Award for Innovative Use of Waste Rubber from Car Tires

Polish company ML Polyolefins was recognized – together with its partners – with an award for regranulate with a rubber filling.

During the International Fair for Plastics and Rubber Processing PLASTPOL, which took place in May, the winners were presented. The award in the category “Plastics Processing Technologies” went to ML Polyolefins together with the following partners: Bydgoszcz Industrial Cluster Tool Valley, Bydgoszcz University of Science and Technology and Technische Universitat Chemnitz. They developed a technology for the secondary use of polypropylene film waste granulate and rubber from car tires in large-scale products like grass grids. As reported, the project involved using homogeneous tire rubber powder with a grain size of fewer than 0.5 millimeters as a filler for polypropylene regranulate. The prepared rPP-GTR composition was the input for the injection molding process. “The difficulty was that the compound contained a minimum of 50 percent rubber filler. Thorough research into the technical parameters of the material allowed the injection mold to be made and adapted,” Professor Dariusz Sykutera, Bydgoszcz University of Science and Technology, was quoted.

The entity linking the participants and leading the work was the Bydgoszcz Industrial Cluster Tool Valley. The project was supervised by the Bydgoszcz University of Science and Technology, which also invited specialists from the Professorship of Lightweight Structures/Polymer Technology in Chemnitz. The implementation of the technology and the use of the developed compound in the final product were the part of the business partner ML Polyolefins.
