Waste-Derived Nanoparticles: Synthesis, Applications and Sustainability highlights established research and technology on waste-derived nanoparticles, their rapidly emerging aspects, and future research directions. This book also discusses the involvement of waste-derived nanoparticles in sustainability, pollution, waste, wastewater, environmental impacts and challenges, circular economy, and lifecycle assessment. A general review of the processes involved in producing nanoparticles from plastic, electronic, and industrial waste is also provided, along with an explanation on important facets of waste identification as a practical input for the treatment and recovery of metal- and carbon-based nanoparticles. Potential conclusions drawn from the many regulatory mechanisms involved in the synthesis of nanoparticles are also highlighted. In addition, examples of waste-derived nanoparticles that were used in a proof-of-concept experiment are used to show how certain technologies could be used to improve the safety and quality of drinking water. Finally, current issues are explored from toxicological and lifecycle perspectives.
