Styrofoam

Composition

Expanded polystyrene foam filled with air (95% air, 5% polystyrene).

Environmental impact

Styrofoam can take hundreds of years to decompose in nature, causing long-term ecological problems and placing a burden on ecosystems.

Disposal instructions

Clean Styrofoam (with no stains) should be taken to a recycling yard. Styrofoam used in food packaging is typically disposed of in mixed municipal waste.

Factoid

By recycling Styrofoam, it can be repurposed multiple times—for instance, in producing various other PET packaging or in construction (for thermal plaster, lightweight concrete), reducing the use of new raw materials.
