In Brazil "catadores" are people who work for co-operatives and pick through trash for valuables to recycle.
Although co-operatives are key to the recycling system, only two per cent of Brazil’s domestic waste ends up being recycled. Sixty per cent of municipal Brazilian waste ends up in open-air landfills.
The government has made it mandatory for all states to have a sustainable trash plan by 2014 - and that is opening up new doors for creative business.
