Waste-To-Energy as an Alternative Energy Source
The Waste-to-Energy (WtE) industry, like biomass, has seen a large focus over recent years as a potential alternative energy source, the difference being that biomass is a renewable and sustainable energy that can provide carbon credits and a reduction in carbon footprint by supplementing fossil fuels. WtE attraction can also provide carbon offsets but is often cost driven, by avoidance of tipping fees, or cost of waste disposal.
WtE industries are characterized by two general types, incineration or combustible fuels. Incineration applications take a solid or liquid waste product and convert it to heat energy for use in co-generation (co-gen) or process heat applications. Some common waste products being used or evaluated include municipal solid waste (MSW), landfill waste, medical waste, urban wood waste (demolition debris), tree trimmings, etc.
