This article explores various combustion technologies for municipal solid waste (MSW), including mass burn, gasification, pyrolysis, and anaerobic digestion. It provides insights into combustion residues like flue and bottom ash, the processes that convert waste into energy, and how these technologies handle MSW. Additionally, it discusses the production of syngas, recyclable materials, and marketable products like compost, showcasing their relevance in waste management and energy production in facilities across the United States.

Existing MSW combustion technologies generate residue called “flue” and “bottom” of this material.
This is the most common type of combustion facility for MSW operating in the US.
This technology can be found at the front end of a gasification, pyrolysis, or anaerobic digestion facility in addition to operating as a stand-alone technology to extract recyclable materials from MSW.
The number of MSW waste-to-energy facilities operating in Texas.
The gas produced by gasification, primarily comprised of hydrogen, carbon monoxide, and methane, is referred to as this.
Less of this is injected into the gasification combustion chamber than in more proven combustion technologies resulting in less residue.
MSW entering a gasification chamber typically needs to be reduced in size to between 2 and 12 of these.
The number of commercialized gasification facilities operating at full scale in the United States processing MSW.
Plasma arc technology “vitrifies” the residue into a solid with similar properties to this recyclable material.
Used in plasma arc technology to create an electric field that converts gas into heated and ionized plasma …. And at the Olympics.
This Canadian capital city in Ontario has one of the few plasma arc facilities in North America operating full-scale processing MSW.
The number of commercialized plasma arc gasification facilities operating at full scale in the United States processing MSW.
The material most commonly used as feedstock for this technology.
In addition to gas that can be used for energy, this liquid product may be produced by pyrolysis.
The number of commercialized pyrolysis facilities operating at full scale in the United States processing MSW.
The type of MSW that is commonly used as feedstock for this technology.
A marketable product made from the digestate from anaerobic digestion.
What aerobic digestion adds to the process that anaerobic digestion does not.
