A note to eco-conscious surgical teams: It’s time to look past the marketing hype surrounding "biodegradable" positioning pads and examine the facts.
To effectively evaluate healthcare’s environmental footprint or sustainability initiatives, one must first master the complexities of the regulated medical waste (RMW) disposal lifecycle.
Don't let marketed ASTM D5511 standards mislead you. While vendors use them to claim biodegradability, these tests only apply to the simulated lab conditions of a tiny fraction of U.S. landfills, commonly known as “Bioreactive”.
The overwhelming majority, 97% to 99% of landfills, are 'dry tombs' designed to prevent decomposition and lock away solids (carbon locking). Without this context, 'biodegradable' is just a marketing term, not a functional reality. You’re paying more to feel better with very little to no environmental benefit. In fact, you could be making your hospital’s Scope 3 emissions worse!
A counterintuitive but scientifically important point: in a dry tomb landfill, a product marketed as biodegradable may actually produce worse greenhouse gas outcomes than a stable, non-degrading alternative. Here is why.
Anaerobic decomposition is the only pathway available in oxygen-limited landfills and it produces methane (CH₄) as a primary byproduct. Methane is a potent greenhouse gas with a global warming potential 25 to 80 times greater than CO₂ over 20 to 100-year time horizons.
If a product partially degrades in a dry tomb landfill:
• It converts some of its carbon into methane during that partial decomposition.
• If the landfill lacks an effective methane capture and energy recovery system, as is common in many facilities, and that methane escapes into the atmosphere as a fugitive emission.
• Even well-designed gas capture systems collect only approximately 75% of landfill gas emissions under ideal conditions, with collection efficiency declining over time.
Here’s a comprehensive document that explains exactly what happens to your surgical waste when it leaves your OR. We explain treatment, and the vast differences in Municipal Landfill designs under the EPA.
Cheers.
