Question

Capping is the method of

A)compacting waste and sealing it in a container.
B)piling waste into a hill at surface level and covering with clay.
C)burying waste and covering with soil.
D)laying soil over the surface of a landfill and planting vegetation.

Answer 1

Capping refers to the process of covering a landfill with soil and planting vegetation on top to protect and isolate the buried waste. It is related to the primary methods of waste disposal which include landfill and incineration.

Step-by-step explanation:

Capping is a method associated with waste disposal techniques, most commonly applied in the management of landfills. Specifically, capping refers to the process of laying soil over the surface of a landfill and planting vegetation, which serves several purposes such as preventing the influx of water that could create leachate problems, controlling gas migration, and minimizing erosion. Two primary methods of waste disposal are landfill and incineration. Landfilling involves burying waste, which is eventually covered with soil, and possibly a layer of clay, to contain and isolate it from the environment. Incineration is the process of burning waste at high temperatures, reducing its volume and sometimes generating energy, but it can contribute to air pollution if not managed properly.
