Black Earth Soil Give Away

Watertown is offering free finished compost to residents. Black Earth’s finished compost was created using food scraps from Watertown residents. We are closing the circle, and providing soil back to residents to use in backyards and gardens. This is open to all residents, even if they are not enrolled in the food scrap collection program. Please bring your own buckets and shovel to take soil away in. Available while supplies last at the event. Come early if you are very interested in getting soil!


Watertown is partnering with Helpsy to recycle and repurpose old textiles and clothes. Clean out your closet before the spring and donate clothing and textiles. Helpsy also offers free curbside collection. To learn more visit: Textiles Recycling | Watertown, MA – Official Website (

Paper Shredding

Watertown is partnering with Shred-it, to securely shred confidential papers. All shredded paper will be recycled with Stericycle. Please only bring documents that are confidential — other paper materials should be placed in your curbside recycle bin. If materials are already pre-shredded, please place in a paper bag.

 Shred-it can accept papers with staples in them.
 Materials should be placed in paper bags or brought in boxes. The boxes will be returned.
 Materials will be shredded on site.

Styrofoam Recycling

Watertown is partnering with Save That Stuff to recycle Styrofoam. Please collect and save any Styrofoam you have for this event. Styrofoam CANNOT go into curbside recycling totes.

 They only accept rigid white Styrofoam
 If it SNAPS when you break it, it is the correct type
 NO packing peanuts or take out containers

Plastic Caps and Lids

Watertown has a recycling partnership with the organization Plastic Recycled. They locally shred plastic bottle caps and other plastic caps and lids and turn that recycled plastic into park benches and other items. The Recycle Center and DPW offices both have collection bins. Once Watertown has collected 500 pounds of plastic, we will receive a bench for the Library. We are roughly halfway to our goal. Help us reach it at this event!

 Examples of caps include
o Plastic drink bottle caps
o Milk carton caps
o The flat 6-pack plastic pack that hold cans together
o Container lids (yogurt, detergent, dishwashing liquid…etc.)
o Must be plastic—no metal/aluminum
o No plastic films
