For decades, big petrochemical companies responsible for extracting and processing the fossil fuels that make plastics have egged on consumers, reassuring them that recycling was the answer to our trash crisis. Just last month, Royal Dutch Shell executive Hilary Mercer told The New York Times that the production of new plastics was not the problem contributing to millions of tons of plastic waste piling up in landfills and drifting in oceans. Instead, she suggested, the problem is one of improper waste disposal. Better recycling, she implied, is the solution.

“We passionately believe in recycling,” Mercer told the Times.

But plastic recycling is in trouble. Too much of the indestructible material exists in the world, more than our current recycling networks can handle.
