Circular polystyrene
made in-house
Our high-quality recycled polystyrene (PS) granulates provide a sustainable and cost-efficient alternative to virgin plastics. Produced entirely in-house from discarded cooling and freezing appliances, as well as ICT and small domestic appliances, these granulates offer exceptional polymer purity, full traceability, and consistent quality.
Turning waste in to products
By combining our e-waste intake with in-house recycling operations and trusted partnerships, we manage the entire process - from depollution and treatment to pellet production - ensuring a reliable feedstock and high-performance material for use in electronics, construction, automotive, and consumer goods.
Our circular materials are a clear example of Renewi’s waste-to-product strategy in action. We don’t just support the circular economy, we make it happen. From a discarded fridge to a new PS pellet: your next product could start here.
Tailor-made to your needs
Backed by decades of expertise in plastics and a commitment to customer-centric solutions, we offer more than just standard products. Renewi can deliver tailor-made compounds that meet your specific technical and sustainability requirements.

Coolstar Plus
A high-purity recycled PS granulate, colour-sorted to an off-white tone, completely additive-free for maximum purity. Widely used in industries such as electronics, automotive, construction, horticulture, promotional items, and even toys (compliant with toy safety standards). Suitable for various processing techniques including injection moulding, extrusion, and 3D filament production.

Coolstar Master
Derived from the same base as Coolstar Plus, but modified to meet specific customer requirements in terms of technical properties and appearance. Ideal for thin-wall sheet extrusion and injection-moulded applications where higher impact resistance (e.g. drop tests) is needed.

Coolstar-E Plus (SDA)
Sourced from small domestic appliances (SDA), this black regranulate is produced via high-grade multi-electrostatic sorting and contains no additives, ensuring high purity and performance. Best suited for injection moulding applications.

Coolstar-E Plus (ICT)
Originating from ICT appliance waste, this black PS granulate offers the same additive-free purity as the SDA variant but with increased impact strength due to smart source selection. Suitable for both injection moulding and extrusion processes.

Coolstar-E Master
A performance-enhanced version of Coolstar-E Plus, engineered to meet customer demands for improved technical properties and surface finish. Recommended for thin-wall sheet extrusion and impact-resistant injection-moulded products.

Coolstar PS flakes
Sustainably sourced from post-consumer e-waste, our PS flakes are sorted to high purity and ready for injection moulding or extrusion. Ideal for compounding or direct use, they offer a circular, cost-effective alternative to virgin plastics.
