Pollachi: A training programme on Solid Waste Management for the presidents of village panchayats was organised at Pollachi Municipality recently

A release from the Municipal Commissioner, K.R. Selvaraj said that solid waste management scheme was being implemented successfully in Pollachi and a ban has been imposed on use of plastics below 20 microns.

Special arrangement has been made to collect the waste from hotels, kalyana mandapams, theatres and hospitals by collecting a service amount once in six months.

The waste was being collected from houses and segregated at source.

S. Kamaraj, Professor of Bio-Energy, Tamil Nadu Agricultural University in his inaugural address appealed to the corporations, municipalities and panchayats to come forward to generate electricity through anaerobic treatment of bio-degradable solid waste.

From the 800 tonnes of solid waste collected in Coimbatore city per day, it was possible to generate eight mega watts of power resulting in 700 lakh units of electricity production annually.

The annual income from electricity would be about Rs. 21 crore.

Similarly, from the Solid Waste Management of 60 tonnes collected from Pollachi Municipality it would be possible to operate 600 kw power plant with the annual production of 50 lakh units of electricity. The annual revenue from the electricity generation would be Rs 1.5 crore.

In addition to power generation, equal amount of income could also be generated through manure production from slurry coming out of biogas plants.

The maintenance of waste to power generation project through anaerobic digestion (biogas plant) could be economical, if maintained by the local youth groups like Self-Help Groups.

The investment for such projects could be recovered within two to three years. He also appealed the NGOs and SHGs to engage in such economically viable ventures. He also appealed to help reduce the emission of green house gases by anaerobic treatment of waste instead of normal burning.

The burning of waste emits a lot of green house gases which lead to global warming. Therefore the best option of energy generation without affecting the environment would be through anaerobic treatment. The existing waste water treatment systems were mostly aerobic.

The energy requirement for operating such systems was very high and thereby the system was becoming uneconomical.
