Turn Bangalore waste into wealth: Scientist

Last September, Bruhat Bangalore Mahanaga Palike’s (BBMP) council members led by mayor SK Nataraj had visited the Bhaba Atomic Research Centre (BARC) in Mumbai to see the bio-methanisation technology. And on Monday, Barc scientist Dr Sharad Kale visited the BBMP to give a power-point presentation on ‘Nisargruna’ technology developed by them for decentralised processing of biodegradable waste.
During the presentation, Kale said environment awareness was poor among people and ideas just remained in books.
“Segregration of garbage must be taken up at the source level. But this thought remains in books. For we see piles of garbage getting loaded into trucks. This is a common scene in all major cities. We should gear up ourselves to protect earth. If we are a little careful, we can change the picture,” Kale said.
“If we don’t take up the initiative to manage garbage now, we need one more earth for filling the garbage. Think that each person requires 250 gm of food and 50 litres of water per day. How much he or she requires for a month? Life is going to be difficult if we do not change,” he warned.
Quoting Russian thinker and novelist Leo Tolstoy, he said “Everyone thinks of changing the world, but no one thinks of changing himself.”
“We should think that waste is not just waste but it is a wealth bank. We should decentralise garbage distribution and recycle waste ward-wise. Our main aim should be a society free of dumping yards. There will no land fill or minimal garbage for the landfill if we recycle garbage at the ward level. For one metric tonne of waste, we can produce 60 kg of manure and 10 metric cube of gas and light up streetlights for 10 hours,” he said.
The organic manure, which will be produced, will be free of weed, heavy metals and plastic compounds.
“The success of this plan depends on how the public gets involved in segregating waste. Every citizen has to participate. If we set up several decentralised plants, it will reduce the transportation cost of the corporation. The four ‘Rs’ we should follow are: Reduce, recycle, reuse and be responsible. We request citizens not to burn the resources and to save and recycle waste,” he said.
Mayor SK Nataraj said BBMP has floated a tender for setting up such units in 16 wards. The first unit will be set up at Aramane Nagar on April 25.
“Every year, the BBMP is spending `5 lakh for recycling five lakh tonnes of garbage,” he said.
