Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Solid waste treatment by pyrolysis involves
A
Autoclaving
B
Heating in presence of air
C
Heating in presence of acetic acid
D
Heating in absence of air
Explanation: 

Detailed explanation-1: -The plasma pyrolysis process involves very high temperatures in the absence or near absence of oxygen [90]. At such high temperatures, it transforms the solid waste particles to the syngas, other light hydrocarbons, and non-leachable solid residue.

Detailed explanation-2: -Pyrolysis is an endothermic process, which takes place in the absence of oxygen. Pyrolysis is an endothermic process, which takes place in the abundance of oxygen. Combustion is an exothermic process, which takes place in the absence of oxygen.

Detailed explanation-3: -Incineration is a waste treatment process that involves the combustion of substances contained in waste materials. Industrial plants for waste incineration are commonly referred to as waste-to-energy facilities.

Detailed explanation-4: -Pyrolysis, one of the thermochemical processes wherein the organic compounds (solid and liquid waste) present in CMW are disintegrated at high temperatures under anaerobic or low-oxygen conditions.
