Yi Jie and her family live next to a primitive recycling plant. Her world consists of mountains of plastic waste from Europe, the United States and Asia.
Plastic China informs us that China is the world’s largest importer of waste. Toxic water run-off from the factory is what Jie uses to wet her hair before she brushes it as seen in the film. Plastic partials are forced through a machine that turns the plastic into a gross, grey sludge before it is transformed into small grey pellets.
