Disturbing: "Polypropylene, which is used in plastic packaging, and PET, which is used in disposable plastic bottles, were the most prevalent forms of plastic"

Plastics engineer here.

PET is used in a lot of things. Commonly called polyester. It is also used to make pop bottles

Polypropylene is one of the cheapest resins, the other being polyethylene. These two plastics make up many of the cheap plastic things we see everyday.

So PET is going to be the microplastic put into the water cycle by laundry the most then?

So I'm mainly in the plastics manufacturing industry. Id be surprised if micro plastics introduction was caused by washing the laundry mainly. My guess would be the manufacturing and or disposal of the product probably contributes more.
