We assume responsibility

Sustainability

Pharmaceutical primary glass packaging from Stoelzle is produced with sustainability and maximum safety in mind. We take our responsibility seriously. Our sustainable approach protects what matters: people and the environment.

Sustainability for us means

Protecting the environment

As a glass producer we are proud that glass is the perfect packaging material: 100% from natural materials, sustainable, infinitely recyclable without losing quality. Glass is inert – packaging made of glass protects both its content and the consumer.

We are committed to being environmentally friendly whilst producing innovative, safe and exciting products.

Leadership principles

Our employee-focused approach is driven by the leadership principles of the “5-Ts” (trust – transparency – target driven – teamwork – talent research). Ethical behaviour, both with our employees and with our business partners is our top priority.

Sustainable partner for our stakeholders

Our stakeholders and customers can trust Stoelzle as a reliable business partner demonstrating respect for nature and its employees.

Corporate management

The top management assumes responsibility for the effectiveness of the environmental management system and leads by good example.

Knowledge

Our environmental certification ISO 14001 and our energy certification ISO 50001 increase and improve the awareness of every individual. Thanks to ongoing training and further education, the topic becomes part of the daily work routine for all employees.

Emissions

Both noise pollution as well as environmental pollution are reduced or avoided to the absolute best of our ability.
