Polystyrene foam

  • Foam meat trays (and absorbent pads)
  • Shipping materials such as foam blocks and peanuts

Special instructions

Put foam into a garbage bag to keep it from blowing away during collection.

They also contain plastic which doesn't break down during the composting process and will contaminate the finished compost.​
