Plasma gasification is a thermal process that converts organic matter into a syngas (synthesis gas) which is primarily made up of hydrogen and carbon monoxide. A plasma torch powered by an electric arc ionizes gas and transforms organic matter into syngas, producing slag [1] [2] [3] as a byproduct. It is used commercially as a form of waste ...
The first US incinerator was built in 1885 on Governors Island in New York, New York. [2] The first waste incinerator in Denmark was built in 1903 in Frederiksberg. [3] The first facility in the Czech Republic was built in 1905 in Brno. [4] Gasification and pyrolysis processes have been known and used for centuries and for coal as early as the ...

Pyrolysis occurs during the incineration of trash, potentially generating volatiles that are toxic or contribute to air pollution if not completely burned. Laboratory or industrial equipment sometimes gets fouled by carbonaceous residues that result from coking , the pyrolysis of organic products that come into contact with hot surfaces.
The waste is then stored until it is time for burning. A few plants use gasification, but most combust the waste directly because it is a mature, efficient technology. The waste can be added to the boiler continuously or in batches, depending on the design of the plant. In terms of volume, waste-to-energy plants incinerate 80 to 90 percent of ...
Waste gasification has several advantages over incineration: The necessary extensive flue gas cleaning may be performed on the syngas instead of the much larger volume of flue gas after combustion. Electric power may be generated in engines and gas turbines , which are much cheaper and more efficient than the steam cycle used in incineration.
Biomass (in the context of energy generation) is matter from recently living (but now dead) organisms which is used for bioenergy production. There are variations in how such biomass for energy is defined, e.g. only from plants, [8] or from plants and algae, [9] or from plants and animals. [10]
Incineration is a waste treatment process that involves the combustion of substances contained in waste materials. [1] Industrial plants for waste incineration are commonly referred to as waste-to-energy facilities. Incineration and other high-temperature waste treatment systems are described as "thermal treatment".
