The Guardian reports on a Barter Market in Mexico where, in return for donating plastic bottles for recycling, people receive tomatoes, onions and a cabbage, for example.

“The objective is that people learn to separate, store and value the waste they produce,” said Liliana Balcazar of the city’s environment ministry, which runs the market, usually in a central park, although it moves to different locations around the capital every other month. She said the market received about 12 tonnes of rubbish each time. “It was always popular,” she said, “but now it is overflowing.”
