Abstract

This chapter reviews current biodiesel production from various oil feedstocks and describes an innovative scum-to-biodiesel process and system development, including the specific unit operations involved in the extraction of oils from the scum. The scum is referred to as a material floating on the surface of primary and secondary settling tanks in wastewater treatment plants. The scum oils are then extracted and refined and can be converted to biodiesel. Scale-up considerations and the mass and energy balance of the process and the economic and environmental impacts of the technology are discussed. The unique technology has great potential in the recovery of wastewater scum and waste oil utilization for biodiesel production.
