Solid Waste Management

Step 1: Understanding daily cover in MSW landfills.
Daily cover is the material placed over municipal solid waste at the end of each working day to control odour, pests, litter, fire hazards, and exposure to rain.
Step 2: Commonly used material.
Traditionally, a layer of soil is used as daily cover because it is easily available, economical, and effective in isolating waste from the environment.
Step 3: Analyzing the options.
(A) Compressed soil: Correct, as it is the standard material used for daily landfill cover.
(B) Geo-membrane: Used as liners or caps, not as daily cover.
(C) Geo-textile: Used for separation and filtration, not daily covering.
(D) Geo-composite: Used in engineered barriers, not routine daily cover.
Step 4: Conclusion.
The daily cover of MSW landfills generally consists of compressed soil.
