Data Sort: What’s at stake beyond PET and HDPE bottles

Most West Coast materials recovery facilities (MRFs) are not equipped to sort plastics beyond PET and HDPE bottles. This material is often referred to as 3-7, but it includes small rigid plastic of all resins, as well as missed PET and HDPE bottles. It is this mix that is struggling to find a market in the wake of National Sword. Though the 3-7 bottle and small rigid category makes up just 15 percent of all plastics collected, it carries significant economic implications.

Polypropylene (PP) is the largest component of these bales. Taking California as the West Coast example, not recycling PP translates to at least $4 million in lost revenue (based on current scrap pricing), about $2 million in incurred landfill costs, and lost CO2 reduction savings equivalent to the emissions of nearly 5,000 cars on the road every year.
