- The burnable leftovers from the 10 upcoming waste processing plants in the city,will be given to cement companies, for use as fuel and the biodegradable waste as manure to farmers.
- The joint initiative taken up by the Karnataka State Pollution Control Board (KSPCB) and Karnataka Urban Infrastructure Development & Finance Corporation (KUIDFC),has had agreements with cement manufacturers such as ACC, Rajashree, Vasavadatta, Vikat Sagar and Ultratech in Kalaburagi district.
RDF and Fossil fuels
- The burnable refuse derived fuel (RDF), can be used only in a plant where the kiln temperature is above 1000 degree celsius, and cement companies come in this category .
- Plastic-like material is a good alternative for fossil fuel,as it can replace up to 20 percent of fossil fuel in terms of energy.
- The idea to use RDF instead of fossil fuel in cement plants was first conceived by Hasiru Dala, a Bengaluru-based non profit working on waste management.
- Hairu Dala, has provided 100 tonne of burnable waste to Zuari Cements plant in Andhra Pradesh in the past two months.
- Nalini Shekar, founder of Hasiru Dala, said the material was not sold to the cement plant for a price, but Zuari paid for packaging and transportation.
- Households have been asked to segregate waste,and hand it to garbage collectors to make the process easier.
- Also collectors were asked,to insist on the segregation.
- Besides the six plants coming up at Chikka Nagamangala, Kammanahalli, Seegehalli, Lingadheeranahalli, Subbannapalya and Dodda Bidarakallu on city outskirts, the one at Karnataka Compost Development Corporation has been upgraded.
- Another plant will be coming up in Doddaballapur, and sites for two more plants are being identified now.
- The plants can handle 200-250 tonne garbage each everyday .
