What do we mean by waste-to-energy? This term describes the process of creating energy such as heat or electricity from the burning of waste. Waste-to-energy is a form of energy recovery, and it is another way to utilize our garbage instead of placing it in a landfill. Modern facilities manage to keep pollution low while generating light for nearby cities, for example.
Some landfills also collect and process gases produced on site to create electricity and fuel. Read more about these types of waste-to-energy projects here.
