How plasma technology is being used in waste treatment?

How plasma technology is being used in waste treatment?

plasma arc gasification (PAG), waste-treatment technology that uses a combination of electricity and high temperatures to turn municipal waste (garbage or trash) into usable by-products without combustion (burning). The process can reduce the volume of waste sent to landfills and generate electricity.

What is gasification in solid waste management?

Gasification is a unique process that transforms a carbon-based material, such as MSW or biomass, into other forms of energy without actually burning it. Instead, gasification converts the solid and liquid waste materials into a gas through a chemical reaction.

What is the need of gasification?

Gasification is a process that converts organic or fossil-based carbonaceous materials at high temperatures (>700°C), without combustion, with a controlled amount of oxygen and/or steam into carbon monoxide, hydrogen, and carbon dioxide.

Does plasma gasification is another form of waste management?

It is used commercially as a form of waste treatment and has been tested for the gasification of refuse-derived fuel, biomass, industrial waste, hazardous waste, and solid hydrocarbons, such as coal, oil sands, petcoke and oil shale.

What is gasification technology?

Gasification is a technological process that can convert any carbonaceous (carbon-based) raw material such as coal into fuel gas, also known as synthesis gas (syngas for short). Syngas is so called because of its history as an intermediate in the production of synthetic natural gas.

What are main products from waste gasification process?

The main gasification syngas product contains carbon monoxide, hydrogen, and methane. Generally, the gas generated from gasification has a net calorific value (NCV) of 4–10 MJ/Nm3.

What is plasma gasification as a source for solid waste management?

Plasma gasification is an emerging technology which can process landfill waste to extract commodity recyclables and convert carbon-based materials into fuels. It can form an integral component in a system to achieve zero-waste and produce renewable fuels, whilst caring for the environment.

What are the benefits of plasma gasification?

Plasma Gasification and its Potential Advantages Greater feed flexibility enabling coal, coal fines, mining waste, lignite, and other opportunity fuels (e.g., biomass and MSW) to be used as fuel without the need for pulverizing. Air blown and thus an oxygen plant is not required.
