Which of the following statements most accurately describes pyrolysis in solid waste management?
Thermal decomposition of organic materials at high temperature in the absence of oxygen
Pyrolysis is a waste treatment process in which organic materials are broken down by heat at high temperatures while oxygen is deliberately excluded.
Because there is no oxygen present, the process cannot involve combustion (which requires oxygen) or aerobic biological degradation (which requires living microorganisms and oxygen); instead, the material thermally decomposes into simpler compounds, gases, and residual char.
This distinguishes pyrolysis clearly from incineration, composting, and other oxygen-dependent waste treatment methods.
