Styrofoam / Block Foam
The Waste Diversion Center will not be accepting Styrofoam/block foam starting January 9, 2020, due to a machine issue with our processor, Ecocycle. We anticipate resuming our collection, hopefully within a month.
In the meantime, please check the Waste Wizard for other recycling facilities in Longmont or Boulder County for their availability in recycling Styrofoam.
