WANDEGA, Flávia F. et al. Biorefinery to produce bioplastic and protein from whey using the ASPEN simulator. Rev. cienc. tecnol. [online]. 2020, n.33, pp.1-10. ISSN 1851-7587.

The aim of this work was to evaluate the technical and economic feasibility of installing a biorefinery, capable of being integrated into the dairy industry to use whey effluents and to produce bioplastic polyhydroxybutyrate (PHB) and protein. Based on scientific literature, the unit operations of the PHB and protein production processes were established through the Aspen Plus Simulator, 8.8 version. Escherichia coli recombinant strains were used for the metabolic biosynthesis of PHB with propylene carbonate solvent while ultrafiltration was used to extract the protein. The installation of a biorefinery, integrated to a dairy industry that processes at least 250000 L of milk per day was viable from both a technical and an economic viewpoint.
