Waste Land is a 2010 documentary directed by Lucy Walker. The film documents two years of work of Brazilian contemporary modern artist Vik Muniz in creating art with the cooperation of garbage pickers working at Jardim Gramacho, one of the world's largest landfills, serving the metropolis of Rio de Janeiro in Brazil.
Together with people employed to pick out recyclable material from garbage, Muniz creates large-scale portraits that are sold at art auctions in London and exhibited at the Museum of Modern Art in São Paulo.
The film portrays the lives of the garbage pickers and their working conditions as well as Muniz's efforts to help them to gain recognition and better living conditions.
