"What we get from that is a very pure, high-quality fuel," said Counsell, at the Advanced Biofuels Leadership Conference in National Harbor, Md., Wednesday. Turning trash into fuel yields twice the energy that incinerating the waste for electricity would provide, he added. Recent life-cycle analyses indicate that the fuel could reduce greenhouse gas emissions by up to 95 percent compared to fossil fuels, said Counsell. This doesn't include the avoided methane emissions -- a gas with 30 times the global warming potential of carbon dioxide -- that result from trash decomposing in a landfill.
