Regardless of what is being burned (mixed municipal solid waste, plastic, outputs from “chemical recycling”), waste incineration creates and/or releases harmful chemicals and pollutants, including: Air pollutants such as particulate matter, which cause lung and heart diseases.

For every 100 tons of trash burned, 30 tons become toxic ash that goes to landfills. The other 70 tons don't turn into energy, but become air pollution. In terms of air pollution, and groundwater impacts, burning waste then burying ash is far worse than direct landfilling, and both are worse than a Zero Waste approach.

Why Use Incineration? Incineration can destroy a wide range of highly contaminated wastes and greatly reduce the amount of material that must be disposed of in a landfill. For small contaminated areas, excavation and transport to an offsite incinerator can be a quick cleanup approach.

Pros of Incineration: Waste Reduction: Incineration can reduce the volume of waste by up to 90%. This means that less waste ends up in landfills, reducing the need for more landfills. Energy Generation: Incineration can also generate electricity, which can be used to power homes and businesses.
