Incineration of one device emits 231.94 g CO₂eModelled, end-of-life only. Excludes energy-recovery credit.Draft manuscript §4.1
Cleaning and recycling of one device emits 6.725 g CO₂eModelled. Assumes renewable electricity at the cleaning facility and German grid at the recycler.Draft manuscript §4.2
Recycling cuts end-of-life emissions by about 97% (about 34-fold)Derived from the two values above.Draft manuscript, abstract
Net saving of about 225.2 g CO₂e per device231.94 g minus 6.725 g. Used in the calculator.Derived
Device mass is 167.9 g; about 84% goes to recyclingThe 27 g pressure gauge is removed and incinerated.Draft manuscript §3.4, Table 1
Plastics in the recycling stream: PC, ABS, PA, TPUMetals and silicone / mixed parts are sorted separately.Draft manuscript §2
Cleaning verified by protein-residue testMost parts passed. Gauge thread and brass pipe failed, so the gauge is removed before cleaning.Draft manuscript §3.3

The study

Sustainability in Coronary Artery Interventions: an end-of-life comparison of incineration versus cleaning and recycling of single-use inflation devices – a technical assessment study.

Authors: N. K. Vageesan (MUMD), M. Kunz, J. Boeddinghaus, G. Leibundgut (University Hospital Basel).

Status: draft manuscript, not yet peer reviewed. Last reviewed 2026-11-08. We update this page when it is published.

Limits to keep in mind

  • One hospital and one device design, built for disassembly
  • Emission factors come from published third-party data, not metered values
  • No credit for energy recovery in incineration, no credit for avoided virgin plastic
  • Cleaning assumes renewable electricity; other grids add a small amount
  • Cost and recycling income differ by country

Documents on request

Regulatory status: the device is CE marked, with certification by an EU notified body (class I, sterile). The certificate and declaration of conformity are not published here and are supplied on request.
