Plastic Cups

Other Recycling

Check the symbol on the bottom of the cup first! 

Hard plastic cups labeled #1-6 are accepted in recycling. Make sure they are free of liquid before putting them in the bin!

If  this cup is made of “compostable” #7 PLA plastic, it should go in the landfill.  These cups frequently have a green band around them. Though designated compostable, the PLA material can’t properly break down in Richmond’s composting facility where we send our waste. Sustainable Berkeley Lab is currently working with the Cafeteria and eBuy to eliminate these cups from our site. Check out this post to learn more about the subject. 

Ways to Reduce

Purchase Reusable Cups

Red Cup Living makes a reusable cup that looks like the classic red Solo® cups. Consider purchasing these cups as an alternative to the disposable cup, in order to reduce your plastic waste.
