Recycling plastics 1-6 is usually pretty straightforward, as each category correlates with a specific resin. But plastic #7 is literally the “catch-all” category. Dubbed as “Other,” plastic #7 includes those resins that do not fit into categories 1-6, including most bioplastics.
Recycling programs for the “other” category vary greatly by location. Since it is such a broad category, many curbside programs will not accept plastic #7 at all. However recycling programs are changing collection guidelines, throwing out resin codes and accepting materials based on product.
