Rapid urbanization has increased the demand for food, feed, and chemicals that have in turn augmented the use of fossil-based resources and generation of organic waste. Owning to the characteristics like high abundance, renewability, and ease of accessibility, valorization of organic wastes serves as a potential solution for waste management issues. Several industrial wastes, due to their organic and nutrient-rich composition, have been utilized as a resource for the production of value-added products such as biofuels, biopesticides, biohydrogen, enzymes, and bioplastics via microbial fermentation processes. The process consists of pre-treatment of the waste biomass, production of value-added product in reactors and downstream processing for product's recovery. The integration of new comprehensive technologies for organic waste utilization will also stimulate the transition towards a circular economy. Therefore, the feasibility and sustainability of the production of various value-added products from biowastes and byproduct streams will be discussed in the present review.

快速的城市化增加了对食物、饲料和化学品的需求，反过来又增加了化石资源的使用和有机废物的产生。由于有机废物的丰富性、可再生性和易于获取等特点，有机废物的增值可作为废物管理问题的潜在解决方案。一些工业废物由于其有机和营养丰富的成分，已被用作生产增值产品的资源，例如通过微生物发酵过程生产生物燃料、生物农药、生物氢、酶和生物塑料。该过程包括废弃生物质的预处理、在反应器中生产增值产品和产品回收的下游加工。有机废物利用综合新技术的整合也将刺激向循环经济的转变。因此，本次审查将讨论从生物废物和副产品流生产各种增值产品的可行性和可持续性。
