With the inevitable rise in human population, resource recovery from waste stream is becoming important for a sustainable economy, conservation of the ecosystem as well as for reducing the dependence on the finite natural resources. In this regard, a bio-based circular economy considers organic wastes and residues as potential resources that can be utilized to supply chemicals, nutrients, and fuels needed by mankind. This review explored the role of aerobic and anaerobic digestion technologies for the advancement of a bio-based circular society. The developed routes within the anaerobic digestion domain, such as the production of biogas and other high-value chemicals (volatile fatty acids) were discussed. The potential to recover important nutrients, such as nitrogen through composting, was also addressed. An emphasis was made on the innovative models for improved economics and process performance, which include co-digestion of various organic solid wastes, recovery of multiple bio-products, and integrated bioprocesses.

使用好氧和厌氧消化技术从有机固体废物中进行资源回收和循环经济。

随着人口的不可避免地增加，从废物流中回收资源对于可持续的经济，生态系统的保护以及减少对有限自然资源的依赖变得越来越重要。在这方面，基于生物的循环经济将有机废物和残留物视为可用于供应人类所需的化学物质，营养物质和燃料的潜在资源。这篇评论探讨了有氧和厌氧消化技术在生物循环社会发展中的作用。讨论了厌氧消化域内已开发的路线，例如沼气和其他高价值化学品（挥发性脂肪酸）的产生。还讨论了通过堆肥回收重要营养素（如氮）的潜力。
