Re-integration of highly weathered used plastics into the circular economy

The use and dismantling of sports facilities with plastic surfaces leads to environmental problems, particularly through the release of microplastics and the loss of fossil resources. Recycling in the end-of-life phase is often neglected, which increases the environmental impact. There is a need for a deeper understanding of the effects of mechanical, weather-related and temporal stresses on recycling behaviour.

The aim of the project is to optimise the end-of-life phase of sports facilities with plastic surfacing systems and to mobilise the recycling and plastics industry for sustainable concepts in sports facility construction. Another focus is on increasing the degree of utilisation of bioplastics. The development of a recycling cascade, which enables plastics to be returned to their original application or alternative uses, is a further focus of work. This requires a modification of the plastics and the transparent provision of property data.

In addition, a sensor- and robot-assisted deconstruction system is being developed to avoid microplastics. Ecological and economic assessments support the development of recommendations for action and business models for a circular economy in order to conserve resources in the long term.
