Legacy waste
Also called: Dumpsite · Topic: Geographical Issues: Pollution, Urban Waste, Slums and Land Degradation · NCERT: Beyond NCERT
Meaning
Legacy waste is old garbage that has been piled up for years at open dumpsites without treatment. As it slowly rots, it gives off methane, a gas that warms the climate and can catch fire. Rainwater passing through the pile forms leachate, a toxic liquid that seeps into soil and groundwater. Swachh Bharat Mission-Urban 2.0 (2021) aims to clear these dumps by bio-mining. Bio-mining means digging up old waste, sorting it and recovering soil, plastics and other materials from it.
Example
The Ghazipur, Bhalswa and Okhla dumps in Delhi and the Deonar dump in Mumbai are huge legacy waste sites. They are known for fires and methane emissions.
Don't confuse with
- Sanitary landfill: a site built with protective linings to take only leftover waste. A legacy dump is an open, unlined pile of old mixed garbage.
