4 Different Thermal Treatment of Waste

Thermal treatment of waste is a developing and exciting new area of waste treatment.  These  technologies are described in brief  below to get a general idea about the process, so take a peek

Thermal Treatment of Waste


Incineration of waste
Well-established and proven technology, while ongoing development is continuing  to improve the technology. Mass burn, modular and refuse-derived full incinerators are widely used in Europe and the USA. Fluidized bed incineration of MSW has been most extensively used in Japan.  This entails burning the solid waste particles in a hot bed of ash, sand and limestone with jets of air then blown into the bed to give combustion.
Pyrolysis of waste
Pyrolysis can be used to produce liquid fuels similar to diesel from plastic waste.  It is also used in the seperation of solids in tires removing the steel and carbon black leaving liquid and gaseous compounds that can be reused for fuel.  This is not widely used as tests are being carried out on the safety of this technology
Plasma thermal treatment of waste
Plasma thermal treatment is in initial stages of development and has limited treatment capacity and high treatment costs. However, may be effective technology to treat waste containing various metals, PCBs, dioxins etc.  It is becoming increasingly popular due to the problems with waste disposal.  This technology opens the doors to producing many by-products of waste.
Thermal gasification of waste
Proven technology for biomass, wood, sewage, sludge etc. Mostly at development stage for mixed solid waste stream.  This technology involves two stages. The first stage is the gasification of the waste in a primary chamber to produce a synthetic gas.  The second stage oxidises the synthetic gas at a high temperature.
