(Dilip Biswas)Chairman, CPCBC entral Pollution Control [9/6/2012 11:04:24 AM]MUNICIPAL SOLID WASTESGROWING PROBLEMS :Solid wastes generated by domestic, commercial and industrial activities are often indiscriminately management of such wastes leads to serious environmental problems. The problems are already acute incities and towns, as the disposal facilities are not keeping pace with the quantum of waste being generated.

5 It isvery common to find large heaps of garbage in disorganized manner at every nook and corner of the cities. In sanitary method being adopted for disposal of solid wastes is a serious health concern. Particularly, during rainyseason, run-off and high humid conditions increase the health hazards. The landfill sites, which are not wellmaintained, are prone to groundwater contamination due to leachate percolation. Open dumping of garbage servesas breeding ground for disease vectors such as flies, mosquitoes, cockroaches, rats and other pests.

6 High risks of spreading diseases like typhoid, cholera, dysentery, yellow fever, encephalitis, plague and dengue fevermay not be ruled out. There are three major steps involved in the management of garbage viz. collection,transportation and disposal (CTD). The collection methods currently adopted by the civic authorities are primitive and lacking in specific standards orguidelines, which are required to be laid for designing and sitting of collection of garbage is carried out using old outdated trucks, tippers and refuse collectors.

7 Inadequacy oftransportation fleet and frequent breakdown of vehicles are the major hardship in proper collection of of municipal solid wastes is generally done through landfilling. Most of the cities have acquired land forlandfilling years ago, and now these sites are over-used. Acquisition of the new sites is a tough task for to ContentCentral Pollution Control [9/6/2012 11:04:25 AM]MUNICIPAL SOLID WASTESCHARACTERISTICS OF GARBAGE :Quantity It is estimated that solid waste generated in small, medium and large cities and towns is about kg, kgand kg per capita per day respectively.

8 CPCB sponsored a survey to ascertain the status of municipal solid waste disposal in metro cities, Class-I cities andClass-II towns of India. The survey was conducted by the Environment Protection Training Research Institute(EPTRI), Hyderabad. As per the survey, the quantities of municipal solid wastes generation in metro cities arepresented in Table1.

10 Current practices in residential areas for collectionof garbage differ from city to city and even within the city. Door to door collection is not widely practiced. A fewresidential societies hire private scavenging staff for door-to-door collection of solid waste. The local authorities do not have proper provision to collect waste from narrow residential and commercial lanes, andin areas with high traffic. The slums and squatters in cities also create in sanitary conditions.
