Solid waste is everything that goes to trash. It includes wastes from home, offices, stores, schools, hospitals etc. Wastes are collected and disposed by municipality. Municipal solid waste generally consists of paper, food, plastic, glass, metals, rubber, leather, textile etc;Burning reduces volume of the waste. Generally, it is not burnt to completion. So open dumps become breeding ground for rats and flies.

Sanitary landfills are substitute for open burning dumps. Here wastes are dumped in depression or trench. Everyday wastes are added to this pit. Landfills get filled very soon especially in metro cities. The amount of garbage generated is too high. In addition to this, there is a danger of chemicals percolating and reaching down to ground water and contaminate this water source. All wastes can be categorised in three types-

1. Bio degradable

2. Recyclable

3. Non bio degradable

Our rag pickers and kabadiwallahs do a great job of separation of materials for recycling. Primary goal of all citizens should be to reduce generation of waste.

The biodegradable materials can be put into deep pits in the ground and left for natural degradation. Non biodegradable wastes have to be disposed off.

Hospitals generate harmful waste that contains disinfectants, harmful chemicals and also pathogenic microorganisms.Such wastes require careful treatment and disposal. You are aware of colour code for disposal of biomedical waste.

Irreparable computers and other electronic goods as well as electrical waste are known as e wastes. They are buried in landfills or are completely burnt. Major part of e waste generated by developed countries are exported to developing countries like China, India and Pakistan. During recycling process of this waste, metals like copper, iron, silicon, nickel and gold are recovered. Developed countries have facilities for recycling of e waste. In developing countries, manual participation is involved. So, workers are exposed to toxic substances from e waste. Treatment of e waste should be carried out in environment friendly manner.You have already studied about radioactive pollution.
