Closed Looped Materials

Reuse and life-cycle-enhancement of rubbers is among the most pressing societal needs, as they form a significant amount of the overall polymer-waste mostly form tyres. Both, chemical synthesis, novel catalysts, and enzymatic degradation of rubber are studied to generate polymers with improved life-cycle as modern, environmentally friendly materials. Novel synthetic methodologies, self-healing behavior and the use of rubber-degrading enzymes intertwines technology with fundamental research.
