With the passing of Halloween, millions of pounds of pumpkins have turned from seasonal decorations to trash destined for landfills, adding to more than 254 million tons of municipal solid waste (MSW) produced in the United States every year. This Halloween, think of turning this seasonal waste into energy as a very important “trick” that can have a positive environmental and energy impact. At landfills, MSW decomposes and eventually turns into methane—a harmful greenhouse gas that plays a part in climate change, with more than 20 times the warming effect of carbon dioxide (CO2). However, when MSW is used to harness bioenergy—rather than simply being thrown away—the end result benefits the environment and helps our nation become less dependent on carbon-based fuel. Harnessing the potential of bioenergy allows the United States to generate its own supply of clean energy that reduces greenhouse gas emissions. It also limits stress on landfills by reducing waste and could ultimately create jobs for manufacturing, installing, and maintaining energy systems. The Energy Department’s Bioenergy Technologies Office is working together with industry to develop and test integrated biorefineries—facilities capable of efficiently converting plant and waste material into affordable biofuels, biopower and other products. These projects are located around the country and use a variety of materials as feedstocks….
