how can we get energy from wastes.
Answers
One way to generate electricity is to burn solid waste, like the material found in landfills. Instead of a traditional landfill, a community might have a waste-to-energy facility that incinerates garbage, transforming chemical energy to thermal energy.
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.S. 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.
