Hazardous wastes are created by almost any manufacturing process or industry. There are a myriad number of hazardous wastes that you don’t even realize are a menace to health, habitat, or the environment. Industries are also finding and deploying safe and eco-friendly hazardous waste disposal measures for their effective utilization and disposal. Besides reducing the production of waste material, another focus has been on the safe disposal of such waste. The gasification of municipal solid waste (MSW) can be done by using various processes to convert it into a fuel or another source of energy. 

Process

The MSW is pre-processed into a suitable feedstock material which is then oxidized at temperatures as high as 800˚ C. The bye-product generated is syngas which can be used as a fuel to run gas engines, gas turbines, etc. The gasification of MSW has resulted in lesser demand for land under waste management and it also reduces environmental pollution.

 

Equipment

The reactors or gasifiers are used to convert the MSW into useful by-products. There are fixed bed reactors that can be further categorized into downdraft and updraft designs. Another type is fluidized beds which may involve using a bubbling or circulating design for efficient gasification of MSW. 

 

Recent Technology

New technology such as plasma gasification, pure oxygen or hydrogen gasification, and thermal depolymerization have been developed which are more efficient and successful. 

 

Conclusion

It is safe to say that 

 

gasification of MSW 

is the need of time. The process is detail-oriented and must be carried out with adequate knowledge of the type of waste material and sustainable equipment.
