SOLID WASTE MANEGEMENT :
Solid is valuable resource, if we use it properly.Today the world is facing another problem of pollution as solid waste pollution, which has major role in pollution of soil and water. In human society, solid waste is a serios issue and has a linkage with economic growth, enviromental degredtion and health hazards; polluting air, water and land destruction of human habit.

Our solid waste management generation & management practices are very poor. Major cities like Mumbai generate solid waste up to 5000 tonnes per day. You know that on 26 july 2005 heavy floods occurred in Mumbai. One of major cause of floods was mismanagement of solid waste. Drainage lines were choked due to solid waste and plastic carrybags.

3 Rs are important in waste management.
1. Reduce, 2) Reuse, 3) Recycle.
1. Reduce solid waste at source means using less paper and less use of plastic carry bags..
2. Reuse means making manure out of decomposable waste, making note-books out of unused papers Recycle means separating plastic, metals, rubber, glass and sending it to recycling for manufacture of other products.
