Abstract:
While providing a diverse range of dairy products, the dairy business generates an enormous amount of waste and byproducts. Because of their higher chemical oxygen demand level (COD) and substantial nutritional contents including protein, lactose as well as fat, alternative biotechnological uses of these wastes for aerobic and anaerobic biological treatment must be discovered. This paper provides a critical evaluation of fermentation engineering elements that are focused on defining the effective use of dairy effluents in the manufacture of various microbial products including biofuel, organic acid, enzyme, biomass production, and polymer. In addition to microbial activities, techno-economic evaluations of the integration of specific microbial products into the biorefinery, as well as the viability of related processes, were given. Overall, incorporating dairy wastes into the intended microbial processes appears promising for commercial applications. In terms of biogas production, the digestion of dairy wastes with cow manure and/or various substrates will generate a positive net present value (NPV) and a payback period (PBP) of less than 10 years to the plant.
