From patient care to environmental health: a pilot program recycling polyvinyl chloride (PVC) from irrigation bags in urology

PVC waste from urology care contributes to environmental pollution, greenhouse gas emissions, high energy use, and increased costs, impacting public health. Effective recycling strategies remain limited. This study aimed to assess the feasibility of a PVC recycling program for urology waste.

This feasibility study implemented a recycling program for PVC waste in a urology unit. Healthcare staff, including physicians, residents, nurses, and janitorial personnel, were trained in the recycling process for empty irrigation bags, which were collected daily, weighed, and tracked. Bags were then sent to a facility to process them into high-quality PVC pellets. A cost analysis reflected financial conditions in Mexico City. Additionally, an electronic survey of 10 questions gauged participants' ease of involvement, barriers, program impact, and improvement suggestions. Statistical and qualitative analyses were conducted.

Over 15 months, 2,805 irrigation bags were collected, which corresponded to 187.93 kg of waste, yielding 186.05 kg (99%) of PVC. On a further life cycle assessment, we concluded that by recycling we saved 2,418 L of water, reduced CO₂ emissions by 930 kg, and saved 3,720 kWh of energy. Projected five-year recycling estimates suggest a potential collection of 1,527.6 kg of PVC, which will amount to water savings of 19,858.8 L, a reduction of CO₂ emissions of 7,638 kg, and energy savings of 30,552 kWh. Potential financial savings could reach €25,333.66.

A PVC recycling program for irrigation bags is feasible, with economic and environmental benefits. This initiative supports waste reduction and public health efforts.
