Anaerobic WTE Plant for Community Development

[box type=”shadow” ]Presently, ULBs spend `800-2000 per tonne for transportation of waste to landfill area. According to EY/ FICCI/ ASSOSM statistics, India generates 55 million tonnes of MSW per annum, out of which food waste worth `50,000Crore is going to landfills. The loss can be turned to a profitable business by establishing 50,000 decentralised ‘community development waste to energy plants’ across the country. The question is what should be the right technology to pave way forward? Er. P Velu Nath, a waste management expert puts forth his wellresearched methods of waste management and turning waste into energy.[/box]

IN GERMANY, 860 “community development WTE plants” were operational in 2006. In our country, the numbers should have been more but it is actually very few. While the Prime Minister has envisaged the installation of Community WTE plants as part of his vision and mission,there are huge benefits (tangible & intangible) for ULBs. Over 500 cities have the capacity to install “decentralized community development WTE plants” presently.

As per MSW chart, street sweeping waste is 1%, Home/ Residential waste 68%, hotel & restaurant waste 12%, commercial waste 14% and industries / market 6%, as tabulated by “CMDA”. Total waste generated is 5,000mts/day (during 2013- 2014 statistics). The solution for “CMDA” on ward/ zone wise community development WTE plants with all technical details are tabulated.

Homes & Residential – 68% / 3400 tonnes: All homes can install a ‘kitchen garbage food waste disposer” small device like “mixer / grinder” which can crush & flush them and through drainage. 30% of their home waste can be at source disposed, balance 32% 1292 tonnes can be discharged to “community waste collection bins” as “MSW”.

Homes & Restaurants – 12% / 600 tonnes: Hotels & restaurants can also use the bigger size “Garbage Food waste disposer” or community development WTE plants” which are now available in container type also. This can save costly space and other capex (A/C equipment) & opex (electrical expense) too. This “community development WTE plants” generates Bio-gas/ Electricity / Bio-fertilizer which is a revenue generator and environmental safety. As per the current waste composition, a maximum of 10% can be sonsumed through WTE and balance 2% i.e.12 tonnes can be settled to “community collection bill as “MSW”.

Commercial & Complexes – 14% / 700 tonnes: This can be reduced to 4% i.e. 28 tonnes.

Industrial and Markets – 6% – 300 tonnes: Post WTE, only 1% 3 tonnes remains to be counted as MSW

Thus, after installing the community development WTE plants, community collection bins will have 1292+12+28+3 = 1335 tonnes to dispose off to the landfill.

Garbage food waste disposer cum Community development WTE plants must be made mandatory for all, as are in foreign countries like USA/ UK/ Singapore other countries. This is instrumental in making clean India 2019 possible.
