What Are the Different Uses of Glycerin from Biodiesel?

Focuses on the key manufacturing technologies of biodiesel, such as raw material acquisition, preparation process, product standards, and application of by-product glycerin. There is a special chapter on the life cycle assessment (LCA) of biodiesel. The most advanced assessment tools comprehensively evaluate biodiesel from raw materials The entire process from product to product consumption fully demonstrates its environmental friendliness and reproducibility; several beautiful pictures of energy crops and biodiesel equipment are included. This book can be used as a reference for teachers and students engaged in biodiesel research in domestic bioengineering, biochemical engineering, agricultural science and engineering, and also for reference by management and technical staff of biodiesel production enterprises. Biodiesel is popular all over the world for its environmental friendliness and renewables, and is expected to become a substitute for traditional fossil energy. ^[1]
