Innovating for a cleaner environment

The World's Only Biofilter Project for EO Sterilization

Background and Environmental Importance

Ethylene oxide (EO) is a toxic gas widely used in the sterilization of medical devices. Due to its potential risks to human health and the environment, EO emissions must be carefully controlled and treated before being released into the atmosphere.

The Biofilter Project aims to reduce the amount of EO released into the environment through an effective gas treatment process. By reducing EO emissions to below the target level of 1 ppm, the project supports improved environmental protection and more responsible EO sterilization operations.

Our environmental commitment

• Reducing EO emissions

  Helping reduce the concentration of EO released from the aeration process.

• Protecting the environment

  Responsible control of emissions from our sterilization operations.

• Applying innovative technology

  Biological treatment technology as part of our environmental management approach.

• Responsible sterilization operations

  Environmental considerations integrated into our processes and facility operations.
