Fuels gold

The increased interest in biofuels (fuels derived from organic matter) is described. Supporters claim they will reduce emissions of greenhouse gases but scientists have begun to question the environmental and social arguments for bioethanol and biodiesel. There are claims that biofuels will reduce rainforests and water reserves and raise fuel prices. Brazil produces bioethanol from sugar cane and produces 10% of its fuel consumption from only 3% of its land. USA is working on the production of biofuels from corn. The percentage of agricultural land needed to replace 10% of transport fuel with biofuel is discussed with reference to different feedstocks (corn, wheat, vegetable oils, sugars, wastes and fibres). Research is being conducted into the production of biofuels from cellulose in different countries and non-food crops such as switchgrass. Canadian company, Iogen, has built a pilot plant that is producing cellulose ethanol using a genetically modified tropical fungus that produces enzymes that can break down cellulose. (A)
