Waste to Energy: A Sustainable Solution to India’s Growing Waste Problem

India, like many other nations, is struggling with a serious waste management issue. Each year, the nation produces more than 62 million tonnes of solid waste, a number that is predicted to double by 2030. Inadequate waste management endangers the environment and jeopardizes public health. Waste to energy (WTE), however, is emerging as a workable solution to address the waste problem and produce renewable energy in the wake of rising sustainability awareness. In the WTE process, municipal solid waste (MSW) or biomass is burned to produce energy in the form of electricity or heat. The procedure entails sorting and separating the waste, then turning the organic material into a fuel source, like biogas, that is then used to power various devices.

The Indian government has taken several initiatives to promote WTE as a sustainable solution to the waste problem. The Swachh Bharat Mission, launched in 2014, aims to make India clean by eliminating open defecation and managing solid waste effectively. Under this mission, the government has allocated funds for the construction of WTE plants across the country. The Ministry of New and Renewable Energy (MNRE) has also launched a program to promote the use of renewable energy, including WTE.
