The documentary featured in today's "Trailer of the Day" for the 2017 Sundance Film Festival will make you think twice about that margarine container you toss into the recycling bin.

In "Plastic China," director Jiu-liang Wang takes viewers a massive recycling facility in China, the biggest importer of plastic waste in the world. Wang profiles two people at opposite ends of the recycling plant's food chain: Yi-Jie, an 11-year-old girl who works there but dreams of one day attending school; and Kun, the facility's foreman, who has ambitions of wealth and fancy cars.

"Plastic China" will have its world premiere in the World Cinema Documentary competition of the 2017 Sundance Film Festival, and will be part of the festival's "The New Climate" initiative. It screens at the following times and venues:
