Polystyrene (PS) is a valued plastic used in many everyday items. The resin identification code for this plastic is "6."
PS (solid or foamed) starts as a liquid monomer and is transformed into a stable, solid polymer. It’s then used to produce cups, containers, and cutlery through thermoforming or injection moulding.
Recycling facilities for rigid PS cups, lids, and clamshells are limited at this time. Check with your local recycler to see if PS is accepted in your community’s recycling programme (WRAP - Recycle Now).
