Solution to Kerala’s Solid Waste Disposal Problem?
Join Facebook Page of Scaling New Heights Blog
The most stupendous and bizzare issue confronting Kerala (and most of India) today and Trivandrum in particular are the mountains of highly hazardous and dangerous community wastes at Vilappilsala and in and around Trivandrum which have become public waste dumping sites. These have grown to such enormous size over years, not overnight, due to reckless arrogant attitude and lack of scientific temper and approach. These sites have been assigned erroneous misleading nomenclature as “Waste Treatment Plants and Factories”. Of course one can call them Factories/ Industries enticing tourists like rats, flies, mosquitoes, dogs, vultures who in return gift us regularly perennially with epidemics of hepatitis, Dengue Hemorrhagic fever, rat fever, typhoid fevers, diarrhea, dysentery, cholera, tuberculosis, and, other disorders damaging vital organs due to consumption of toxins through contaminated air, water and soil.
Kerala government and the Trivandrum Corporation are in a fix to find a solution to this problem. Here is a digester developed by Dr Thankamani, Professor and Head, Department of Biotechnology that can treat solid waste generated in hotels and kitchens and produce gas that can be used for cooking. A full scale plant designed by Murali V Iyer has started operational in Angamali. The plant has two reactors with capacity 2000 liters and 8000 liters that uses of waste from hotel and market waste as feed. It produces 600-800 liters of bio-gas per 10 kg of feed. The total biogas production from both the digesters is approximately over 30,000 liters per day!
It is heartening to note that lot of hotels have come forward to implement this technology. Below are few photos of this plant.
