Why is incinerator energy not renewable?
The energy-producing capabilities are often thought to mitigate the effects of this pollution, but the energy created by incinerators is not the kind of energy that needs to be produced because is not renewable. It is derived from the waste of products that are created from finite resources. This creates a demand for more waste that then discourages recycling, which is so necessary to conserving our invaluable natural resources.
What are the pollutants that are captured by filters?
The pollutants that are captured by filters still pose an environmental problem since they have to be disposed of in landfills. This ash from incinerators often contains dangerous heavy metals, which, when placed in landfills, then end up polluting our air, soil, and water.

Why is incinerator energy used?
In most incinerators and all newly constructed ones, the heat released from burning waste is used to produce electricity. This electricity can help to offset the cost of building and maintaining the facility (which is usually significantly more expensive than landfilling). On the EPA’s waste management hierarchy, energy recovery is less efficient than recycling and ranks above disposal. Recycling, of plastic at least, saves more energy than combustion generates. But recycling plastic has become its own challenge, and many communities have been forced to treat plastic as nonrecyclable.
How is waste incinerated?
The Waste Incineration Process 1 Waste preparation: Oversized items are removed and certain recyclables like metals are recovered. The remaining waste is often shredded before it enters the incinerator. 2 Combustion: Waste is burned in an oxygenated single combustion chamber. Materials are burned at extremely high temperatures of 1,800-2,200 degrees Fahrenheit. At those temperatures, waste should be completely combusted, leaving nothing but gases and ash. 3 Energy recovery: The gases released during combustion are cooled with water, generating steam through heat recovery. The steam is used to power electrical generators. 4 Environmental control: The cooled gas is treated by scrubbers, precipitators, and filters to remove pollutants. The solids that form during treatment, called residuals, are disposed of in a landfill. 5 Environmental release: The treated gas is released to the atmosphere. There should be no visible smoke from the smokestack because the remaining gases should be free from particulates.
What percentage of MSW goes to landfill?
But waste also remains after burning. From 15-25 percent (by weight) of the MSW burned remains as bottom ash that goes to the landfill. Many people fear that incineration conflicts with efforts to reduce waste.
Why is incineration used in landfills?
Because incineration utilizes such high temperatures, it can destroy many pathogens and some toxic materials. For this reason, incineration is the preferred method of disposal for biomedical and some other special wastes, even in communities where MSW is landfilled.
