Gamifying waste management.
A points-based household waste-segregation programme co-designed with the Municipal Council of Jaffna. Households earn weekly points for properly separated waste, redeemable at twelve participating neighbourhood shops; schools compete in a monthly clean-up league with a small trophy that travels between principals' offices. The app is SMS-first for families without smartphones — paper sticker on the bin, three-digit code to text in. We have not, so far, called this "empowerment"; we have called it taking the rubbish out, which it is.
