POME as the most contaminated waste can be effectively utilized for biodiesel production. Supercritical transesterification offers more advantages over the other processes including higher reaction rate, without catalyst constraint, producing pure glycerol, and simple product separation process. The addition of co-solvents like CO2 should be investigated for supercritical biodiesel production from POME. Although POME is an inexpensive source to synthesize biodiesel, innovative processes are needed to maximize the oil recovery from POME. Optimization of transesterification parameters is required for high production yields and sustainable processing. © 2021 Wiley-VCH GmbH publisher: John Wiley and Sons Inc date: 2021 type: Article type: PeerReviewed identifier: Zulqarnain and Yusoff, M.H.M. and Ayoub, M. and Hamza Nazir, M. and Zahid, I. and Ameen, M. and Abbas, W. and Shoparwe, N.F. and Abbas, N.
