The process of transforming waste into energy or raw material for cement, lime, steel, glass or power generation units is called ‘co-processing waste’.
Did you know that the city generates around 3,500 tonnes of solid waste which could be recycled and transformed into energy or raw material for energy intensive industries? The process of transforming waste into energy or raw material for cement, lime, steel, glass or power generation units is called ‘co-processing waste’.
AS Sadashivaiah, chairman of the Karnataka State Pollution Control Board (KSPCB) admits that the investment for co-processing waste is huge.
However, there are people willing to take up the task, with a little support from the government. “Nearly 3,500 tonnes of solid waste are generated in Bangalore city each day, and it could be treated in keeping with the ‘zero-waste’ concept.
Despite several meetings that the KPSCB has had with the Bruhat Bangalore Mahangara Palike (BBMP), no steps have been taken to co-process solid waste. Municipal waste could be transformed into energy.
This, admittedly, takes huge investment, and many Singapore companies have expressed interest in setting up units, the government has to make space,” said Sadashivaiah
There is huge potential for generating energy and raw material for industry from the waste developed in the state. Karnataka has about 26,000 industries that have obtained consent for operation from the KSPCB. Almost all these industries generate co-processable waste.
Wastes from the transport sector like tyres, waste oil, and rejected material from the municipal solid waste management plants are co-processable. Guidelines were issued for co-processing by the Central Pollution Control Board in 2010.
On Thursday, a workshop was jointly organised by the KSPCB and GIZ (Deutsche Gesellschaft fur Internationale Zusammenarbeit, a German firm that works for international cooperation in different fields), ‘Co-processing in cement kilns, power plants and integrated iron and steel industry’.
It was aimed at bringing together those involved in the implementation of co-processing so that waste is better managed in the state.
Speaking at the workshop, Sadashivaiah said, “The state has 11 cement industries, 10 coal-based power industries and one integrated steel industry. KSPCB has issued authorisation to four cement industries for co-processing of hazardous waste, and even non-hazardous waste like old tyres and plastic waste.”
About municipal solid waste management, the chairman of the state’s pollution control board said that local bodies in the different cities ought to take initiative. “Till date, the BBMP has not taken any initiative to manage solid waste,” Sadashivaiah said.
