Mixed containers recycling

The city of Seattle prohibits recyclable plastic cups, glass and plastic bottles and jars, and aluminum and tin cans in the garbage.

What is acceptable

All items must be empty, clean and dry:

  • Plastic bottles, jars, and jugs
  • Plastic dairy tubs (yogurt, sour cream, etc.)
  • Plastic plant pots
  • Glass bottles and jars, although reusable glass items purchased with University funds should go to UW Surplus
  • Steel/tin cans
  • Aluminum cans (do not crush)
  • Aluminum Foil & Trays (do not crumple)
  • Milk, soy milk, and juice cartons
  • Aseptic food packages (AKA Tetra Pak)
  • Plastic cups
  • Non-compostable paper cups

What about the number in the chasing arrows?

The number in the chasing arrows on many plastic food containers identifies the plastic resin content, but doesn’t indicate if/how an item should be recycled. We recommend to ignore those numbers and use the guide above.
