Structured Material Selection: Building Sustainable Medical Devices with Plastics
How do you make a medical device more sustainable without blowing up the business case? Lucas Pianegonda breaks down the structured way to choose plastics, and why the first win is usually deleting a requirement, not changing a material.


ABOUT THE GUEST
Lucas R. Pianegonda is founder and lead plastic expert at Gradical (Switzerland), a consultancy that helps medtech companies select materials that are technically sound, compliant, and lower-footprint. Material scientist by training, he also hosts the podcast now called MedTech Sustainability by Design.
KEY TAKEAWAYS
- Over-requirement is the biggest hidden source of cost and carbon. Challenge every "must be medical grade" before you reach for a greener material.
- The plastic pyramid: moving down from high-performance plastics (PEEK) to engineering or commodity grades, where the part allows, cuts footprint and cost at once. Twenty years ago we just called it optimising.
- You don't need a 50,000 euro LCA to decide. A rough Excel or OpenLCA estimate gets you within ~20-25%. The certified LCA is for making public claims, which the EU's Empowering Consumers Directive now requires you to back with data.
