Waste not want not: piloting a clinical waste audit at a United States university veterinary teaching hospital.

Abstract

Biomedical waste is a well-recognized environmental problem, yet less is known about the waste generated in the delivery of veterinary care compared to human medicine. The objective of this project was to develop and pilot a waste audit protocol for veterinary medicine that could inform waste management at a US university veterinary teaching hospital and the broader veterinary community. We conducted a multi-day review of the Colorado State University Veterinary Teaching Hospital's small animal surgery and anesthesia units to measure the types and amounts of waste generated during routine surgeries. Metrics included total weight, number of bags, and individual counts for specific items of concern and items with sustainable alternatives. We calculated frequencies and percentages of waste by waste audit material category and noted any erroneous materials sorted. Despite waste being a prioritized sustainability issue in veterinary medicine, this work highlighted opportunities for better education on managing and optimizing existing resources through behavior modification. This article explores ways the 5Rs (Rethink, Reduce, Reuse, Recycle, Research) could be better operationalized in veterinary hospitals.
