A comprehensive resource presenting different manufacturing bioprocesses of chemical substitutes, from agricultural and industrial by-products to value-added biorefinery products Chemical Substitutes from Agricultural and Industrial By-Products: Bioconversion, Bioprocessing, and Biorefining discusses the biorefinery of chemical substitutes from agricultural and industrial by-products, covering the consolidated bioconversion, bioprocessing, and downstream process of the significant chemical substitutes produced. In each chapter, the individual aspects of bioconversion, bioprocessing, and downstream process of chemical substitutes produced from selected agricultural and industrial by-products to selected chemical substitutes are discussed. The text includes helpful case studies of specific processes to aid in reader comprehension. Edited by four highly qualified academics, Chemical Substitutes from Agricultural and Industrial By-Products includes information on: Common substitutes for chemicals obtained from biomass of agricultural wastes and industrial by-products, including antioxidants, oleoresin, nanocarbon materials, enzymes, essential oils, bio-bleaching agents, and biosugars Alternative substitutes, including biofertilizers, cocoa butter substitutes, bio-succinic acids, furfural derivatives, levulinic acids, and cellulases Economic calculations, such as cost analysis, of different bioprocesses to analyze their feasibility in business and general industry Environmental impact analysis of chemical substitutes from agricultural and industrial by-products for a sustainable agriculture system Enabling readers to create a change in the perception of the waste agricultural biomass from waste to resource, Chemical Substitutes from Agricultural and Industrial By-Products is an essential resource for biotechnologists, chemists in industry, natural products chemists, process engineers, chemical engineers, and environmental chemists.
