Waste generation is increasing day-by-day with the growth of population which directly affects the environment and economy. Organic municipal solid waste (MSW) and agriculture sectors contribute towards maximum waste generation in India. Thus, management of organic waste is very much essential with the increasing demand for energy. The present paper mainly focusses on reviewing waste to energy (WtE) potentials, its technologies, and the associated challenges. Different substrates are utilized through various technological options in India. Organic waste has good potential to attain sustainable energy yields with and without affecting the environment. A realistic scenario of WtE technologies and their challenges in line with the existing Indian condition is presented in this paper.
