PMID 40084717WHAT IT FOUND
Segregating clean paper and plastic during surgery cut the operating room's weekly carbon footprint from 534.6 to 79.1 kg CO2 eq.
Staff reported the process did not slow their work pace, though they doubted colleagues' consistency.
Key findings
01The intervention reduced the weekly carbon footprint of waste disposal from 534.6 kg CO2 eq to 79.1 kg CO2 eq.
02Staff rated the segregation process as not slowing down the work pace, with a mean score of 7.33 on a 0-10 scale.
03While staff were satisfied with the project, they had low confidence that all colleagues were properly segregating waste, scoring 6.1 on a 0-10 scale.

What it does not show
The study lacked a control group, so changes cannot be definitively attributed to the intervention rather than other factors. Response rates to the staff questionnaires were inconsistent across phases, with only 25 to 64 participants responding in later stages. There were no specific baseline data on the actual amount of hazardous waste generated in the operating room before the project, so the 'before' scenario was modeled rather than measured. The study was conducted in a single hospital, limiting generalizability to other settings.

The easy way to misread this
Do not interpret the 85% carbon footprint reduction as a proven causal effect of the intervention alone. The study had no control group and compared post-intervention data to a modeled hypothetical baseline, meaning other changes in hospital waste management or surgical activity could have influenced the results.
