And while we’re at it let’s get goats into the act.
But first, UCLA researchers are studying the use of the human feces as biofuels to power cars. David Wernick, graduate student of UCLA, notes that poop is an untapped resource that only gets flushed in toilets.
In the US, just counting animal manure, more than 1 billion tons of poop are produced yearly. But Wernick and his colleagues are also trying other materials to produce new kinds of biofuels such as sewage waste, plant matter, cellulosic matter and carbon dioxide from the atmosphere, Gizmodo reported
The UCLA team plans to engineer the bacteria in human waste by breaking down the proteins in excrement and other waste rich in protein such as wastewater algae and byproducts from the fermentation of beer, ethanol and wine. Wernick believes that the re-engineered bacteria, when it uses the protein to produce poo-based biofuels, would result is the vehicle running without a need to adjust its automotive parts.
BBC recently reported that fungi found in goat and sheep stomachs can break down vegetation in a way that may be useful for biofuel production. Most biofuel in the United States comes from crops such as corn, but growing corn takes a lot of land, and using it for biofuels may drive up food prices. So the industry is increasingly looking toward nonfood sources of biomass like grass and wood. In a study published in Science, researchers show that fungi isolated from the feces of goats and sheep can break down wood better than the standard processes in place. Plus, these fungi can change which digestive enzymes they produce in response to what they are eating, making them more flexible than traditional methods.
Renewable energy is all about looking at everything in new ways, including our own poop…oh, and goats.
Update on lithium ion batteries:
Starting on April 1, the International Civil Aviation Organization (ICAO) will ban shipments of lithium-ion batteries as cargo on passenger aircraft due safety concerns. According to Lloyd’s Loading List.com, the decision is “binding on all (191) ICAO Member States and therefore the airlines which operate in those States.”
This is the latest in a national and international efforts to restrict shipments of lithium-ion batteries as cargo. Last month I posted that the Federal Aviation Administration issued a “safety alert” urging U.S. and foreign commercial passenger and cargo airlines to conduct “a safety risk assessment to manage the risks associated with transporting lithium batteries as cargo.” The FAA also issued a guidance to its own inspectors to help them determine whether airlines have adequately assessed the risk of handling and carrying lithium batteries as cargo.
Genera recently published an infographic overview of different biomass feedstocks and guidelines for choosing the best solution for every biomass project. The infographic highlights key supply chain elements and explores which biomass crops are best suited for an application.
While not comprehensive to all feedstocks, the document gives customers, stakeholders, and policy makers a better understanding of the unique dynamics associated with biomass feedstocks.
Genera says choosing the right feedstock or feedstock portfolio is critical to the success of any project. “In many cases, raw feedstock is 50 percent or more of the total cost of producing renewable biofuels and biochemical. Optimizing a project’s feedstock portfolio has a significant impact on profitability.”
Pacific Northwest aviation and renewable energy interests say there are encouraging signs of an emerging market for sustainable aviation fuels. And those same interests want to make it real.
The Sustainable Aviation Fuels Northwest consortium, in a report this month, concludes that no single feedstock or technology pathway is likely to provide sustainable aviation fuel at the scale or speed needed to produce and maintain jet fuel supply.
Therefore, the 132-page report, “Powering the Next Generation of Flight,” focuses on a portfolio of options, including different conversion technologies and sources of potentially sustainable biomass, including oilseeds, forest residues, solid waste, and algae.
Instead of trying to single out the best source of aviation fuels, SAFN emphasizes the need to create “complete supply chains that can draw upon diverse feedstocks.” Read the rest of this entry »
This is really neat but will using solar power to create fuel have long-term legs? We’ll see – at some point alternative, renewal fuel ideas will have to catch on, won’t they?
Anyway this one is called solar biomass gasification, a concept and process that’s been around for some time, mostly in university scientific research circles. A relatively new company that has emerged from that university research environment, Sundrop Fuels Inc., might have the drop on making a commercial go of it.
CEO Wayne Simmons puts it quite succinctly: “We’re going to convert the sun’s energy into liquid fuel using concentrated solar power to gasify biomass, then convert the resulting syngas into green gasoline or diesel.”
The Washington State Algae Alliance, which includes two bioscience firms and the Washington State University, is set to receive $2 million from funding provisions in the 2010 Senate Energy and Water Development appropriations bill.
Sen. Patty Murray (D-WA) was instrumental in securing the funding for the Alliance, which will jointly develop a new algae-based system for the production of sustainable and renewable fuels, chemicals, and chemical intermediates.

The rankings were based 50 percent on votes from a 75-member panel of international selectors, and 50 percent on votes from subscribers of Biofuels Digest.
It feels like a natural for the Scots to come up with a way to get energy out of whiskey.
If you like your whiskey neat or on the rocks or even if you don’t drink this is pretty neat: Helius Energy Plc and the Combination of Rothes Distillers (CoRD) formed a joint venture known as Helius CoRDe, that will build and operate a biomass energy plant using whiskey distillery by-products.
The proposed £50 million ($82.7 million) project would reduce the carbon footprint of the whiskey industry on the Scottish island of Speyside.
The plant will use whiskey distillery byproducts to fuel a 7.2-megawatt GreenSwitch biomass combined heat and power plant and a GreenFields plant that will turn the liquid co-product of whisky production, known as Pot Ale, into a concentrated organic fertilizer and an animal feed for use by local farmers.
Helius CoRDe will be responsible for the financing, construction and operation of the new plant. The project could save more than 20,000 tons of carbon dioxide each year when compared to CoRD’s current energy use, the distillers say.
“This agreement formalizes the work we have undertaken so far and sets out the structure for us to take this project forward to completion,” says Frank Burns, CoRD general manager. “ The ability to generate renewable heat and power and secure additional markets for our distillery co-products is a very exciting development for the malt whisky industry on Speyside.”
Officials said they anticipate that engineering procurement and construction contract awards likely will come soon, allowing plant construction to begin in early 2010. It will take about two years to complete project construction.
And there’s more recent action on the Scottish biomass front with word late last month that Forth Energy, a joint venture created last year between Forth Ports Plc and Scottish and Southern Energy is preparing to go ahead with the development of four dedicated biomass power stations at Forth Ports’ site in Scotland.
Plants are proposed for Dundee, Leith, Rosyth and Grangemouth. Installed capacity would total around 400 megawatts. Softwood sourced from forests in the UK and overseas would provide the main source of fuel.
Pot Ale is a high-protein co-product removed prior to final distillation of the spirit. The solid grain product removed from the mash tun, prior to fermentation of the liquor, is known as draff.
The GreenFields process takes the co-products from distillery operations (including process water, pot ale and draff) and turns them into “value inputs” such as biomass fuel, soil conditioner, animal feed and water for cooling and cleaning purposes.
The combined heat and power unit will use a combination of distillery co-products and wood chips from sustainable sources to generate the 7.2 megawatts of electricity, enough for 9,000 homes, which can be used onsite or exported to the National Grid.
CoRD was founded in 1904 to process the Pot Ale produced by the whisky distilleries in the Rothes area. It is owned by a combination of distilling companies – comprising The Edrington Group, Chivas Brothers, Glen Grant Distillery Ltd, Inver House Distillers, Diageo and Benriach Distillery Co.
“Biomass will play a major role in meeting the UK’s targets for emissions reductions, and [the Helius CoRde venture] is a model that has the potential to be rolled-out elsewhere. Drinking green whisky may give you a warm glow but it’ll also help to avoid warming the planet,” says John Seed, managing director of Helius Energy.
So drink responsibly and don’t drive but if you do overdo it on occasion the morning-after guilt might not be so bad, if you can remember the biomass angle. Or not.
