Abstract:
Waste is defined as any material that is not useful and represents no economic value to its owner, the waste generator. Depending on the physical state of waste, they are categorized as solid, liquid and gaseous. Waste Management involves planning, financing, construction and operation of facilities for the collection, transportation, recycling and final disposition of the waste. Every five years the waste generated is rising by 1 million tons, In case it is not disposed within a stipulated time, it tends to create serious health hazards and reflects negatively on the infrastructure. The existing garbage disposal system, where it is collected from the streets, houses and other establishments once a day, is not able to effectively manage the waste generated, resulting in spill over on streets. Bangalore metropolitan city municipal council deployed concrete dustbins at every street corner to collect the garbage, engaged its labourers and vehicles to clear the trash. The municipal efforts did not pay any dividend and hence it had to eliminate the bins since residents would litter garbage around the bin once the bins were full. Consequently, concrete dustbins were replaced by the door- to-door garbage collection system, which was also ineffective in its implementation. The Indian National Capital Territory, Delhi is rapidly growing and so is its corresponding waste production. 85% of the city does not have a formal door-to-door trash pick-up system. The Municipal waste, which is not always properly segregated at the source, often ends up as mixed waste in the already overflowing landfills.
