While policy momentum behind biofuels has sputtered in recent months due in part to a slumping economy, indirect land use change debates, and life cycle studies concluding that “green” fuels cause more greenhouse gas emissions than conventional fuels, using waste as a fuel feedstock represents a promising shortcut on the path to energy security.
Waste-to-fuel is nothing new, but it remains a vastly underdeveloped alternative despite being cheap, abundant, and according to the EPA, renewable. More recently, a convergence of environmental, economic, and energy factors have bolstered the development of increasingly innovative waste-to-energy solutions.
