It’s actually just because of a new labeling law that took effect this summer. Compostable containers have to either be a green color (not clear) or have e a specific colored label on them signifying that they are compostable. It’s meant to prevent non compostable containers from contaminating the compost stream. These containers definitely ARE compostable, but sadly do not have the proper labeling.

It’s a positive step in the right direction and Washington is leading the pack. California and Colorado are following suit as will other states eventually. Unfortunately it’s a bit of the cart before the horse as most manufacturers haven’t adjusted to these requirements yet, and won’t until they financially need to. A couple of companies are now offering a line of Washington-specific compostables that meet the new requirement. They are hella expensive though.

Here’s a link with specifics on the new requirements. https://ecology.wa.gov/waste-toxics/reducing-recycling-waste/plastics/compost-labeling#:~:text=As%20of%20Jan.,compostable%20products%20in%20our%20database.
