Prof. Dr. Zollfrank ist Inhaber der Professur für Biogene Polymere am TUM Campus Straubing und ein Experte für Biowerkstoffe. Er und sein Team beschäftigen sich mit den Themenbereichen archaeo- und bioinspirierte Materialsynthese, Biokunststoffe und biologisch unterstützte Materialsynthese. Ergänzend zum Interview mit Gangolf Wasmeier vom ZAW in Straubing, haben wir bei Prof. Zollfrank nachgefragt, ob eine Welt ohne Kunststoff denkbar ist, ob Mikroplastik durch biologisch abbaubare Kunststoffe verringert werden kann und was am Ende des Abbauprozesses eines Biokunststoffs übrigbleibt. „Wenn die Frage ist, ob wir so weitermachen können wie bisher: Dann ein klares Nein! Wir müssen einiges verändern“, so Zollfrank.
