A UK app has created a special cash lottery for anyone picking up and binning litter.

Taking the idea of one man's trash being another man's treasure to new lengths, the "omni processor" plant takes literal human waste and turns it into valuable goods - including electricity and clean drinking water.

First published on Caleidoscope. The issue of waste management in India is a much debated topic which needs no introduction. Everyday, large space is dedicated in the media to highlight the problems of urban waste. Politicians often use it as a talking point, while commoners make it a point to crib about it. Meanwhile, as tons of solid waste continues to pile up in the outskirts of cities, nothing seems to happen on finding a permanent solution to this everyday problem. It is hard to believe that a developing country like India which suffers from severe resource crunch in almost all natural resources, can afford to create such enormous piles of waste.

A team of anonymous do-gooders are transforming the rubbish-laden areas of Bangalore in an effort to change attitudes about waste disposal and promote a sense of civic duty in all citizens.
