✦ Synopsis
be placed in jeopardy if there is truth in the claims by Coskata that it has discovered a process for the cheap and environmentally friendly production of biofuels which does not require enzymes, chemicals, or the pre-treatment of biomass. The two Danish firms have invested heavily in the production of enzymes for biofuel manufacture. The process involves microorganisms consuming syngas and can apparently be carried out at low temperatures and pressures. Coskata has developed a method which delivers 7.7 times more energy than it consumes and produces 378 litres ethanol per tonne biomass. Carbon dioxide production is 84% less than that of conventional petrol production. Coskata says the process could revolutionize the ethanol industry with backing from General Motors and its partners. It can be used with nearly all crops and agricultural waste throughout the world.
