Coolrec, a subsidiary of Renewi and Refil have launched HIPS (High Impact Polystyrene plastic), a high quality and unique 3d printing filament made from plastic recovered from discarded refrigerators, available now in the UK
From discarded fridges to high quality 3d printing filament, HIPS has a neutral off white colour which is easy to paint or glue, making it a perfect material for the 3d printing of scale models.
The new filament can also be used as a support material, and if needed, can be removed when the print is finished by a naturasolvent, limonene. The filament comes in the two standard diameters of 2.85mm and 1.75mm and has successfully been tested on many 3d printers.
Sustainable 3d printing filament
After their first recycled PET, ABS and PLA filaments, Dutch company Refil is now adding Hips to their product range. The products now offer a sustainable alternative for the growing market of 3d printing and this new material has a specific focus on architects, schools and product designers. The material prints flawless and comes with a sustainable story, creating 3d products from old fridges.
The collaboration between Refil and Coolrec is a good example of two companies on the forefront of plastic recycling working together in their own field of expertise.
“Whereas Coolrec is all about the recycling of electrical and electronic equipment, Refil transforms the acquired plastics into 3d printing filament and makes it available around the world”, says Casper van der Meer, CEO at Refil.
“Making recycled filament may seem easy, but getting a steady supply chain and maintaining a high quality over different batches is a real challenge. This is why it took us several years of development to be able to guarantee the quality of HIPS. Together with Coolrec we’ve managed to realise this”
Coolrec is responsible for recycling of WEEE (Waste or Electrical and Electronic Equipment) which recycles electrical appliances and electronic products into high quality secondary materials such as plastics, metals and other raw materials.
Arjen Wittekoek, Director of Coolrec said: “Discarded appliances are made from and still contain many valuable materials. Using innovative techniques, Coolrec is able to recover the plastics from the discarded fridges, offering the sustainable solution reusing these again in the manufacturing process of new products, such as the 3d filament.
“For us developing HIPS and the collaboration with Refil is another way to protect the world against pollution, preserve finite resources and enable our partners to achieve their sustainability targets. For this reason we are very proud to be involved in this circular collaboration.”
The recipe of the recycled plastic has been optimized for 3d printing, reducing shrinkage and warping during printing. The filament will be delivered on a unique fully recyclable cardboard spool leaving no waste behind. The spools are made in collaboration with a social workplace in Rotterdam, integrating social sustainability as well.
Refil and Coolrec are also working on a black filament of the same kind of plastic but in this case made from old televisions. It’s expected to be available in the beginning of 2019.
