Waste Generation and Management
Original Khojo Papers practice question — not from a past board paper.
A sanitary landfill is a prepared site with an impermeable lining, in which waste is spread in layers, compacted and covered with earth each day, with the leachate collected and treated and the gas vented or used. An open dump is simply waste left in the open, where it breeds flies and rats, catches fire and lets leachate soak into the groundwater.
No citable source has been recorded for this record. Treat it as practice material, not as fact.
A landfill must also be sited away from settlements and water bodies.
