a technological and economic feasibility study

Published on 2026-04-13 by @OXFORD

Abstract: AbstractThe escalating accumulation of hospital plastic waste, primarily composed of polypropylene and polyethylene, poses a pressing environmental challenge due to the widespread use of disposable medical items and inadequate waste management practices. This study explores the thermochemical valorization of selectively decontaminated hospital plastic waste via batch pyrolysis conducted at 400°C–500°C under an inert nitrogen atmosphere. Optimal pyrolysis conditions 475°C, 20°C/min heating [...]


Our summary: This study evaluates the thermochemical valorization of hospital plastic waste through batch pyrolysis. Optimal conditions yielded 62 wt% pyrolytic oil suitable for diesel blending, alongside syngas and char by-products. A techno-economic analysis suggests decentralized pyrolysis units are feasible for sustainable waste management in hospitals.
