Waste-to-Energy (WTE) facilities combust municipal solid waste (MSW) to produce electrical energy. Florida has grown from having one small WTE plant in 1982 to 11 operating WTE facilities as of 2011. Florida has established the largest capacity to burn MSW of any state in the country. Standards for the handling, processing, disposal, and recycling of MSW combustor ash are contained in Chapter 62-702, Florida Administrative Code. Ash is required to be disposed in a lined MSW landfill or a lined ash monofill, since an Environmental Protection Agency study showed that ash from WTE facilities should not be classified as hazardous waste.
