Abstract Hospital plastic waste poses significant challenges due to its volume, hazardous nature, and environmental persistence. This review consolidates recent advancements in the pyrolysis of hospital waste, evaluating feasibility as a sustainable solution within healthcare management systems. Findings reveal that offers high oil yields when optimized for key operational parameters – specifically temperatures between 400 500 °C, moderate heating rates, residence times tailored specific types. The identifies polypropylene polyethylene most suitable hospital-derived plastics pyrolysis, though presence contaminants, such PVC or biological residues, can significantly hinder process efficiency compliance. Emerging studies demonstrate upgrading quality utilizing byproducts like char syngas improve overall economic ecological performance process. Furthermore, integration into systems is technically feasible scalable, especially supported by pre-sorting protocols decentralized processing units. concludes appropriately managed regulated, contribute circular economy converting energy resources while minimizing impact. These findings support implementation green economically viable technology, encouraging policy frameworks infrastructure investment promote adoption facilities.
