Recycling Events

STYROFOAM COLLECTION (packaging blocks, sheets and coolers)

Next collection date: Saturday, September 11, 2021. Location to be determined. Drop-off hours will be from 12 noon to 3:00 p.m. In addition to Styrofoam we’ll be collecting wine corks, CDs and DVDs. (Sorry but we cannot accept egg cartons or food trays made of Styrofoam.)

Please: remove packing tape, stickers, and other glued-on material; do not break the Styrofoam into smaller chunks; and, do not bag it in black garbage bags (clear bags are OK). It is important that Styrofoam we collect is CLEAN and ready to be processed.

Our last collection event was held on February 6, 2021. It was a big success: nearly 200 households brought Styrofoam and other items for us to divert from the landfill and reuse/recycle.

In case you miss the event and have a large amount of Styrofoam, you might want to contact our drop-off partner Princeton Moulding (see below). If someone is already planning a trip to Somerville, or if neighbors would like to combine their loads, perhaps they would like to deliver their styrofoam on their own.
