Many plastic items that Americans put in their recycling bins aren’t being recycled at all, according to a major new survey of hundreds of recycling facilities across the US.

The research, conducted by Greenpeace and released on Tuesday, found that out of 367 recycling recovery facilities surveyed none could process coffee pods, fewer than 15% accepted plastic clamshells – such as those used to package fruit, salad or baked goods – and only a tiny percentage took plates, cups, bags and trays.

The findings confirm the results of a Guardian investigation last year, which revealed that numerous types of plastics are being sent straight to landfill in the wake of China’s crackdown on US recycling exports. Greenpeace’s findings also suggest that numerous products labeled as recyclable in fact have virtually no market as new products.

While the report found there is still a strong recycling market for bottles and jugs labeled #1 or #2, such as plastic water bottles and milk containers, the pipeline has bottomed out for many plastics labelled #3-7, which fall into a category dubbed “mixed plastics”. While often marketed by brands as recyclable, these plastics are hard for recyclers to repurpose and are often landfilled, causing confusion for consumers.
