Frustrated by unreliable waste collection, several high-rise apartment complexes in Kochi, India, are turning lemons into lemonade – or more accurately, biogas. Using technology pioneered in Europe, the buildings feature onsite biogas plants that process residents’ food scraps and other biodegradable waste into energy. While the resulting electricity from one 24-flat building currently using the technology is not enough to power the entire complex, it is powering the cooking appliances for the onsite security staff.

So every time residents see their doorman eating a microwave burrito, they can take pride in knowing that the discarded remains of their gourmet meal made it happen.
