Israel makes Biofuel from "Seaweed". I have considered previously the possibilities of making biodiesel from algae, which can in principle be achieved on an amount per hectare some 100 or more times that derived from common "bio-crops". Against the backdrop of conventional oil supplies running short within a decade and the serious compromise th

According to an article [*.pdf] in the August issue of Microbiology Today , this technology has an added bonus: leftover enzymes can be used to scavenge precious metals from spent automotive catalysts to help make fuel cells that convert hydrogen into energy. Hydrogen has three times more potential energy by weight than petrol, making it the highest energy-content fuel available. Research into using bacteria to produce hydrogen from waste biomass has been revived thanks to the rising profile of energy issues. According to the researchers, the UK throws away a third of its food, wasting 7 million tonnes a year. The majority of this is currently sent to landfill where it produces gases like methane, which is a greenhouse gas 25 times more potent than carbon dioxide. Following some major advances in the technology used to make biohydrogen, this waste can now be turned into valuable energy. Two-stage process There are special and yet prevalent circumstances under which micro-organisms have no better way of gaining energy than to release hydrogen into their environment. Microbes such as heterotrophs, cyanobacteria, microalgae and purple bacteria all produce biohydrogen in different ways, says Dr Mark Redwood from the University of Birmingham. When there is no oxygen, fermentative bacteria use carbohydrates like sugar to produce hydrogen and

"he Digest investigates.   In science, there exists the difficulty in developing a new energy crop -  improving yields and stress tolerance, identifying the right geographies for deployment, developing and sharing the agricultural practices and training, and so on.  A number of new energy crops and residues have been brought along by companies such as Agrisoma, SGB, Yulex, Ceres, Chromatin, NexSteppe and more, despite the odds. But there also has been the difficulty in developing an economic model for deployment, that proves more attractive and safe than the "here's your seed, get going" approach that has proven uninspiring to local growers. So, along comes Bosques Energeticos.  In fact, that's what the Bosques multi-year, multi-crop strategy is all about. In their model, growers plant castor as a lower-value, but relatively instantaneous oilseed cash crop - at the same time as jatropha is planted for the mid-term, and pongamia is planted for the long-term. In today's Digest we look at: What's different about Bosques - Legendary's interest - Pon-What? - Following the agronomy - improving yields and speed, margins and yields - the models, the next steps and The Bottom Line - at biofuelsdigest.com.      REG- Developing next-generation biofuels - investing in technology VecoPlan - shredding, conveying, screening, separating, storing The Latest in Brief   Turkey blocks US DDGS due to GMOs In Turkey, the country is effectively no longer accepting imports of U.S. corn coproducts following the stepped-up enforcement of existing biosafety laws that restrict which genetically modified (GM) corn varieties may enter the country's grain supply. As of Dec. 8, three shipments of U.S. distillers dried grains with solubles (DDGS) have been rejected following the detection of unapproved GM events, and for the same reason at least one other vessel of U.S. DDGS has been diverted from Turkey to another buyer while on the water.   Maine towns take first step in developi

Biohydrogen (gasification) Besides production of biohydrogen from biogas, it can also be produced through gasification of biomass, similar to the production of bio-SNG, which was discussed above. A gasification method has to be used that produces a gas w

About 100 million pigs, 35 million cattle, 1.6 billion turkeys and 8 billion chickens are slaughtered and processed each year in the United States. The USDA requires facilities that process these meats to use large volumes of clean water to continuously rinse the meats as they are cut and packaged. These large volumes of water contain extremely high levels of protein and fat that are later removed by using conventional but highly efficient wastewater processing methods. The result of these processes is a cleansed wastewater and a co
