Plastics: What's Recyclable, What Becomes Trash — And Why - NPR Visuals

To recycle is to be an actor in a global scrap trade. Each year that trade is infused with hundreds of millions of tons of plastic material. In 2018, China stopped taking most plastic waste from the U.S. So now the whole plastics industrial chain — from the oil industry to recyclers — is under pressure to figure out what to do with it.

Plastic Pollution - Our World in Data

Plastic waste generation is strongly influenced by primary plastic use, but also the product lifetime. Packaging, for example, has a very short 'in-use' lifetime (typically around 6 months or less).
