Nachhaltige Bausteine für die Kunststoff-Herstellung: Biomasse-basierte Lipide

Plant oils are currently the principle resource for the production of bio-based, high performance polymers, such as polyamides. This process is facilitated by giant strides in chemical catalysis and biotechnology, which allows conversion of vegetable oils in "drop-in" chemical building blocks. These bio-based polymer building blocks have equivalent chemical and physical properties as well as similar cost structures compared to conventional petrochemical synthesis feedstock. This allows integration of bio-based resources into industrial production processes without significant adaptations in logistics or process configuration. However, only use of synergies between chemical and biotechnological unit operations will in future provide for sustainable and eco-efficient process designs. To allow sustainable supply of bio-oils to a growing chemical industry without a significant impact on food production demands development of alternative bio-oil sourcing strategies. In this respect the development of processes for the production of microbial oils, which have equivalent chemical properties to their plant counterparts is imperative. One leading option is the biotechnological conversion of agricultural and food waste streams into microbial oils by combining enzymatic hydrolysis and fermentative production using oleaginous organisms, such as yeasts.
