From the organizers:

Have stuff to recycle that doesn't go in your cart? Bring it to the West Seattle Recycling & Reuse Collection event on Saturday, March 8 between 9:00 AM and 12:00 PM! We host this event every year to collect items for recycling and reuse that can't go in your home recycle carts or dumpsters. Events are free and open to all Seattle residents.

We heard your feedback and made big changes! This year, you’ll park your car in the South Seattle College north parking lot and walk your material to each truck instead of waiting in a long line of cars. Early and late drop-offs will not be accepted, and trucks leave when full.

Foam blocks
Household batteries (no damaged batteries)
Florescent tubes and bulbs (no broken bulbs, limit: 4 ft.)
Small, empty propane camping canisters
Small electronics (TVs, computers, etc.)
Small appliances (non-freon)
Paper for shredding (limit: 4 boxes of paper)
Clothing, accessories, bedding, and curtains in good condition
Home goods and toys

ITEMS NOT ACCEPTED:
Stained, ripped, or worn-out fabrics
Mismatched items (single shoes, etc.)
