Reusing or recycling waste cooking oil (WCO) is an alternative to manage the abundance of WCO and sustain the environment. The main concern about WCO is how it will end up and how to overcome the problem of WCO and reduce WCO mainly from restaurants and homes. This paper aims to review and focus on the synthesis of polyurethane (PU)-based polyol via the hydroxylation of waste frying cooking oil. This study involves treating WCO for purification purposes and using different acids in the hydroxylation reaction to produce polyol. The purification of WCO includes heating, filtration, and treatment. The use of different acids, either formic acid or acetic acid, can improve the formation of WCO-based polyols in terms of the modification of the structure. The synthesis of PU from WCO is a great method to overcome the problem of WCO and a great way to sustain both renewable and non-renewable resources by reusing and recycling WCO. © 2023 Malaysian Institute of Chemistry.
