Abstract: Abstract The scope of this theoretical study is to investigate the concept of biorefinery applied to the use of brewery wastewater as feedstock for bioconversions for lactic acid production using lactic acid bacteria (LAB), while examining the theoretical design, development, and costing of brewery wastewater treatment plant within the scope of wastewater recovery and reuse as formulated waste-derived nutrient media-assimilated effluents. Beer is the fifth of the most consumed alcoholic beverage in the world, nowadays, with well-established large production sites across the world, while its wastewater generation for breweries for example in China, reaching 300 million m3/year. The system design is based on sedimentation and membrane technology, within the scope of removal of pollutants that would be resulting in the generation of relatively abundant inexpensive liquid feedstock able to be recycled to produce high-value chemicals such as lactic acid while reducing the carbon footprint of the fermentation and reducing waste disposal.
