In Brazil, supermarket shopping bags are widely used as trash bags. So, we decided to use them as a media and we produced them with specific colors and instructions to show what kind of materials should be discarded in them: paper, plastic, metal or glass. So we transformed plastic shopping bags into an ally to help recycle rubbish. To further reduce the environmental impact, the bags are made of biodegradable material. The recycling bags were distributed in test Carrefour stores in São Paulo, Brazil.

The response was extremely positive, with a lot of coverage by the local media and in their own supermarkets. At the same time as Carrefour helped the environment, it has been recognized as an environmentally friendly company by its customers.
