery, pots, bowls, straws). They are also often used for bags, trays, containers for fruit, vegetables, eggs and meat, bottles for soft drinks and dairy products, and blister foils for fruit and vegetables.

Nondisposable applications include mobile phone casings, carpet fibres, and car interiors, fuel line and plastic pipe applications, and new electroactive bioplastics are being developed that can be used to carry electrical current.[5] In these areas, the goal is not biodegradability, but to create items from sustainable resources.

Medical implants made of PLA, which dissolve in the body, save patients a second operation. Compostable mulch films for agriculture, already often produced from starch polymers, do not have to be collected after use and can be left on the fields.[6]

Bioplastic Car Parts

In constructing the Prius, Toyota used a new range of plant-derived ecological bioplastics, made out of cellulose derived from wood or grass instead of petroleum. The two principal crops used are kenaf and ramie. Kenaf is a member of the hibiscus family, a relative to cotton and okra; ramie, commonly known as China grass, is a member of the nettle family and one of the strongest natural fibres, with a density and absorbency comparable to flax.
Toyota says this is a particularly timely breakthrough for plant-based eco-plastics because 2009 is the United Nations’ International Year of Natural Fibres, which spotlights kenaf and ramie among others.[56]

Polylactic acid (PLA) is a transparent plastic produced from corn[12] or dextrose. It not only resembles conventional petrochemical-based mass plastics (like PET, PS or PE) in its characteristics, but it can also be processed on standard equipment that already exists for the production of some conventional plastics. PLA and PLA blends generally come in the form of granulates with various properties, and are used in the plastic processing industry for the production of films, fibers, plastic containers, cups and bottles.

Biopolymer BHP can replace petroplastic polypropylene

Poly-3-hydroxybutyrate (PHB)


The biopolymer poly-3-hydroxybutyrate (PHB) is a polyester produced by certain bacteria processing glucose, corn starch[13] or wastewater.[14] Its characteristics are similar to those of the petroplastic polypropylene. The South American sugar industry, for example, has decided to expand PHB production to an industrial scale. PHB is distinguished primarily by its physical characteristics. It produces transparent film at a melting point higher than 130 degrees Celsius, and is biodegradable without residue.

Polyhydroxyalkanoates (PHA)

Polyhydroxyalkanoates (PHA) are linear polyesters produced in nature by bacterial fermentation of sugar or lipids. They are produced by the bacteria to store carbon and energy. In industrial production, the polyester is extracted and purified from the bacteria by optimizing the conditions for the fermentation of sugar. More than 150 different monomers can be combined within this family to give materials with extremely different properties. PHA is more ductile and less elastic than other plastics, and it is also biodegradable. These plastics are being widely used in the medical industry.

http://en.wikipedia.org/wiki/Bioplastic (http://en.wikipedia.org/wiki/Bioplastic)

How to tell if plastic was made from fossil fuels or plants: Fossil fuel derived plastic has NO carbon-14!

Biobased – ASTM D6866

The ASTM D6866 method has been developed to certify the biologically derived content of bioplastics. Cosmic rays colliding with the atmosphere mean that some of the carbon is the radioactive isotope carbon-14. CO2 from the atmosphere is used by plants in photosynthesis, so new plant material will contain both carbon-14 and carbon-12. Under the right conditions, and over geological timescales, the remains of living organisms can be transformed into fossil fuels. After ~100,000 years all the carbon-14 present in the original organic material will have undergone radioactive decay leaving only carbon-12. A product made from biomass will have a relatively high level of carbon-14, while a product made from petrochemicals will have no carbon-14. The percentage of renewable carbon in a material (solid or liquid) can be measured with an accelerator mass spectrometer.[41][42]

http://en.wikipedia.org/wiki/Bioplastic (http://en.wikipedia.org/wiki/Bioplastic)

Plastic made from plants is NOT a guarantee of biodegradability

There is an important difference between biodegradability and biobased content. A bioplastic such as high density polyethylene (HDPE)[43] can be 100% biobased (i.e. contain 100% renewable carbon), yet be non-biodegradable. These bioplastics such as HDPE nonetheless play an important role in greenhouse gas abatement, particularly when they are combusted for energy production. The biobased component of these bioplastics is considered carbon-neutral since their origin is from biomass.

http://en.wikipedia.org/wiki/Bioplastic (http://en.wikipedia.org/wiki/Bioplastic)

Agelbert NOTE:[/b] As I've said before, products from corn for plastics or biofuel are a bad deal. At the end of the wikipeda bioplastics article, a "study" from scientists in 2010 cautions against corn based bioplastics because they are so polluting from the pesticide and CO2 releasing properties  (https://renewablerevolution.createaforum.com/proxy.php?request=http%3A%2F%2Fwww.pic4ever.com%2Fimages%2F2rzukw3.gif&hash=f0487b8f0d488ab1126ce5e031b11ea3d74b1cc2)(as if petrochemical fuels and plastics weren't measurably MORE polluting... ??? ).

Sure. That's why BIG OIL wants us to keep using that corn for ethanol and bioplastics!  ;) It's never going to be competitive! Corn uses pesticides and plowing. The plastics made from the corn starch will have pesticide residue. Growing corn is an excellent way to ruin top soil and is second only to fossil fuels (because it uses so much of them) in biosphere damage. :P  >:(

This is stupid when, duckweed, hemp, sugar cane, switchgrass, Kenaf , a member of the hibiscus family, a relative to cotton and okra and  Ramie, commonly known as China grass, a member of the nettle family and one of the strongest natural fibres, with a density and absorbency comparable to flax are all available, easier to grow WITHOUT PESTICIDES and provide a much higher EROEI.

Mature trees soak up more CO2 than younger ones, a study shows, overturning a bit of botanical dogma.  :o

By Bob Grant | January 20, 2014

It turns out that as a slew of tree species age, they grow faster and gobble up more carbon dioxide than when they were younger, according to a study published last week (January 15) in Nature.

The findings, which involved decades of data taken from 673,046 trees in more than 400 tropical and temperate tree species around the globe, contradict a long-standing assumption that tree growth slows as the plants age. “The trees that are adding the most mass are the biggest ones, and that holds pretty much everywhere on Earth that we looked,” Nathan Stephenson, a US Geological Survey ecologist and first author of the study, told Nature. “Trees have the equivalent of an adolescent growth spurt, but it just keeps going.”


The results have important implications for conservation and forestry practices. “Not only do [older trees] hold a lot of carbon, but they’re adding carbon at a tremendous rate," Stephenson told NPR. “And that’s going to be really important to understand when we’re trying to predict how the forests are going to change in the future—in the face of a changing climate or other environmental changes.”

Agelbert NOTE: This is another reason why old growth trees should NOT be used for firewood or any other kind of biomass. Grasses like Hemp and angiosperms like duckweed and Azolla can provide all the textiles and woody furnace pellets we need. Leave the forests alone!

US Navy Says Biofuels Are New Normal  ;D

SustainableBusiness.com News

After experimenting with biofuels for several years, the US Navy announced its use will now be standard practice, incorporated into all solicitations for jet engine and marine diesel fuels.

"The Navy has a long history of energy innovation. From sail to coal, coal to oil, and then to nuclear, the Navy's led the way. We see biofuel as that next energy innovation, and we're taking action," says Tom Hicks, acting undersecretary of the Navy."

 Under "Farm-to-Fleet," biofuel blends - such as waste oils from cooking grease and algae - will be purchased in all Department of Defense (DOD) domestic solicitations.

 "This effort marks the start of the ‘new normal,' where drop-in biofuels will be fully integrated with our regular fuel operations, says Secretary of the Navy Ray Mabus.

Navy

The initiative began in 2010, when President Obama challenged the Departments of Agriculture, Energy and Navy to collaborate on speeding development of domestic, competitively-priced "drop-in" diesel and jet fuel substitutes.

You may remember that Republicans were up in arms when they heard the Navy used $15 per gallon biofuels for its Great Green Fleet demonstration. Just a few years later, DOD expects to buy the fuels at competitive prices - less than $4 per gallon by 2016. The program starts with a bulk fuels solicitation this year, with deliveries in mid-2015.

"We absolutely have to have - particularly in this constrained budget environment - a stably priced, domestically produced alternative to fossil fuels that do spike just on world crises," explains Mabus.  "Every time the price of oil goes up $1 per barrel, it costs the Navy Department an extra $30 million."


They are starting with blends of 10% and growing to 50% with conventional fuels over the next few years. Starting small will help biofuel companies get to the volumes and price points they need. 

To meet its goal of cutting petroleum use 50% by 2020, the Navy also plans to have its own biorefineries, at no cost to taxpayers. Its also leading on microgrids and, of course, solar.

 Another promising technology converts seawater into liquid fuel ( http://renewablerevolution.createaforum.com/renewables/hydcrocarbons-from-seawater-(carbon-neutral)-for-less-than-$3-a-gallon!/msg904/#msg904 ) , while removing carbon at the same time. The Navy recently invested $30 million in Hawaii's Energy Accelerator to speed technologies to market.

I LOVE DUCKWEED! (https://renewablerevolution.createaforum.com/proxy.php?request=http%3A%2F%2Fwww.pic4ever.com%2Fimages%2Fearthhug.gif&hash=3abcf70466f34337f2d702ebd9e02c650d5c4c20)

Pond-dwelling powerhouse’s genome points to its biofuel potential



Duckweed is a tiny floating plant that’s been known to drive people daffy. It’s one of the smallest and fastest-growing flowering plants   ;D that often becomes a hard-to-control weed in ponds and small lakes. But it’s also been exploited to clean contaminated water and as a source to produce pharmaceuticals. Now, the genome of Greater Duckweed (Spirodela polyrhiza) has given this miniscule plant’s potential as a biofuel source a big boost. In a paper published February 19, 2014 in the journal Nature Communications, researchers from Rutgers University, the Department of Energy Joint Genome Institute and several other facilities detailed the complete genome of S. polyrhiza and analyzed it in comparison to several other plants, including rice and tomatoes.

Duckweed, a small, common plant that grows in ponds and stagnant waters, is an ideal candidate as a biofuel raw material.  (https://renewablerevolution.createaforum.com/proxy.php?request=http%3A%2F%2Fwww.pic4ever.com%2Fimages%2F128fs318181.gif&hash=eff6d5f3831782966c2ff2081f07bf7fc5b22a6b) ;D Photo (at link) by Texx Smith, via flickr

 
Simple and primitive, a duckweed plant consists of a single small kidney-shaped leaf about the size of a pencil-top eraser that floats on the surface of the water with a few thin roots underwater. It grows in almost all geographic areas, at nearly any altitude. Although it’s a flowering plant, it only rarely forms small indistinct flowers on the underside of its floating leaves. Most of the time, it reproduces by budding off small leaves that are clones of the parent leaf. It often forms thick mats on the edges of ponds, quiet inlets of lakes and in marshes. It’s among the fastest growing plants, able to double its population in a couple of days under ideal conditions. (https://renewablerevolution.createaforum.com/proxy.php?request=http%3A%2F%2Fwww.pic4ever.com%2Fimages%2F170fs799081.gif&hash=ec7f929a28b215e9c00ec270a26b830d596920b2)

These and other properties make it an ideal candidate as a biofuel feedstock – a raw source for biofuel production. For example, unlike plants on land, duckweeds don’t need to hold themselves upright or transport water from distant roots to their leaves, so they’re a relatively soft and pliable plant, containing tiny amounts of woody material such as lignin and cellulose. Removing these woody materials from feedstock has been a major challenge in biofuel production. Also, although they are small enough to grow in many environments, unlike biofuel-producing microbes, duckweed plants are large enough to harvest easily. ;D

S. polyrhiza turns out to have one of the smallest known plant genomes, at about 158 million base pairs and fewer than 20,000 protein-encoding genes. That’s 27 percent fewer than Arabidopsis thaliana – which, until recently, was believed to be the smallest plant genome – and nearly half as many as rice plants.

Spirodela is one of the smallest plants in the world. Here (at the link)it is displayed with other comparable plants.

 
“The most surprising find was insight into the molecular basis for genes involved in maturation – a forever-young lifestyle,” said senior author Joachim Messing, director of the Waksman Institute of Microbiology at Rutgers University.

S. polyrhiza leaves resemble cotyledons, embryonic leaves inside plant seeds that become the first leaves after germination. But where other plants develop other kinds of leaves as they mature, S. polyrhiza’s never progresses and continuously produces cotyledon leaves. This prolonging of juvenile traits is called “neoteny.” S. polyrhiza had fewer genes to promote and more genes to repress the switch from juvenile to mature growth.

“Because of the reduction in neoteny, there is an arrest in development and differentiation of organs. So this arrest allowed us to uncover regulatory networks that are required for differentiation and development,” Messing said.

Also intriguing to the research team were which genes were preserved over time and which were not. Many of the genes responsible for cellulose and lignin production in land dwelling plants were missing, (https://renewablerevolution.createaforum.com/proxy.php?request=http%3A%2F%2Fwww.clker.com%2Fcliparts%2Fc%2F8%2Ff%2F8%2F11949865511933397169thumbs_up_nathan_eady_01.svg.hi.png&hash=599691109af22b33f1d59dd61eb97448a9427020)  and there were fewer copies of those that were present. Genes for another compound related to cell walls called “expansins” which are involved with cell wall and root growth were also reduced.

Genes for starch production, on the other hand, were retained and are probably used for creating starch-filled turions, specialized buds produced by aquatic plants for overwintering, enabling them sink to the bottom of ponds and revive in warmer weather. Moreover, despite the reduced number of total genes, S. polyrhiza has more copies of genes for enzymes involved in nitrogen absorption and metabolism than in other plants. This is probably linked to the plant’s ability to utilize excess nitrogen in contaminated waters. (https://renewablerevolution.createaforum.com/proxy.php?request=http%3A%2F%2Fwww.clker.com%2Fcliparts%2Fc%2F8%2Ff%2F8%2F11949865511933397169thumbs_up_nathan_eady_01.svg.hi.png&hash=599691109af22b33f1d59dd61eb97448a9427020)


A thorough understanding of the genome and cellular mechanisms of S. polyrhiza could greatly enhance current efforts to recruit duckweed as a biofuel source. Messing estimates that duckweed will be a viable biofuel source within the next five years and points to Ceres Energy Group in New Jersey, which is already producing electricity from duckweed. (https://renewablerevolution.createaforum.com/proxy.php?request=http%3A%2F%2Fwww.pic4ever.com%2Fimages%2F19.gif&hash=3f9f2fc2285bc756137e21463bc2a4c420b15ac3) Understanding which genes produce which traits will allow researchers to create new varieties of duckweed with enhanced biofuel traits, such as increased reduction of cellulose or increased starch or even higher lipid production. Starch can be directly used as a biofuel source and it can be converted to ethanol, the way corn is currently converted to ethanol fuel, but oils would have greater energy than ethanol.

Duckweed is a relatively simple plant with fronds that float on the surface of the water and roots that extend into the water. In the flask on the left, you can see the dormant phase, turions, that have dropped to the bottom. Photo (at link) by Wenquin Wang
 
“Classical breeding or genetics does not apply here because of its clonal propagation and rare flowering, but these organisms can be transformed with DNA,” Messing said. “Therefore, new variants can be created with modified pathways for industrial applications. These variants would be an enhancement over what can be done now.”

This genome was sequenced as part of a DOE Office of Science JGI Community Science Program (CSP) project (formerly the Community Sequencing Program). It exemplifies the collaborative approach and innovative projects that the CSP enables among researchers. Messing pointed to the study’s advances over previous research.

“The sequencing of this genome opens new frontiers in the molecular biology of aquatic plants,” said Messing. “This publication represents the single largest advance in this field and a new milestone in plant molecular biology and evolution, as previous studies were either classical botany or biochemistry of photosynthesis. The placement of the Spirodela genome as a basal monocot species will serve as a new reference for all flowering plants.”

Title: Barnacle-Repellant Paint Developed To Reduce Shipping Costs
Post by: AGelbert on May 02, 2014, 02:52:01 pm
Barnacle-Repellant Paint Developed To Reduce Shipping Costs


A new type of barnacle-repellant paint — based around compounds derived from the Maytenus tree — has been devised by an international group of researchers.


While that, at first, may not sound like something that is that important, the reality is that the drag created by barnacles (or many other types of hitch hikers) on ship hulls contributes relatively significantly to the operating costs of shipping companies. Eliminating this issue could help to improve shipping speeds (to a degree) as well as — as previously stated — reducing costs.

The press release explains the issue and the new work:

By increasing water resistance, they can bump a ship’s fuel use by as much as 40%, which costs money, adds to pollution and depletes resources. These marine hitchhikers also can cause environmental problems by invading new parts of the globe and competing with native animals and plants. To keep hulls clean, some shipping companies have turned to special coatings. The problem is these coatings can permanently harm sea life. So the team sought an ocean-friendlier option from a sustainable source.

They turned to Maytenus trees, which are found worldwide. The plants’ root bark contains compounds that are similar to defensive agents produced by bottom-dwelling ocean creatures. In the lab, the scientists found that the compounds repel barnacles, but generally don’t cause long-term damage. They also added the compounds to paint, which they applied to tiles and field-tested in the sea. The new coatings effectively stopped algae, tube worms and other creatures from latching on.  (https://renewablerevolution.createaforum.com/proxy.php?request=http%3A%2F%2Fwww.clker.com%2Fcliparts%2Fc%2F8%2Ff%2F8%2F11949865511933397169thumbs_up_nathan_eady_01.svg.hi.png&hash=599691109af22b33f1d59dd61eb97448a9427020)

Interesting work. Of course there are certainly other ways to improve the energy efficiency of cargo ships, such as through the use of simple, good energy-efficient design, or through the use of rather more exotic seeming solutions, such as the those utilized by the Vindskip.

Or you could also always largely circumvent the issue of shipping fuel costs/pollution simply by tapping the power of the wind, or of the sun. While it’s easy to scoff at the notion of returning to wind-driven cargo shipping, the reality is that it is extremely energy efficient, and not even necessarily slower.  (https://renewablerevolution.createaforum.com/proxy.php?request=http%3A%2F%2Fwww.clker.com%2Fcliparts%2Fc%2F8%2Ff%2F8%2F11949865511933397169thumbs_up_nathan_eady_01.svg.hi.png&hash=599691109af22b33f1d59dd61eb97448a9427020)


The new research was detailed in a paper just published in the ACS journal Industrial & Engineering Chemistry Research.

Title: Back to using biomaterials like hemp so that we have a future as a species.

Hemp is having its moment. Meet the miracle plant’s biggest champion

By Amber Cortes

(https://renewablerevolution.createaforum.com/proxy.php?request=http%3A%2F%2Fupload.wikimedia.org%2Fwikipedia%2Fcommons%2Fe%2Fe4%2FLa_Roche_Jagu_chanvre_1.JPG&hash=87a8e811d3d61e80bd15ef90129d7136289d217b)
We’ve heard about the promise of hemp before: Its fibers are stronger than steel. Its seeds make for antioxidant-loaded superfood for you and your chickens. It can compete with fossil fuel as a viable alternative energy source. But ever since the Marijuana Tax Act of 1937, the U.S. has skunked hemp’s potential.  >:(

Now, Mary Jane’s younger cousin  ;D is having a moment.
Included in the recent farm bill is an amendment that allows research of the plant at colleges and universities. And more states have taken up the charge recently. Hawaii just passed an industrial hemp bill for research purposes. Both New York and Illinois are introducing similar legislation, and Missouri just passed a bill (now heading to the governor’s desk) allowing hemp extract to be used to treat epileptic seizures. And of the two states where cannabis is legalized, it’s already growing in Colorado.

Enter Doug Fine, author of the new book Hemp Bound and one of the miracle plant’s biggest cheerleaders. He’s met hemp farmers and researchers, checked out a hemp house in Canada, and even rode in a hemp-powered limo, all to prove that the plant is the next big thing for a sustainable future. He sat down with Grist to talk about why he believes hemp holds the key to “a food and energy revolution” that will also become a vital part of climate change mitigation.

Q. It seems like a very promising time for hemp! Now that research is allowed, what hemp possibilities are you most excited about?


A. It’s all coming together so rapidly. It’s such a magical time. When I went to research Hemp Bound I had no idea that the farm bill was going to include a hemp provision. I just knew that hemp was really important for the future of energy. That’s what I think is the most exciting thing about hemp – its potential for energy, its massive biomass that can be used to replace fossil fuels. While researching the book I found some very forward-thinking, sustainable farmers who said the cellulose stalks of hemp have big energy potential. So I wanted to connect the dots and see if there really was potential for hemp as a fossil fuel application. And it turns out there is.

Q. How does hemp work as an alternative energy source? And is it truly a feasible replacement for fossil fuels?


A. Individual farms can produce energy from their biomass waste and sell it to their regional grid. There are basically small power plants that use biomass, and the carbon exchange is all on the sustainability side of the ledger. The town of Feldheim in Germany turned one of Europe’s highest unemployment rates into zero unemployment by building a regional utility that put people to work collecting and using their farm waste in this kind of process. We can do this with hemp.
Santa Fe, N.M., actually had a similar plan for their whole utility system. It was scalable in size, affordable, carbon friendly, and community-owned, and the only reason it didn’t happen is that fracking kind of took the wind out of the sails of this project. So there are plans in place about how to do this in the U.S. But it’s not like old-school utilities are going to be happy to just lay down and say, “Sure, hemp farmers and communities, create your own utilities, bye, thanks, it was nice serving you.”

Q. You claim that hemp can potentially bring in “even more taxable revenue into the economy than its smokable relative.” How would that work?


A. Hemp-minded communities can do three things: invest in profitable seed oil presses, create textiles or fiber of some kind from it, and use products like hempcrete for building – and still have this biomass left over, this cellulose that we can use to create regional energy grids out of hemp.
The element that’s still coming together that we couldn’t really have predicted are these incredibly high prices that Canadian farmers are getting for their hemp-seed oil. They are making $300 per acre on it, 10 times what they make on GMO corn. And that is why hemp is going to end up being planted here. The demand curve for hemp as a super food is just happening now. Mainstream society is realizing how beneficial this is.

Q. So now that hemp is going mainstream, what would stop the cotton, synthetics, and paper industries from trying to oppose it?

A. I think it’s too late to fight it. The bipartisan cooperation on this issue almost makes you understand why the Rastafarians call the cannabis plant the “healing of the nation.” It’s getting unbelievably strange bedfellows together. There are Kentucky Republicans on the horn with the DEA saying let our farmers plant this, unbelievable stuff. The concern that some people have is not so much opposition from Big Ag but co-option. As long as there’s non-GMO hemp, I’m fine with there being millions of acres of hemp cultivated by everyone.

Q. You also mention in your book that hemp has some very practical uses for farmers. Can you talk about some of them?


A. An old-timer Nebraska rancher lady told me that her daddy used to plant hemp along the irrigation ditches in the spring. No matter how much flooding there was, it built this incredible root system that culled water and was erosion control and flood control. And then of course it’s also a high-protein snack for the cows and the fowl.

Hemp also filters toxins; it’s been used around Chernobyl to release radiation from the soil. The water demands are relatively low: One of Colorado’s first commercial hemp farmers, a very conservative farmer in Eastern Colorado struggling with drought and monoculture-damaged soil, found that planting hemp is using half the water than the previous wheat crop was.

Q. What about some industrial uses of hemp?

A. I saw an entire body of a tractor made out of a bio-composite of hemp fiber.  It’s stronger than petroleum-based plastic and lighter, not to mention easily replicable – all the dangers and the horrors of plastic potentially removed. (https://renewablerevolution.createaforum.com/proxy.php?request=http%3A%2F%2Fwww.freesmileys.org%2Femoticons%2Femoticon-object-106.gif&hash=f996659d18df7f3b445e6135e884397ac91f25b1) I mean, you know, thanks petroleum, it was a great century,  ;) you guys made a lot of things happen with plastics.

 Sam Boykin,  June 17, 2014 

While Charlotte, N.C., is perhaps best known as a financial center, with big institutions like Bank of America and Wells Fargo dominating the skyline, the area is also a major energy hub. The region is home to more than 260 companies and nearly 28,000 workers that are tied directly to the energy sector, including Charlotte-based Duke Energy. Moreover, the region is developing a growing number of clean energy initiatives, and the state has implemented legislature that requires investor-owned utilities to generate 12.5 percent of their retail sales from renewable energy by 2021.


That’s the message that the Charlotte Regional Partnership (CRP), a nonprofit economic development organization, brings with it on mission trips, including one earlier this year to Tokyo. In its efforts to tap into Japan’s growing clean energy industry, the CRP highlighted several local programs during a presentation at the U.S. Embassy.

One such program is the Catawba County Regional EcoComplex and Resource Recovery Facility. The 805-acre site has multiple components that are designed to convert byproducts and waste materials into renewable sources of energy, which are then fed to the power grid.

About 500 tons of county waste is trucked daily into the facility’s landfill. The garbage is burned inside internal combustible engines, which turn three 1-MW generators. This electricity is then sold to the power company, and the profits are used to fund other EcoComplex projects.

This includes the Biodiesel Research Facility, which harnesses heat emitted from the landfill generators. The heat breaks down seeds from locally grown feedstock crops like sunflowers and canola, converting them to biodiesel. The facility produces about 100,000 gallons of biodiesel a year, which is used in county vehicles such as dump trucks, bulldozers and excavators.

Barry Edwards, director of Catawba County’s Utilities and Engineering, says the ultimate goal is to recover all useable products and by-products from local private and public partners and use these waste products either as a source of energy or as a raw material for the production of products such as pallets or lumber. “The EcoComplex makes one industry’s output stream another industry’s input stream,” Edwards says. “It brings to life the old saying that ‘one man’s trash is another man’s treasure.’"

While the EcoComplex strives to convert waste materials into renewable energy sources, the nonprofit Envision Charlotte has implemented a program designed to reduce energy usage in the city’s urban core.

Amy Aussieker, Envision Charlotte’s executive director, explains that Smart Energy Now is a first-of-its-kind public-private initiative that uses technology to change the way people think about and use energy. The project, which is a collaborative effort between Charlotte Center City Partners, the city, county, Duke Energy, and some of the largest companies in uptown Charlotte, was announced during the Clinton initiative in Oct. 2010. About a year later special interactive kiosks and monitors were installed in 61 participating uptown buildings — totaling about 21 million square feet — that provide real-time data and graphic displays about each building’s energy consumption. “You can’t manage what you can’t measure,” says Aussieker.

The kiosks, which are sort of like giant iPads, also provide simple changes people can make to conserve energy, such as using more natural daylight in the office, setting back the thermostat when a building is unoccupied, and regularly maintaining a building’s equipment to ensure it is functioning efficiently.

Envision Charlotte announced in May its project reduced the use of electricity by 8.4 percent over its first three years. The hope is that the program will spur sustainable behaviors in order to reduce energy consumption by 20 percent over five years at an estimated savings of $16 million.

E4 Carolinas is another clean energy initiative. A consortium of energy and engineering firms, government agencies, economic development groups and educators created E4 in response to the region’s growing energy consumption. The nonprofit’s mission is to nurture workforce development and technology innovations in order to foster efficient and environmentally sensitive energy clusters. 

The collaborative effort includes a variety of companies, including Charlotte-based Calor Energy Consulting, which helps everyone from property developers to nonprofits select the best renewable energy options. Through a technical analysis, Calor determines if it’s economically feasible for a company to install a system, such as solar and wind. If so, it also assists clients with issues like seeking tax and equity investors as well as selecting the best EPC (Engineering, Procurement, Construction) for the project.

The consultant has spearheaded many projects, such as helping Charlotte’s Levine Museum of the New South obtain a key grant from Duke Energy—using key metrics like energy use, recycling programs and employee commuting—to upgrade its lighting and HVAC to meet sustainability goals. The changes have reduced the history museum’s consumption of power and gas by as much as 30 percent annually. The consultant also helped create an innovative financing plan to attract private investment in order to install a 10 KW PV solar system on the roof of Friendship Trays. The project helped the “meals-on-wheels” program save on utility bills and establish cash flow though renewable energy credit sales and tax credits. 

Another E4 Carolina partner, 02energies, develops large-scale, ground-mounted solar power plants in the Southeast, creating work and educational opportunities while enhancing sustainability. Some notable projects include Avery Solar, in which a 1 megawatt, six-acre solar farm was built at Henderson Farms, a Christmas tree farm in North Carolina. Each year, the solar farm generates 1,161 MWh of electricity during times of peak demand. The company also installed a 1.2-MW solar power plant at Mount Airy, the childhood home of actor Andy Griffith and a popular tourist attraction. The six-acre site generates electricity into the Duke Energy grid and provides power to hundreds of homes and small businesses.

The Charlotte region is one of the fastest-growing metro areas in the country. Its population increased 1.8 percent, climbing to 2.3 million, between July 2012 and July 2013. Moreover, the region is expected to see an influx of more than 1.8 million people over the next 40 years — increasing the current population by more than half. This makes CRP’s economic development efforts and initiatives like EcoComplex, Envision Charlotte and E4 Carolinas all the more important as a way to both safeguard the environment and strengthen the region’s position in the global marketplace.

When paper is recycled, its fibers become weakened, and virgin wood pulp must be added to strengthen it. Recycled paper can be used as many as six times, so it saves on the amount of virgin wood pulp that must be processed. Recycled paper production also saves 80% on water and generates about 95% less air pollution.

The Ugly Duckling: Can Duckweed Find Its Way to Bioenergy Commercialization?   (https://renewablerevolution.createaforum.com/proxy.php?request=http%3A%2F%2Fwww.pic4ever.com%2Fimages%2F128fs318181.gif&hash=eff6d5f3831782966c2ff2081f07bf7fc5b22a6b)

 Bruce Dorminey, Correspondent 
 June 23, 2014 

Greater Duckweed (Spirodela polyrhiza) — one of the smallest and simplest freshwater plants known — generally gets a bad rap. That’s because the millimeter-sized floating plant thrives on the worst sort of livestock and human wastewater, basically garden-variety sewage. In fact, in the South Pacific, New Zealand and Australia, it’s frequently used to clean such wastewater.

For years, researchers have been trying to commercialize duckweed as a viable source of bioenergy for the production of ethanol, biodiesel, natural gas and steam-generated electricity.

But even now, there’s little agreement on whether duckweed is best suited as a natural option for turning so-called municipal graywater into something clean enough to drink from the tap, or as a renewable biomass.  In pelletized form, it can also be used to feed tilapia, shrimp or poultry, and is even co-fired with coal.

Duckweed to bioenergy conversion may ultimately work best when done in tandem with some sort of ongoing wastewater cleanup.

The plant itself is composed of only a single kidney-shaped leaf, connected to the water on, which it floats by only a few thin underwater roots.  However, duckweed advocates point to the fact that, in warm climates, it can basically grow anywhere and at all altitudes.

A shallow big pond full of effluent from secondary treatment is just like liquid duckweed fertilizer, says Anne Marie Stomp, a retired North Carolina State University plant molecular biologist.

“You dump duckweed on top and every three days you take half of it away and the rest keeps growing,” says Stomp.

Multi-use Resource (https://renewablerevolution.createaforum.com/proxy.php?request=http%3A%2F%2Fwww.pic4ever.com%2Fimages%2F19.gif&hash=3f9f2fc2285bc756137e21463bc2a4c420b15ac3)

Duckweed also has an advantage over algae biomass;/ it is large enough that it can be easily separated from water, it is very easy to air dry and, like hay, is also easy to store. (https://renewablerevolution.createaforum.com/proxy.php?request=http%3A%2F%2Felqahera-trading.com%2Fhome%2Fwp-content%2Fuploads%2F2012%2F04%2Fdollar-sign-thumbnail1.jpg&hash=e1962ecaa694d312d50a9984ee058a45aed1e860)  (https://renewablerevolution.createaforum.com/proxy.php?request=http%3A%2F%2Fwww.clker.com%2Fcliparts%2Fc%2F8%2Ff%2F8%2F11949865511933397169thumbs_up_nathan_eady_01.svg.hi.png&hash=599691109af22b33f1d59dd61eb97448a9427020)

It may soon become more prevalent in the U.S. if the Environmental Protection Agency (EPA) places more stringent requirements on wastewater discharge permits, and small towns could be forced to comply with tertiary wastewater treatment options.

“Small towns could be forced to put in $100 million chemical tertiary treatment plants which they can’t afford,” said Stomp.  “However, duckweed is fantastically good at tertiary wastewater treatment.”

Duckweed bio-engineering could also make it even more attractive as a bioenenergy feedstock.


A paper published earlier this year in the journal Nature Communications provides new and comprehensive details of the duckweed’s genome.

“If used for ethanol or electricity, any improvement in its BTU [output] would require that you improve the carbon allocation of the organism,” said Joachim Messing, Director of the Waksman Institute of Microbiology at Rutgers University in New Jersey.

Messing, the paper’s senior author, says that, it requires knowing the duckweed’s gene content. 

“We can bio-engineer the organism so that it has a better carbon output — in some form of carbon, either sugar, protein or oil — to potentially make kerosene, gasoline or diesel,” said Messing.

Commercial Applications (https://renewablerevolution.createaforum.com/proxy.php?request=http%3A%2F%2Felqahera-trading.com%2Fhome%2Fwp-content%2Fuploads%2F2012%2F04%2Fdollar-sign-thumbnail1.jpg&hash=e1962ecaa694d312d50a9984ee058a45aed1e860)

Duckweed, however, is already capable of doubling its population in as little as 48 hours, a fact that hasn’t eluded police officer Sam Licciardello, CEO of Biomass Alternative Power in Mantua Township, New Jersey. He  is heading up a group that is investing $40 to $60 million to use duckweed to generate both electricity and natural gas by late 2015

“I will be growing duckweed in a 15-acre, gutter-connected greenhouse site,” said Licciardello.  “It will accumulate steam from the gasifiers that will run two turbines which will create electricity and supply the grid with 12 MW.  While making steam, it will also create natural gas from the duckweed which will be stored, then tested processed and released in a metered [grid] system.”

But Stomp remains skeptical.

“No one wants to fund research to figure out a high-value product from duckweed because there is no mass source or cropping system for the plant,” said Stomp.  “So, nothing but futile attempts at commercialization get started, usually by people who are passionate but have limited business sense.”

Yet Licciardello couldn’t disagree more.  ;D

Biogas Potential


For his own operation, Licciardello explains that the duckweed will be automatically harvested from six separate greenhouse sections before being screened and dried in a process that removes 75 percent of its water.  From there, it will move into a patented convection system that will use a furnace-like closed loop process to heat and burn the duckweed to create both natural gas and steam.

Duckweed is dried down to 25 percent moisture before being put into three rows of 11 gasifiers that are fired up to 1,600 degrees Fahrenheit.  The gasifiers will be automatically fed with duckweed.  The steam created from the process will travel back to the turbines.

Licciardello says a component inside the gasifiers actually separates the natural gas from the steam.  The natural gas component is then pumped into a holding tank before being fed into the natural gas grid.

Steam from the process will be fed into one of the two Siemens-built turbines at 12 MW of capacity.  Biomass Alternative Power plans on selling its electricity to Florida’s NextEra Energy.  The New Jersey start-up’s natural gas is to be purchased by British Petroleum (BP) for possible transport to California via cross-country pipeline.

When up and running, Licciardello says Biomass Alternative Power will become the only commercial duckweed-to-bioenergy conversion operator in North America.

“The production of ethanol and biogas from duckweed still cannot compete against petroleum products (gasoline and natural gas) economically,” said Jay Cheng, an agricultural and biological engineer at North Carolina State University.

It’s a view again not shared by Licciardello, however, who claims that his own start-up’s natural gas production from duckweed can already easily compete with natural gas garnered via fracking.

Once up to speed, Biomass Alternative Power will process about a million sq. ft. of duckweed per day says Licciardello.  But he remains undecided about whether his greenhouse lagoons will be filled with wastewater or whether the company will fertilize their ponds with phosphorous, nitrogen and potash.

However, revenue streams from processing wastewater treatment for counties and municipalities could arguably aid fledgling duckweed bioenergy start-ups’ bottom lines.

Duckweed in Argentina

There may even be room for more socially-conscious entities, such as Argentina’s Mamagrande, a Buenos Aires-based biotech concern that has a stated goal of “regenerating ecosystems” by using duckweed to cleanup wastewater.  It may also eventually ferment the duckweed’s starch into lactic acid to manufacture biodegradable plastic and/or bioethanol.

Funded with only several hundred thousand dollars, Mamagrande currently is working with a 4 hectare (9.88 acre) pilot plant in the small Argentinean town of Totoras.

Eduardo Mercovich, one of Mamagrande’s co-founders, says the initial cost of the duckweed needed to get such projects going is almost negligible.  That’s in part because, as he notes, usually within a month’s time, the plant can grow to cover a hectare (2.47 acres) of a lagoon’s surface area.

“In our pilot plant,” said Mercovich, “we should have ten fresh wet tons of duckweed per day; or about a quarter ton of starch per day; half of which would produce 100 liters of ethanol daily.”

Mercovich says that once Mamagrande’s duckweed process is proven in Argentina, its technology will be made publicly available.  He notes that in both Brazil and Argentina, ethanol is currently made from either corn or sugar cane.  But unlike cane or corn, as Mercovich points out, duckweed needs less energy to process.

Bioengineering Starch for Ethanol

If future duckweed bioenergy entrepreneurs can find some sort of revenue-generating synchronicity with global municipalities interested in cleaning up wastewater — either to be reused as graywater for agricultural irrigation or for drinking water — then duckweed may find a viable bioenergy conversion niche.  And as Stomp points out, it also compares favorably with corn, as it is likely easier to isolate starch from duckweed. 

After over 15 years of duckweed research in the laboratory, Stomp explains that she and Cheng proved that once loaded into a fermentation vessel, more than 95 percent of its starch could be converted into ethanol.

“By growing duckweed on wastewater from hog production,” said Stomp, “we harvested duckweed biomass at the rate of 20 grams of dry weight per sq. meter a day, which is equivalent to 54,000 kg of dry weight on 2.5 acres a year.”

Stomp notes that if this 54,000 kg of dry weight duckweed were only 50 percent starch then it would yield something like 27,000 kg of starch for every 2.5 acres, or roughly four times the starch that could be expected from 2.5 acres of corn.

Stomp, however, says that by using enzymatic degradation of corn stover, the traditionally unused portion of a corn plant for ethanol conversion itself, then that “drastically” increases dry weight biomass that can harvested from an acre of corn.

But with bioengineering, duckweed would likely still have an edge on corn.

“You could probably trick this plant into accumulating starch to as much as 75 percent; [roughly] the same starch percentage as corn,” said Stomp. *

 http://www.renewableenergyworld.com/rea/news/article/2014/06/the-ugly-duckling-can-duckweed-find-its-way-to-bioenergy-commercialization

* Agelbert NOTE: Not mentioned is the fact that it takes MUCH longer to get that "high percentage of starch" in corn than the 40% or so in Duckweed. Also, ALL of the duckweed has that starch content whereas corn only has it in the seed with LOTS of wasted energy (from a starch production standpoint) used to make the rest of the plant with a huge stalk and root system. Duckweed is ALL usable product. Duckweed has much less lignin content that corn. Lignin is the THE biggest chemical bugaboo obstacle because it is expensive to rid the feed stock of it in preparation for making biofuel. So yeah, duckweed beats the living daylights out of corn and even switchgrass, never mind that corn and switchgrass have short growing seasons and Duckweed can be grown ALL YEAR.   (https://renewablerevolution.createaforum.com/proxy.php?request=http%3A%2F%2Fwww.createaforum.com%2Fgallery%2Frenewablerevolution%2F3-141113185047.png&hash=384024358ff8d5e7133d19b6e6638da4584a8154)

Great Article! I just want to add the tiniest flowering plant known to science (Lemna minor - Duckweed), also has great promise as a source of nutrition and bioremediation of the environment at the same time.

This wonder plant grows almost everywhere on earth, can be fertilized with pig feces, thereby avoiding chemical fertilizers and nitrogen waste farm runoff, grows in shallow ponds with no need of continual water resupply once the initial pond is set up, does not replace crop land because ponds can be placed over non arable land all over the world to help sequester carbon, can be used as feed for animal and nutrient supplements for humans to prevent malnutrition, have even been used as environmental markers to detect heavy metal pollutants in water and, last but not least, is a known natural water purifier (lower the fecal coliform count to acceptable levels).

The Chinese have actually proposed Duckweed refineries because, as long as crude oil costs more that $80 a barrel, biofuel hydrocarbons form the Duckweed carbohydrates are profitable. Duckweed, unlike many cellulose biofuel plant sources is extremely low in lignin . This makes the extraction process far simpler, cheaper and more environmentally friendly that making biofuel out corn (a horrible choice only a fossil fuel lover could like) or even sugar can, which is eight times more efficient as a biofuel source than corn. Even switchgrass varieties have more lignin than Duckweed.

I am firmly convinced this humble plant is part of a human future in a viable biosphere. I have video and research data as well as links below.

Agelbert NOTE: Although the following post is about duckweed as a bio-fuel source, it is just as important, if not more so, to understand that duckweed is the ONLY plant out there that could actually lower the amount of CO2 in our atmosphere. This, of course, would be contingent on the banning of the burning of fossil fuels. We know the corrupted powers that be don't want to do that.  >:( But even if they don't, they will soon be FORCED to seek out the plant that is most likely to "sequester Carbon" (what a ridiculous bit of jargon for absorption of CO2!) at a rate that could start us on the way back to 280PPM of CO2 (Pre-industrial levels).

The geo-engineering techno-fix fossil fuel industry SCAM simply will not work. But the fossil fuel industry corrupted governments all over the world will probably try it, which will certainly make some people rich while it makes things worse for the biosphere. (https://renewablerevolution.createaforum.com/proxy.php?request=http%3A%2F%2Fwww.createaforum.com%2Fgallery%2Frenewablerevolution%2F3-200714183337.bmp&hash=fd5a6df63c32bd65dda7b6d93e788647ca3829df)

A massive Duckweed production campaign all over presently non-arable land areas would work IF if  banned the burning fossil fuels completely.

That would be the intelligent and prudent thing to do.

So, we can count on our fossil fuel industry corrupted governments to NOT do it.  (https://renewablerevolution.createaforum.com/proxy.php?request=http%3A%2F%2Fwww.createaforum.com%2Fgallery%2Frenewablerevolution%2F3-200714183337.bmp&hash=fd5a6df63c32bd65dda7b6d93e788647ca3829df)

Pond-dwelling powerhouse’s genome points to its biofuel potential


Duckweed is a tiny floating plant that’s been known to drive people daffy. It’s one of the smallest and fastest-growing flowering plants   ;D that often becomes a hard-to-control weed in ponds and small lakes. But it’s also been exploited to clean contaminated water and as a source to produce pharmaceuticals. Now, the genome of Greater Duckweed (Spirodela polyrhiza) has given this miniscule plant’s potential as a biofuel source a big boost. In a paper published February 19, 2014 in the journal Nature Communications, researchers from Rutgers University, the Department of Energy Joint Genome Institute and several other facilities detailed the complete genome of S. polyrhiza and analyzed it in comparison to several other plants, including rice and tomatoes.

Duckweed, a small, common plant that grows in ponds and stagnant waters, is an ideal candidate as a biofuel raw material.  (https://renewablerevolution.createaforum.com/proxy.php?request=http%3A%2F%2Fwww.pic4ever.com%2Fimages%2F128fs318181.gif&hash=eff6d5f3831782966c2ff2081f07bf7fc5b22a6b) ;D Photo (at link) by Texx Smith, via flickr
 
Simple and primitive, a duckweed plant consists of a single small kidney-shaped leaf about the size of a pencil-top eraser that floats on the surface of the water with a few thin roots underwater. It grows in almost all geographic areas, at nearly any altitude. Although it’s a flowering plant, it only rarely forms small indistinct flowers on the underside of its floating leaves. Most of the time, it reproduces by budding off small leaves that are clones of the parent leaf. It often forms thick mats on the edges of ponds, quiet inlets of lakes and in marshes. It’s among the fastest growing plants, able to double its population in a couple of days under ideal conditions.

These and other properties make it an ideal candidate as a biofuel feedstock – a raw source for biofuel production. For example, unlike plants on land, duckweeds don’t need to hold themselves upright or transport water from distant roots to their leaves, so they’re a relatively soft and pliable plant, containing tiny amounts of woody material such as lignin and cellulose. Removing these woody materials from feedstock has been a major challenge in biofuel production. Also, although they are small enough to grow in many environments, unlike biofuel-producing microbes, duckweed plants are large enough to harvest easily. ;D

S. polyrhiza turns out to have one of the smallest known plant genomes, at about 158 million base pairs and fewer than 20,000 protein-encoding genes. That’s 27 percent fewer than Arabidopsis thaliana – which, until recently, was believed to be the smallest plant genome – and nearly half as many as rice plants.

Spirodela is one of the smallest plants in the world. Here (at the link)it is displayed with other comparable plants.

 
“The most surprising find was insight into the molecular basis for genes involved in maturation – a forever-young lifestyle,” said senior author Joachim Messing, director of the Waksman Institute of Microbiology at Rutgers University.

S. polyrhiza leaves resemble cotyledons, embryonic leaves inside plant seeds that become the first leaves after germination. But where other plants develop other kinds of leaves as they mature, S. polyrhiza’s never progresses and continuously produces cotyledon leaves. This prolonging of juvenile traits is called “neoteny.” S. polyrhiza had fewer genes to promote and more genes to repress the switch from juvenile to mature growth.

“Because of the reduction in neoteny, there is an arrest in development and differentiation of organs. So this arrest allowed us to uncover regulatory networks that are required for differentiation and development,” Messing said.

Also intriguing to the research team were which genes were preserved over time and which were not. Many of the genes responsible for cellulose and lignin production in land dwelling plants were missing, (https://renewablerevolution.createaforum.com/proxy.php?request=http%3A%2F%2Fwww.clker.com%2Fcliparts%2Fc%2F8%2Ff%2F8%2F11949865511933397169thumbs_up_nathan_eady_01.svg.hi.png&hash=599691109af22b33f1d59dd61eb97448a9427020)  and there were fewer copies of those that were present. Genes for another compound related to cell walls called “expansins” which are involved with cell wall and root growth were also reduced.

Genes for starch production, on the other hand, were retained and are probably used for creating starch-filled turions, specialized buds produced by aquatic plants for overwintering, enabling them sink to the bottom of ponds and revive in warmer weather. Moreover, despite the reduced number of total genes, S. polyrhiza has more copies of genes for enzymes involved in nitrogen absorption and metabolism than in other plants. This is probably linked to the plant’s ability to utilize excess nitrogen in contaminated waters.

A thorough understanding of the genome and cellular mechanisms of S. polyrhiza could greatly enhance current efforts to recruit duckweed as a biofuel source.Messing estimates that duckweed will be a viable biofuel source within the next five years and points to Ceres Energy Group in New Jersey, which is already producing electricity from duckweed. (https://renewablerevolution.createaforum.com/proxy.php?request=http%3A%2F%2Fwww.pic4ever.com%2Fimages%2F19.gif&hash=3f9f2fc2285bc756137e21463bc2a4c420b15ac3) Understanding which genes produce which traits will allow researchers to create new varieties of duckweed with enhanced biofuel traits, such as increased reduction of cellulose or increased starch or even higher lipid production. Starch can be directly used as a biofuel source and it can be converted to ethanol, the way corn is currently converted to ethanol fuel, but oils would have greater energy than ethanol.

“Classical breeding or genetics does not apply here because of its clonal propagation and rare flowering, but these organisms can be transformed with DNA,” Messing said. “Therefore, new variants can be created with modified pathways for industrial applications. These variants would be an enhancement over what can be done now.”

This genome was sequenced as part of a DOE Office of Science JGI Community Science Program (CSP) project (formerly the Community Sequencing Program). It exemplifies the collaborative approach and innovative projects that the CSP enables among researchers. Messing pointed to the study’s advances over previous research.

“The sequencing of this genome opens new frontiers in the molecular biology of aquatic plants,” said Messing. “This publication represents the single largest advance in this field and a new milestone in plant molecular biology and evolution, as previous studies were either classical botany or biochemistry of photosynthesis. The placement of the Spirodela genome as a basal monocot species will serve as a new reference for all flowering plants.”

And, of course, UNLIKE steel, which requires polluting mining, heating, beating and treating, we can grow as much as we need (it grows quite well in MANY areas, including Puerto Rico, all over the world) sustainably.

Maersk Signs Up H&M for Carbon-Neutral Biofuel Trial

June 20, 2019 by Mike Schuler

Danish shipping giant Maersk says fashion group H&M has become the first company to sign up to trial a new carbon-neutral offering that utilizes the use biofuel to eliminate carbon emissions from shipping.

Maersk says the biofuel in the pilot project is the same blend of used cooking oil and heavy which has been tested and successfully validated in a trial driven in collaboration with the Dutch Sustainability Growth Coalition (DSGC), and Shell his year. It is also certified as a sustainable fuel by the International Sustainability & Carbon Certification (ISCC) body.

The new carbon neutral product will be made available to select Maersk customers who are looking reduce or eliminate carbon emissions from their supply chain.

Back in March, the containership Maersk Maersk set sail on a round trip from Rotterdam to Shanghai using a blend of biofuel produced from plant waste, marking the industry’s biggest tests to date of the fuel.

“The biofuel trial on board Mette Maersk has proven that decarbonized solutions for shipping can already be utilized today, both technically and operationally. While it is not yet an absolutely final solution it is certainly part of the solution and it can serve as a transition solution to reduce CO2 emissions today. With the launch of this product, Maersk seeks to help our customers with their goal of moving to sustainable supply chains,” said Søren Toft, Maersk COO.

Maersk says the goal of the pilot is to ultimately unlock the potential of sustainable fuels to the point where they are commercially available. Maersk itself has actually set a target of becoming carbon-neutral by 2050.

For H&M, the project offers the opportunity to reduce carbon emissions from ocean transport.

“Our high ambition to become climate positive by 2040 requires cooperation and engagement from all parties in the supply chain. We want to use our size to be a force for good and enable scaling innovative solutions, such as the carbon neutral ocean product, for a greener commercial transport,” says Helena Helmersson, COO H&M Group.
