Guiding the transition: the future beyond EtO sterilization
EtO sterilization transition: Process-Driven strategies with vH₂O₂ and moist heat
Process-first sterilization for complex medical devices
The transition from ethylene oxide (EtO) sterilization is redefining how heat-sensitive medical devices are sterilized. Material compatibility, device complexity and evolving regulatory expectations are making traditional approaches no longer sufficient.
Sterilization is no longer a technology choice.
It must be governed as a process.


Our commitment: moist heat and vH₂O₂ as the safest and most efficient alternatives
At Fedegari, we support this transition through a process-driven approach based on two technologies:
- Moist Heat, when material compatibility allows
- Vaporized Hydrogen Peroxide (vH₂O₂), for heat- and moisture-sensitive devices
These are not alternatives by default, but they are selected and developed based on process requirements.

What this enables
FEDEGARI TECH CENTERS
Sterilization performance is not a property of the sterilant: it is the result of how the process is developed and controlled.
Fedegari Tech Centers
are where sterilization processes are experimentally developed, tested and validated.
Here, we evaluate material behaviour, sterilant diffusion, residual levels and process parameters.
This enables the development of tailored sterilization cycles for complex devices, including multilayer packaging and multi-material assemblies.
The following table is not a theoretical dataset, but the result of real sterilization development activities on complex medical devices.
Fedegari has successfully addressed long and non-vented geometries, multilayer packaging systems and heterogeneous material combinations, achieving sterility assurance levels up to 10⁻⁶ (12 log reduction), with controlled residuals and full product integrity.
