Biorefinery of Industrial Effluents for a Sustainable Circular Economy provides a combined approach on environmental engineering, which involves the improvement of the natural environment or remediation of polluted sites. In addition, it discusses bioprocess engineering involving the development of processes for the manufacture of products from biological materials to produce a valuable bioproduct. It covers sources, impacts, and applications of industrial effluents that could potentially be used as feedstock for the IEB with examples of applied research that demonstrates the relationship between the effluents, biorefinery, treatment and bioproduct recovery. Materials that can be produced from IEB and the treatment processes for such are considered.
