Nanomaterial recycling offers many benefits on both environmental and economic issues. Nanomaterials can be recycled from both new/pure products (from nano manufacturing) and used products (nano waste: waste from nano integrated products). In addition, the recycled current construction waste, plastics and textiles may contain nanomaterials These nano sources in the waste stream recycling process could be liquid (suspensions containing nanoparticles) or solid (solid matrices integrated with nanoparticles). To recover these nanowastes, various methods have been used for separation of nanoparticles, such as (i)centrifugation, (ii)solvent evaporation, (iii) magnetic separation, (iv) using pH/thermal responsive materials, (v) molecular antisolvents, or (vi) nanostructured colloidal solvents. To archive the efficient recycling, the effect of recycling process on the intrinsic recyclability properties of nanomaterials (thermal/ mechanical/ chemical/ magnetic/ optical properties) are required. This book provides information on the recycling of nanomaterials. It focuses not only on the appropriate recycling strategies of nanowastes, but also on the nanowaste regulations (including the nanowaste disposal and recycling standards). In addition, the promising applications (reuses) of these recycled nanomaterials are also presented. It is an important reference source for materials scientists and engineers who are seeking to increase their undeerstandingi of nanomaterials recycling processes and techniques. Provides information on how nanoscale recycling techniques can mitigate the most hazardous effects of nanomaterialsExplains the major recycling processes and techniques used for nanoscale materialsAssesses the major challenges of implementing nanoscale recycling approaches in a scalable and cost-effective manner
