Plastic #7 (Miscellaneous) Landfill If made of “compostable” #7 PLA plastic, it should go in the landfill. Though designated compostable, the PLA material can’t properly break down in Richmond’s composting facility where we send our waste. Bottles, Tubs and Jars OK You can put plastic #7 bottles, tubs and jars in your recycling. Other plastic #7 items should be put in the trash. Biodegradable Plastic Is Not Recyclable Biodegradable and vegetable-based plastics are often labeled #7, but are not recyclable and should be put in the trash. Look for "BPA Free" One plastic #7 called polycarbonate, a hard plastic that appears to be almost as sturdy as glass, is known to contain Bisphenol A (BPA). BPA is a chemical that mimics estrogen and causes many health and developmental problems. When buying plastic #7, check for a “BPA Free” label to ensure your health and safety.
