WTE can rid us of energy crisis and pollution problem
The escalating demand of energy in India, which is projected to be 448,000 MW by 2020, could lead to huge environmental damage if the current methods of energy production go on. On the one hand, there is this huge demand-supply gap and on the other hand is the fragile condition of environment. Well, there is a solution for this dilemma too. The Waste-to-Energy (WTE) production technology solves these two problems as it converts waste from landfill sites into energy and reduces greenhouse gas emissions too.
Recently, companies like Tata Power, GMR Energy, Maytas Infra Ltd., Ambuja Cements Ltd., Ramky Enviro Engineers et al showed their interest to invest in the Rs.175 crore WTE plant in New Delhi. This horde makes at-least one thing clear: this technology has got a lot of returns. This first-of-its-kind project in Delhi is aimed at generating about 16 MW of power from waste. The WTE uses waste as fuel instead of coal or gas to run the power plant. The waste undergoes intense mechanical & thermal processes to flush out the combustible elements. This Refuse-Derived Fuel (RDF) is further burnt in a boiler to generate power. However, capital investment in this project is very high compared to typical coal-powered plants. The investments stands at Rs.11 crores per MW compared to Rs.4 crores per MW required by coal plants. But then, this high investment is compensated by almost zero fuel cost.
On global scale, there are about 600 major projects that use landfill gas for energy generation. The WTE technology had also been successful in countries like Germany, where 65% of municipal waste in the form of landfill sites recover energy from landfill gas and in the UK, 40 such schemes are in place.
