Abstract: Rapid urbanization and industrialization have moved people to cities and led to generation of wastes in abundant manner. Globally average waste generation have reached 1.2 kg per capita per day while for India is 0.1 kg -0.5 kg /capita /day. In Indian context more than 55 million tons of MSW is generated per year; the yearly increase is estimated to be about 5%. The estimated annual increase in per capita waste generation is about 1.33 % per year. Issue to dispose such amount of waste becomes challenge for municipal corporations. In absence of proper waste handling facilities most of the wastes dumped openly, resulting contamination with water bodies, land pollution and generation of hazardous gases like Methane. This hurdle can be mitigated by adopting suitable Waste to energy technologies, is best renewable option for treating wastes before disposal. There are many technologies available which can be utilized for extraction of energy from wastes. Technologies for W to E are: Incineration, gasification, pyrolysis, Refuse-derived fuel (RDF) & Biomethanation. India has adopted two commercially viable WtE technology: Biomethanation and RDF. RDF based technology becoming a popular source of clean energy. As per MSW rules, 2000 biodegradable waste cannot be disposed to landfills sites. So an integrated waste management approach can reduce the burden of landfills. Optimization of resources helps in waste minimization. Approach towards zero waste goal might be the ultimate aim of any WtE facility. Timarpur Okhla Waste Management Company Pvt. Ltd. (TOWMCPL) is India’s only commercially successful W to E project with having 16 MW capacity. It consumes average 1/3rd i.e. 2000 TPD -2100 TPD MSW of Delhi in 3 specially designed boilers. In this report attempts to design suitable systems by adopting the concept of 4R-Reduce, Reuse, Recycle, Recover to ensure safe disposal of waste and attainment of Zero Waste aim.
