This session emphasizes the introduction of new starting materials and products that are oils or oil-related materials. Oleochemicals are important materials for modern society; their properties and production processes are closely related to the progress of biocatalysis, which is a key tool for realizing the UN's Sustainable Development Goals. Papers presenting novel bioprocesses for producing oleochemicals by biocatalysis, e.g., using free or immobilized cells or enzymes for fermentation and/or microbial conversion in aqueous or non-aqueous systems, are welcome. These methodologies create environmentally friendly products and processes for the future of the oleochemical industry.
