problems of solid waste management

1. Seminar On PROBLEMS OF SOLID WASTE MANAGEMENT SESSION - 2018-19 PRESENTING BY- BINITA PRADHAN M.Sc. (RT)2 nd Semester DEPARTMENT OF RURAL TECHNOLOGY AND SOCIAL DEVELOPMENT G.G.V . , BILASPUR , (C.G.)

2. CONTENTS Sources of waste Magnitude of problems in India Definition Classification of waste Problems of storage of solid waste ,the source of generation Problems observed in the processing and recovery of solid waste.

3. What is waste? Any material which is not needed by the owner, producer or processor. It is something one does not want any more and want to throw away.

4. Classification :- Domestic waste Factory waste Waste from oil factory E-waste Construction waste Agricultural waste Food processing waste Bio- medical waste Nuclear waste

5. Magnitude of Problem in India Per capita waste generation increasing by 1.3% per annum . With urban population increasing between 3-3.5% per annum . Yearly increase in waste generation is around 5% annually . India produces 62 million tones of municipal solid waste annually . Per capita generation of waste varies from 200 gm to 600 gm per capita/day . Average generation rate at 0.4 kg per capita per day.

6. Collection efficiency ranges between 50 % to 90% of the solid waste generated. Urban Local Bodies spend around Rs.500/-to Rs.1500/- per ton on solid waste management of which, 60%-70% of the amount is on collection alone 20 %-30% on transportation Hardly any fund is spent on treatment and disposal of waste

7. PROBLEMS OF STORAGE OF SOLID WASTE , THE SOURCE Of GENERATION In most of the cities in India , the scientific and systematic storage of waste at source is not in practice . The waste is normally thrown in nearby vacant areas, government vacant land ,drains, streets etc . Because of waste thrown on the street the environment becomes ugly and unhygienic , so even in case of regular cleaning be Municipal Worker also , the city can not be kept clean for more than 2-3 hours .

8. At sources people generally don’t arrange to provide proper dustbins , in residential , institutional and commercial areas . In case of open drains and large drains passing across the city, people throw waste and these drains are clogged , width of large drains are reduced because of continuous dumping.

9. Problems observed in the processing and recovery of solid waste Generally in Indian cities the formal processing and recovery units are not established. Recovery and recyclable activities restricted to small and medium scrap dealer. Involvement of small children and old people employed for sorting and segregating waste. No protective clothing / consideration for rag-pickers/ scavengers. Generally in Indian cities financial implications of recovery and recycling has not been studied or consideration to use solid waste for the purpose of finance generation

10. Effects of waste if not managed wisely Affects our health Affects our socio-economic conditions Affects our coastal and marine environment Affects our climate

11. conclusion By this we can conclude that Solid Waste generated in our area is very hazardous and causes various types of pollution and also health diseases and our earth is getting depleted day by day. We should take some initiatives to manage the waste and follow three R’s(Reuse, Reduce,& Recycle).
