Worldwide there are no or few plastics that can be used for technical applications and which are also biodegradable. Besides very specific plastics with, for example, a medical application, there are no so-called engineering plastics with high mechanical properties combined with biodegradation under normal conditions. In many sectors such as construction, agriculture, horticulture, fisheries and greenery, the use of non-degradable engineering plastics, such as PET and nylon, which, after use and due to wear, have a high risk of getting into the environment, whether or not in tiny particles (called microplastics). Senbis Polymer Innovations, which in this application is accompanied by Asqa Subsidies, starts a valorisation project to develop new biodegradable polyesteramide granulates with high mechanical properties and a low cost price with its knowledge and expertise in polymer chemistry. For example, a sustainable and affordable alternative will be offered to a large number of sectors that are still dependent on unsustainable traditional engineering plastics. If this project is successful and the results are scaled up, this will provide an important solution to the global microplastic problem.
