Presentation transcript:

What is incineration? A controlled process in which mixed garbage is burned at very high temperatures Reduces volume of trash by up to 90% Metals removed before burning Reduces weight of waste by up to 75%

Addressing the Problems of Incinerations Problems of Incinerators Current Technologies Ash may still contain toxic waste Bury in a hazardous waste landfill Burning may release hazardous chemicals (dioxins, heavy metals, and PCBs) into the atmosphere Scrubbers chemically treat gases by neutralizing them Burn the garbage at especially high temperatures

What is waste-to-energy? Facilities use heat produced by incineration to boil water, creating steam that drives electricity
