Glycerine is a by-product of the production of fatty acid methyl esters (FAMEs) during the transesterification of triglycerides such as animal fats or vegetable oils [1]. Used cooking oils (UCOs) can also be used as an alternative raw material for the production of FAMEs and glycerine [2]. Triglycerides react with methanol, producing glycerine and
