Mamallapuram, Tamil Nadu

Mamallapuram is a UNESCO World Heritage site, home to some of the most magnificent temples and other historic monuments built between the 7th and 9th centuries. A very popular tourist destination, the town attracts thousands of national and international tourists. On an average 3 metric tons of food waste is generated per day from the hotels in Mamallapuram.
In association with the Mamallapuram Town Panchayat we installed a bio-methanation plant to efficiently manage bio-degradable waste, especially food waste, generated by the hotels in Mamallapuram.
A 100 cu.m bio-methanation plant with a capacity of handling 500 to 800 kg of food waste every day has been installed. The food waste is converted to methane which is in turn converted to electricity. A 12.5 KVA generator which runs exclusively on biogas has also been installed. The generator has a capacity to produce electricity at 10 KW per hour.
The bio-methanation plant in Mamallapuram is a model project that demonstrates the reduced dependency on conventional energy sources. It serves as a demonstration unit for other local bodies to replicate for resource recovery and proper management of organic waste, particularly food waste.
