Lube-Tech PUBLISHED BY LUBE: THE EUROPEAN LUBRICANTS INDUSTRY MAGAZINE


Introduction Every year, the world generates over 930 million tons of food waste, exacerbating environmental challenges and squandering valuable resources. From production to disposal, food waste significantly contributes to greenhouse gas emissions, water wastage, and lost economic potential. However, a new wave of innovations is turning this problem into an opportunity. ChainCraft’s proprietary three-step process using non-GMO, open mixed culture fermentation enables upcycling food residues into

valuable chemicals, such as medium-chain fatty acids and fertiliser products.


These fatty acids serve as essential building blocks in industries ranging from specialty chemicals to lubricants, particularly for the production of polyol ester (POE) base oils which are highly versatile lubricants, offering customisable properties by varying the types of fatty acids and polyols used in their formulation, enabling them to meet diverse performance requirements across a wide range of applications.


Note: SCFA = Short Chain Fatty Acids (acetic acid, propionic acid, ...); MCFA = Medium Chain Fatty Acids (caproic acid, ...)
