India transforms waste into energy

India transforms waste into energy

There are large number of options and technologies available today—bio fuels like bio-ethanol-diesels, etc. and waste to energy like gobar gas and commercial bio gas

India intends to transform its waste into energy.

Therefore, NTPC Limited, India’s largest power generation company, has invited interested domestic and international developers to construct 100 waste-to-energy (WTE) facilities in the country under the Swatch Bharat Mission of the government of India.

Waste Power Purchase

The selected developers would be provided with land, a supply of waste, and support in getting regulatory clearances for speedy implementation. Also, power purchase agreements will be arranged for the developers.

There are large number of options and technologies available today—bio fuels like bio-ethanol-diesels, etc. and waste to energy like gobar gas and commercial bio gas (CBG), etc. There is an urgent need to understand the appropriate technologies available for decentralized production of energy (for domestic fuel, transportation and electricity generation) from sources like cow-dung, organic waste and vegetations. At the same time, promote the uses of the residues for organic manure instead of chemical fertilizers. Collectively these efforts can help to reduce the carbon foot print in the era of climate crisis.

300 tonnes a day

It’s not a few tonnes of waste that India wants to transform. The invited parties should be familiar transforming 300 tonnes or more per day. The tender is quite clear about the criteria.

  • developers having a track record of successful commercial operations of WTE with a capacity of 300 tonnes per day or more with at least two years of successful operations
  • The shortlisted companies would be empaneled for setting up the facilities for which a separate tender will be floated.

NTPC has already commenced work earlier this year on Badarpur WTE plant having capacity to process 400 tonnes of garbage from South Delhi Municipal Corporation. The plant entails an investment of Rs 300 crore ($47 million).

Recently, two UK-based companies GJ Nature Care & Energy (GJNCE) and GJ Eco Power (GJEP), specialized in converting waste to energy, proposed to invest Rs 1500 crore ($233 million) in several south Indian cities to set up WTE plants in the next five years with advanced technology.

500 MegaWatt Power

The Ministry of New and Renewable Energy has assessed the potential from waste generated from cities and towns in India to be approximately 500 megawatts of power, which can be further increased to 1075 megawatts by 2031 and 2780 megawatts by 2050.

States have been directed to procure all electricity generated from waste-to-energy projects without fail. This power procurement will also be counted towards the Renewable Purchase Obligation of power utilities. As of the 31st of July 2017, India had an operational waste-to-energy capacity of 287 megawatts, most of it in the off-grid segment.
