India generates 1,50,650 MTS, per day MSW which can generation about 5000MW Electricity. To avoid the investment issue at large, the Community development WTE plants can be adopted as part of new entrepreneurship programme of engineering colleges / IITS / Universities. Among these, IIT Mumbai and BARC (Babha Atomic Energy Center) have already installed some plants in Chennai. This should be encaourages as sustainable business for them, with risk involved.
The business is sustainable in many ways, first and foremost there is no dearth of raw material supply chain at any point of time. There is no cost involvement, as the raw material is waste. Further, the entire business can be covered under CSR activities and hence unnecessary tax can be avoided.
Having said all the biggest result to count for is the image upgradation of the society with no waste lying along the roadside.
This business makes perfect sense for new entrepreneurs.
For our Indian environment and socio economic we have chosen “AD” anaerobic digestion. This can be designed depending upon quantum of waste generated in each ward/ zone for small community development energy form waste plant form `1 crore to 25 crores. This may be suitable for new entrepreneurship application. With regard to zone wise plants may be suitable for “CSR” 8600 Corporates houses from Rs8 crore to 25 crores.
Therefore, individual new entrepreneurship from colleges/ university can choose “ward size” community development WTE plants for their sustainability.
With regards to zone wise “community development WTE plants” can be under taken by corporate group “CSR” spending areas. Plant cost ranges from Rs8 crore to 20 crores. Power generation per day 850KW to meet their each zones employment potential would be 3000 local community people.
Community development WTE plants provides employment potential / poverty alleviation by employing rag-pickers/ scavengers by giving good skilled education training method “Community development WTE plants” is environmentally sustainable by development and socio economics plant programme corporates houses are directly helping global warming & climate changes.
For example, “NLC” chairman Mr. Surender Mohan has proposed to allot `41 crores for “CSR” activities in 2014-2015 “NLC” can sponsor 2 to 3 zones of “Community development WTE plants” as a first sponsor for Tamilnadu.
Major comparison of WTE technologies are
Before implanting the above technologies municipal solid waste (MSW) should be segregated as “biodegradable” and “nonbiodegradable” biodegradable waste shall go through above technologies for energy generations. As per Europeans union guide lines, biodegradable should be diverted from landfill to energy conversion plants where electrical energy/ biomethane (bio-gas) and the residue out of the above process shall be organic manner for soil.
This (WTE) waste to energy plants may be decentralized (ie) small scale community development scale to meet the needs to localized energy requirement of bio-methane for domestic and transportation fuel.
The energy recovered from (MS) is called renewable energy source.
Before, selecting the technology, we should analyses or compare the suitability of the technology depending upon the “ENVIONMENTAL” impact to the particular area. Now a days the economics for investing in the size or scale of the plants depends on raw materials (MSW) availability with quality and source of funding availability also.
Take for instance, Greater Chennai (Tamilnadu) is generating 5000 tonnes of (MSW) per day. Entire 5000 tonnes to be brought to one place and put up a single massive (WTE) plant is having some advantage and disadvantage on economical & social front are to the analyzed.
When one single massive plant is envisaged heavy funding, heavy land scape and economics risks are more. When the same 5000 tonnes/day is divided by 4 north, south, east and west zones, risks are limited and energy generated could be utilized to the same local population requirement and frequent power cuts could be avoided transportation of (MSW) to a long distance is also avoided. Depending upon the size of the plants, the (AD) anaerobic digestion (WTE) plants can be environmentally and economically safe and risk factor is less when compared to others technology.
Therefore, to meet local demands of electrical energy / transportation fuel & domestic bio-methane (instead of LPG) to housewife, the residue out of this (WTE) process, bio manure (organic) for organic agriculture produce. Now a days the costs of LPG / LNG gases are day by day increasing to sky level.
