- W4383460666 abstract "This chapter reviews waste management and valorization in the biodiesel industry. Biodiesel is commonly produced by transesterifying triglycerides with short-chain alcohol, mainly methanol. This process is accompanied by the production of different waste streams, including oil cake/meal, wastewater, crude glycerol, waste homogenous catalyst, and waste originating from the reactivation of the heterogeneous catalyst. Oil cakes/meals are solid residues left after oil extraction from seeds. The wastewater is produced from crude biodiesel purification using water washing to remove impurities. The main byproduct of the transesterification process is crude glycerol. Waste homogenous catalysts remaining in the product mixture at the end of the transesterification reaction also need neutralization. The heterogeneous catalysts can be separated from the reaction mixture but need reactivation for repeated use. This reactivation produces another type of waste. Hence, achieving a net zero biodiesel production plant is a major challenge for the sustainable production of this renewable fuel. This review aims to provide a better understanding of the different waste streams generated in biodiesel production plants while presenting the methods for waste management and valorization to mitigate the associated environmental burdens and maximize economic revenues." @default.
