Here’s a good thing going to waste. Although it’s been three years since young K.B. Joy set up an eco friendly waste treatment plant that the Kodungallur municipality (Kerala) has no complains about, no other local body seems interested in installing it. “They were perhaps sceptical because I told them it would be free of cost. All I want is the bio-manure produced by the plant which I sell to farmers and earn enough for its maintenance,” he says.
