Solid Wastes
- Solid wastes refer to everything that goes out in trash.
- Municipal solid wastes are wastes from homes, offices, stores, schools, hospitals, etc., that are collected and disposed of by the municipality.
- The municipal solid wastes generally comprise paper, food wastes, plastics, glass, metals, rubber, leather, textile, etc.
- Burning reduces the volume of the wastes, although it is generally not burnt to completion and open dumps often serve as the breeding ground for rats and flies.
- Sanitary landfills were adopted as the substitute for open-burning dumps.
- In a sanitary landfill, wastes are dumped in a depression or trench after compaction, and covered with dirt everyday.
- Landfills are also not really much of a solution since the amount of garbage generation especially in the metros has increased so much that these sites are getting filled too.
- Also there is danger of seepage of chemicals, etc., from these landfills polluting the underground water resources.
- All waste that we generate can be categorised into three types – biodegradable, recyclable and the non-biodegradable.
- It is important that all garbage generated is sorted. What can be reused or recycled separated out; our kabadiwalas and rag-pickers do a great job of separation of materials for recycling.
- The biodegradable materials can be put into deep pits in the ground and be left for natural breakdown.
- That leaves only the non-biodegradable to be disposed of.
- The need to reduce our garbage generation should be a prime goal, instead, we are increasing the use of non-biodegradable products.
- State Governments across the country are trying to push for reduction in use of plastics and use of eco-friendly packaging.
