Ethanol and the Energy Question
is an ethanol alternative that does not use food as a feedstock. It uses a
negative-cost feedstock that we have plenty of: garbage.
municipal and industrial waste generated in the United States could provide up to
50 billion gallons per year of clean transportation fuels through the use of
plasma gasification. It could also provide a substantial reduction in
greenhouse gas emissions by eliminating methane gas from landfills.
on progress over the last two decades, waste conversion using plasma
gasification has become a commercial reality as an environmentally friendly and
economical way to transform waste material into clean energy.
