More Brazilian films about (and around) landfills:
Lixo Extraordinário (Waste Land) (2010)
On the outskirts of Rio de Janeiro is Jardim Gramacho, the world's largest landfill, where men and women sift through garbage for a living. Artist Vik Muniz produces portraits of the workers and learns about their lives.
Estamira (2004)
Documentary about Estamira, a 63-year-old woman who's been working for over 20 years at a landfill in Rio de Janeiro. Schizophrenic, but very charismatic, she's the leader of a small community of old people living off garbage and has a very lyrical and philosophical attitude towards life.
And a fictional one, based on the book by Andy Mulligan
Trash (2014)
Set in Brazil, three kids who make a discovery in a garbage dump soon find themselves running from the cops and trying to right a terrible wrong.
