ways to combat solid waste
Sanitary landfills: In this method the
bottom of the landfill is covered with layers of sand and plastic so that the wastes
don’t percolate to ground water. Then the garbage are dumped and spread out in
layers and covered with clay, soil, gravel and soil.
Incineration: This method utilizes
burning of solid wastes at high
temperatures thereby reducing the volume of waste to a much lesser volume along
with reduction of weight and giving rise to ashes.
Recovery and Recycling: The main aim
is to reduce landfills and also reuse the discarded items.
Composting: Biodegradable waste
materials are used for this purpose, and the product of composting can be used
for agricultural purposes.
