Our recycling company can't even just name the numbers that are recyclable. They give us a list of examples and name some items, but it's nowhere near comprehensive even for some things commonly used. For example, reusable plastic food storage containers (tupperware-like items) are not listed. To-go containers are prohibited, but these are heavier, more durable plastic.

If something seems recyclable, I'll throw it in on the chance that the sorters will accept it, rather than guaranteeing it goes to the landfill by putting it in the trash bin.
