Waste and Biodiesel: Feedstocks and Precursors for Catalysts is a comprehensive reference on waste material utilization at various stages of the biodiesel production process. The book discusses the technologies for converting cooking oil and waste animal fats to biodiesel, along with the efficacy of municipal waste derived lipids in biodiesel production. The use of wastewater-grown microalgae feedstock, oleaginous fungi, bacteria and yeast produced using waste substrate are also discussed. The use of various catalysts is addressed, including CaO derived from waste shell materials, fish and animal waste, inorganic waste materials like red mud and cement waste, and whole cell enzymes using waste substrate. Each chapter addresses the challenges of high production costs at a pilot and industrial scale, offering methods of cost reduction and waste remediation. This book is a valuable resource for researchers and industry professionals in environmental science, energy and renewable energy.
