Soybean‐based concept biorefinery

Abstract

Soybean is an important commodity. Its processing generates a great variety of important commercial products and processable residues. Using the concept of biorefinery, it is possible to integrate different technologies and increase the value added by the whole process. In this work, we conducted an oriented review. First, a base process was chosen, which would produce edible soybean oil, soy protein, and soy protein isolate. From this base process, we listed the residues and made a review of the processing technologies to convert them into valuable products. We elaborated a process network for each residue, linking the intermediary products to their processing technologies and, subsequently, the commercial value‐added products. Based on a price and market evaluation, the result was an integrated conceptual biorefinery process for soybean processing, mostly considering the Brazilian scenario. © 2021 Society of Chemical Industry and John Wiley & Sons, Ltd

Rigid Polyurethane Foams Modified with Soybean-Husk-Derived Ash as Potential Insulating Materials

“…In the manufacturing of animal feed, soy is one of the major sources of vegetable protein, and its role in human nutrition is systematically growing as well [36]. Soy crops are grown globally.…”

“…Soybean husk, a byproduct of the soy processing chain, offers various potential applications. It can be utilized as a source for enzymes, pectin, oligopeptides, ethanol, butanediol, and polymalic acid [36]. In addition to these uses, biomass ashes derived from soybean husks have been proposed as an alternative to cement in cement-based composites [37].…”
