Scrap thermoplastics

Scrap thermoplastics is recyclable thermoplastics, any plastic polymer material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling.

Recycling

Most polystyrene products are currently not recycled due to the lack of incentive to invest in the compactors and logistical systems required. Due to the low density of polystyrene foam, it is not economical to collect. However, if the waste material goes through an initial compaction process, the material changes density from typically 30 kg/m³ to 330 kg/m³ and becomes a recyclable commodity of high value for producers of recycled plastic pellets. Expanded polystyrene (EPS) scrap can be easily added to products such as EPS insulation sheets and other EPS materials for construction applications; many manufacturers cannot obtain sufficient scrap because of collection issues. When it is not used to make more EPS, foam scrap can be turned into products such as clothes hangers, park benches, flower pots, toys, rulers, stapler bodies, seedling containers, picture frames, and architectural molding from recycled PS.

Thermoplastic polyurethane scrap can be reprocessed.^{[citation needed]}
