Saip’s Repur technology transforms powders derived from Polyurethane processing, MFD agglomerate into useful materials

More and more companies are interested in joining sustainable processes, however, generating useful products from materials such as post-consumer polyurethane is not always an easy task.

As a way to face this challenge, Saip developed Repur, a technology for the transformation of powders derived from the processing of Polyurethane, MFD chipboard and other recycled materials. Based on a chemical and mechanical process with zero polluting impact, Repur can generate a fully workable sustainable material with remarkable properties.

“The system can help manufacturers of insulating panels and plates to convert the powders derived from processing into useful products”, explained Luca Ceresa, commercial director of Saip. It should be noted that the first line of Repur was sold to a large producer of rigid insulation.

Ceresa pointed out that “there is a lot of waste in the production of rigid panels, the pieces are lowered and molded. This generates waste that Repur can turn into useful products such as molds for 3D printing, floors, platforms, kitchen countertops, or panels”.

In a brief message to the media, the company specified that the Repur powder recycling machine is designed to take powder and mix it with a prepolymer and a catalyst that are then cured at temperatures between 40 and 50 °C.

The suspension consists of approximately 70% regrind, 23% binder and 7% hardener. In addition to polyurethane waste, the system can also use other materials that are compatible with the polyurethane binder chemistry.
