Abstract
Clinical laboratories perform a variety of tests for which biomedical waste is a byproduct. Of these, the complete metabolic panel (CMP) produces a significant portion of this waste. We investigated specific waste subsequent to performing CMPs over the course of a year and analyzed what percentage of the waste produced could have been recycled. Patient testing volumes were collected retrospectively from July 14, 2021, to July 14, 2022, for individual assays within the CMP performed on Abbott Alinity c instruments (n = 6). The average weights for components of the reagent kits, which includes wedges, boxes, and package inserts, were calculated. These weights, in conjunction with total patient testing volumes, were used to determine the amount of waste produced. A total of 1089.2 kg of reagent kit waste was estimated to be produced by performing CMPs throughout a year. Of this waste, most (855.5 kg) was not recyclable, but a subset (233.6 kg) was. Overall, 21.4% of the total specific waste weight was found to be recyclable. The CMP contributes a substantial amount of waste when performed on chemistry analyzer platforms in the clinical laboratory. Paper inserts and cardboard packaging, however, presented opportunities for recycling.
