That thermal energy is transformed into electrical energy, usually by turning a turbine. Another energy resource that comes from our garbage is the methane gas that is produced as the waste decays. This gas can be used as fuel. Hundreds of waste-to-energy plants are in operation in Europe and there are around 90 in the U. Although incineration has been around for centuries, modern waste-to-energy facilities must meet strict guidelines to capture pollutants, like dioxin, that would normally be released into the air.

Energy recovery from waste is important in the development of sustainable energy policies. EPA continues to develop regulations that encourage energy recovery from hazardous materials or materials that might otherwise be disposed of as solid waste. The non-hazardous secondary material NHSM final rule under the Resource Conservation and Recovery Act RCRA identifies which non-hazardous secondary materials are, or are not, solid wastes when burned in combustion units.
This determines which Clean Air Act emission standards a combustion unit is required to meet. Gasification is a process that converts any material containing carbon—such as coal, petroleum or biomass—into synthesis gas syngas composed of hydrogen and carbon monoxide. The syngas can then be burned to produce electricity or further processed to produce vehicle fuel. This exclusion ensures that the gasification of these materials will have the same regulatory status i. Waste minimization, the term employed in the RCRA statute, is defined to include both source reduction and certain types of environmentally sound recycling.
EPA's highest priority is to achieve reductions through source reduction. However, if this is not achievable, then environmentally sound recycling is also an Agency priority. Recycling activities closely resembling conventional waste treatment activities such as burning for energy recovery do not constitute waste minimization. Also, treatment for the purposes of destruction or disposal is not part of waste minimization, but is, rather, an activity that occurs after the opportunities for waste minimization have been pursued.

Which regulations apply to energy recovery from waste? Does EPA consider burning for energy recovery to be waste minimization? Energy Recovery from Combustion Energy recovery from the combustion of municipal solid waste is a key part of the non-hazardous waste management hierarchy , which ranks various management strategies from most to least environmentally preferred.
Combustion Technologies Common technologies for the combustion of MSW include mass burn facilities, modular systems and refuse derived fuel systems. Mass Burn Facilities Mass burn facilities are the most common type of combustion facility in the United States.
We favour the integrated treatment approach. Our installations are adapted to produce compost and biomass. Therefore, Indaver always determines how to recover materials in the best and most efficient manner: as a material or as energy. Toggle Search Toggle navigation. Share this page.
