Global Warming #2: the Indian Landfill Connection
Segregating the recyclable waste. The organic waste. All that is a good thing, no doubt. At least the organic waste doesn’t do any harm, I used to think. Unlike plastics and other wastes, at least nature has microbes and processes to break down organic waste.
I realized I
wasn’t entirely correct, as I read Spoorthy Raman’s article. The problem lies in the quantity of organic waste we
generate, which is then compounded by how landfills operate in India:
“As
new layers of waste push older layers down in a landfill, the supply of oxygen
is cut off from the lower layers of organic waste, forcing it to undergo
anaerobic decomposition.”
This anaerobic
decomposition releases a cocktail of gases, two of which (methane and carbon
dioxide) are “infamous greenhouse gases that warm up our planet and cause
climate change”. India’s share of methane generation (as a fraction of its
greenhouse gases generation) is much higher than the global average.
It’s sad that our contribution to global warming isn’t limited to the usual suspects – coal and fossil fuels – but is also based on how our landfills are overloaded. It just one more item to the list of things that need to change in our steps against global warming…
