Waste Land...

Waste Land chronicles Vik Muniz's journey to Jardim Gramacho, the world’s largest landfill, located on the outskirts of Rio de Janeiro. He collaborates with an eclectic band of catadores,or self-designated pickers of recyclable materials, and photographs these inspiring characters as they recycle their lives and society’s garbage. Walker gains incredible access to the entire process and, in doing so, offers stirring evidence of the transformative power of art and the dignity that can be found in personal determination.
