Due to an upsurge in urbanization and industrialization, huge amounts of municipal solid waste (MSW) are accumulating on our planet. Waste generation has several negative environmental repercussions, making it a topic of debate in the environmental community. In the context of the circular economy, efforts have been made worldwide to establish a systematic management approach coupled with a sustainable treatment technology to maximize the resource usage of MSW. This review systematically discusses the recent technological developments for the valorization of MSW into valuable chemicals and energy. It focuses on the circular economy concept based on the material-centric approach and highlights the sustainable processing mechanisms of MSW through chemical, biological, and thermal processes, including hybrid and integrated thermo-bio-chemical biomass waste conversion technologies. The potential economic, environmental, and health impacts of valorizing MSW material into high-value fuels and chemicals were discussed. Future perspectives and challenges in managing MSW and valorization for practical large-scale applications are also addressed. This review would be interesting for scientific and industrial communities to boost MSW management and valorization through sustainable, effective, low-cost approaches.

Abstract
Due to an upsurge in urbanization and industrialization, huge amounts of municipal solid waste (MSW) are accumulating on our planet. Waste generation has several negative environmental repercussions, making it a topic of debate in the environmental community. In the context of the circular economy, efforts have been made worldwide to establish a systematic management approach coupled with a sustainable treatment technology to maximize the resource usage of MSW. This review systematically discusses the recent technological developments for the valorization of MSW into valuable chemicals and energy. It focuses on the circular economy concept based on the material-centric approach and highlights the sustainable processing mechanisms of MSW through chemical, biological, and thermal processes, including hybrid and integrated thermo-bio-chemical biomass waste conversion technologies. The potential economic, environmental, and health impacts of valorizing MSW material into high-value fuels and chemicals were discussed. Future perspectives and challenges in managing MSW and valorization for practical large-scale applications are also addressed. This review would be interesting for scientific and industrial communities to boost MSW management and valorization through sustainable, effective, low-cost approaches.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
