Fuente: Agri-Waste and Microbes for Production of Sustainable Nanomaterials In this chapter, the prospect of bioinspired nanotechnology to support the efficient and sustainable resource recovery as a part of the circular economy is discussed. Similar to natural biological processes, bio-nano developments satisfy both eco-friendly and scale-changeable solutions in comparison to conventional waste management mechanisms. The chapter discusses the use of bio-nano hybrids, nanozymes, and biomimetic nanomaterials as selective captures, transformations, and reuse of valuable resources in mixed waste and other waste streams. The discussion of the way bioinspired systems have the potential to reorganize enzymatic functions, structural properties, and adaptive behavior of nature to enable resource loop closures and reduce environmental impact is conducted through the multidisciplinary lens. The technology is highlighted in the area of water purification, nutrient processing, heavy metallic sequestration, and biodegradation of solid wastes. Moreover, the aspect of implementing these technologies into a circle of use is considered, and their role in decarbonization, decentralized systems, and compliance with Sustainable Development Goals (SDGs) is demonstrated. This chapter strives to prepare a further reading on the fact that mimicking the nature in the nanoscale is the factor to redefine the waste into the assets of the future that is environmental friendly.
