Show answer & explanation
Correct answer: B
Concept
Waste-treatment methods are distinguished by their governing process and the role of oxygen. Incineration is controlled oxidative combustion in a furnace, whereas pyrolysis is thermal decomposition with little or no oxygen.
Biological treatment such as composting decomposes suitable organic matter, while mechanical treatment such as pulverization only reduces particle size.
Application
The stem specifies burning hospital waste at a high temperature in the presence of air inside a properly constructed furnace. Those defining conditions describe incineration.
Contrast
Composting uses microbial decomposition of biodegradable organic matter rather than furnace combustion.
Pyrolysis uses heat in an oxygen-deficient or oxygen-free environment, so it is distinct from burning in air.
Pulverization is a mechanical size-reduction process and does not itself thermally destroy waste.
Result
Therefore, the described hospital-waste disposal method is incineration.
