Quantum dots (QDs) are tiny semiconductor particles with their unique optical and electronic properties; they are being gradually utilized in electronics, photovoltaics, biomedical imaging, and display technologies. However, their massive use prompts environmental apprehensions owing to the existence of hazardous heavy metals and their possible accumulation in waste streams. This chapter studies current developments in quantum dot recycling and its incorporation into sustainable waste management systems. This chapter evaluates modern techniques for extracting valuable elements from discarded items containing quantum dots, encompassing chemical precipitation, solvent extraction, and environmentally friendly synthesis procedures. Specific attention is given to circular approaches that permit quantum dots to be reused in secondary applications such as catalysis and environmental sensing. Additionally, in this chapter, we also examine the development of hybrid systems that combine waste recovery with material valorization through nanotechnology. Challenges such as quantum dot degradation, material heterogeneity, and safety handling protocols are thoroughly explored. The influence of legislation, regulation, and extended producer responsibility in the management of QD waste is also discussed. This chapter is a significant resource for researchers, industrial people, and environmentalists who are seeking to slow down the ecological impact of quantum dot technologies via sophisticated recycling and reuse methods.
