Clean Energy Solution – What is Plasma Gasification?-bio-medical waste


Plasma Gasification Process (PGP) is a thermal process that involves the application of intense heat to waste materials in a completely closed, controlled, and oxygen-starved environment. This process converts waste materials into a clean synthetic gas and heat that can be used to generate electricity.

Is the Plasma Gasification Process (PGP) just another form of incineration?

No. The PGP system is a thermal process that takes place in an oxygen-starved environment. Because minimal oxygen is present, no burning occurs. By applying intense heat to waste material in the presence of small and controlled amounts of oxygen, the waste is broken down into its simplest molecules and then recombined into an energy rich synthetic gas. This process is far superior to incineration because no emissions are released into the atmosphere and the syngas produced is rich in energy and is an efficient fuel for creating electricity with gas engines or gas turbines

How clean is the Plasma Gasification Process (PGP)?

The Plasma Gasification Process is beyond compliance with the strictest Canadian or European environmental guidelines. The waste conversion process produces no air emissions, nothing is released into the ground, and all the products of the process are completely reusable. Electricity generation using the synthetic gas product is as clean as electricity generation using natural gas-the gold standard in clean energy.

What types of waste can be processed?

The PGP system can process any waste stream such as: MSW (Municipal Solid Waste), biomedical waste and spent potliner, a granular waste from aluminum smelting, biomass, oil shale, automobile fluff, lead contaminated soils, municipal sewage sludge, paint sludge, drum reconditioning sludge, organic petrochemical sludge, illicit drugs, high metal content waste, coal and MSW waste ashes, paper mill reject waste, fluorescent light ballasts, asbestos containing material, explosives industry waste, rubber tires and industrial hazardous wastes including PCBs and concentrated insecticides.

What are the products of PGP?

There are three products produced by PGP. The main product of the process is a synthetic gas produced when the volatile elements in the waste material are reduced to their base molecules. This gas is used to generate electricity by feeding it into the same type of gas engine used in the production of electricity from natural gas.

The second product of the process is heat which produces steam. The steam is collected and fed into the electricity generation process to improve its efficiency.

The third and final product of the process is a glass-like reusable solid (otherwise known as slag) that is produced when the non-volatile elements of the waste material decompose. As hard and clean as glass, this solid has a variety of uses such as a road or building material additive. The solid does not react with other elements and leaches less than the glass from a common soda bottle.

Is there a limit to the amount of waste which can be processed?

There is virtually no limit to the amount of waste which can be processed. The PGP system is particularly adaptable to designing total systems around a multiple processing string approach. The string size for waste streams such as MSW can be up to 200 metric tons per day with multiple plasma arc generator heating systems per string. The optimum string size for other types of waste is dictated by the characteristics of the waste itself.
