Bislang basierte die Produktion von Nylon auf erdölbasierten Ausgangsstoffen. Diese ist umweltschädlich, weil fossile Ressourcen genutzt, viel Energie benötigt und bei der Produktion klimaschädliches Lachgas ausgestoßen werden. Ein Forschungsteam des Helmholtz-Zentrums für Umweltforschung (UFZ) und der Universität Leipzig entwickelte nun im Labor ein Verfahren, mit dem aus Phenol durch eine elektrochemische Synthese und den Einsatz von Mikroorganismen Adipinsäure, einer von zwei Grundstoffen von Nylon, produziert werden kann. Zudem gelang es zu zeigen, dass Phenol durch Abfallstoffe aus der Holzindustrie ersetzt werden kann. Damit könnte biobasiertes Nylon hergestellt werden. Publiziert wurde die Forschungsarbeit im Fachjournal Green Chemistry.
