Antonia, what sets EcoSecur apart from existing methods?

With EcoSecur, we've developed an innovative, resource-efficient, safe, and stable process specifically tailored for type 2 glass injection and infusion vials used in human and veterinary medicine. Type 2 glass, also know as ‘treated soda-lime glass’ is specifically used for containers with liquid products that are characteristically acidic or alkali-neutral.

This groundbreaking technique utilises a liquid treatment process that enables precise dosing customised to the size of each bottle. Our manufacturing process for type 2 glass surpasses existing technologies on the market in terms of quality, process stability, and reliability, ensuring exceptional performance.

Stoelzle's EcoSecur type 2 glass product line includes a wide range of sizes, from 6ml to 500ml, available in both flint and amber glass options. They are fully compliant with EU and US pharmacopeia and ensure the highest safety for patients.

The Journey to EcoSecur: Development and Benefits

Wondering how Stoelzle developed this cutting-edge process and what benefits it brings? Here's a glimpse into the journey.

Antonia: Our first step was to analyse the different manufacturing processes available for type 2 glass. We aimed to enhance the inner coating process, making it consistent and repeatable. Our objective was to create a more environmentally friendly manufacturing process for type 2 glass compared to existing options.

By utilising a liquid treatment agent and an innovative process, we achieved reliable and precise dosing tailored to the glass size. This liquid-based approach also reduces the need for chemical materials, making the process safer.

Improved ecological footprint

Through Stoelzle's EcoSecur process, we have successfully reduced the use of chemical components by up to 50% while decreasing CO2 emissions by up to 80%. This significant reduction translates into a minimised environmental footprint. Furthermore, by using liquid ammonium sulfate, we have addressed safety concerns associated with chemical usage.

How do you ensure a continuous Quality Control throughout the production journey?

Antonia: Maintaining quality control is paramount to Stoelzle's commitment to excellence. Here's how we ensure it at every step:

  • Process Automation: Introducing process automation and automated control during the industrialisation phase was crucial for success. This automation guarantees compliance with predetermined conditions at each stage of the process.
  • Automated Adjustments: Our system incorporates automatic adjustments and controls to ensure accurate treatment for every bottle. This comprehensive automation creates a controlled manufacturing environment with 100% oversight, utilising state-of-the-art inspection machines equipped with fiber optic and chamber inspection systems.
