Lucia Blasco investigates two very different ways of dealing with the growing problem of household waste.
In Paraguay, the Recycled Orchestra of Cateura is making music by salvaging material from the country's largest landfill, while the city of Linköping in Sweden is burning its rubbish to produce electricity and heating for its inhabitants.
About the documentary
Every year we produce over 2 billion tonnes of solid waste worldwide. Most of it ends up in dumps or landfills, or is thrown into the oceans, or is burned.
Only a small fraction is ever recycled. But are there other, more creative uses for all that rubbish?
To try and find some answers, BBC Mundo reporter Lucia Blasco visits Paraguay to meet the inspiring young musicians of the Recycled Orchestra of Cateura, whose instruments are made out of rubbish from the city's main landfill; and she travels to the city of Linköping in southern Sweden, where almost all the houses are heated by energy produced by incinerating waste.
