Disposal of Municipal Solid Waste utilizing high temperature Plasma

Type:  Equipment
IPR Status:  Copyright
Secured In:  India

Effective utilization of high temperature (>3000 oC) Plasma arc forecofriendly disposal of municipal solid waste material generated on daily basis and generation of fuel gas containing predominantly CO and H2.

Salient Technical Competing Features: 

 Mechanized handling of waste to avoid health hazard to the associated workers
 Eco-friendly disposal of municipal solid waste through utilizing high temperature ionized gas /electric arc with significantly low level of toxin generation
 Large volume reduction, slag is 1/250th of the volume of processed solid waste
 Generation of fuel gas containing predominantly CO & H2
 Unique gas cleaning system to minimize the dust accumulation in the generated fuel gas
 Special design consideration to prevent leakage of gas from the system during regular operation
 Storing facility of generated fuel gas
 Energy harvesting from generated gases through generation of electricity
 Utility of slag as construction material

Environmental Consideration: 

Eco-friendly disposal with generation of fuel gas containing insignificant amount of toxin.
