Our measures are specifically geared towards selected UN Sustainable Development Goals (SDGs)which shape our strategic direction:

  • SDG 3 – Health and well-being
  • SDG 7 – Affordable and clean
  • SDG 12 – Sustainable consumption and production
  • SDG 13 – Climate protection measures

are clearly committed to our responsibility for climate protection and have set ourselves ambitious targets based on the international standards of the Science Based Targets Initiative (SBTi):

  • Reduction target 2030

Reduction of greenhouse gas emissions (CO₂ equivalents) by 40% by 2030 (base year: 2022) – in line with the 1.5° C guideline of the Paris Climate Agreement.

  • Long-term goal 2045: Climate neutrality by 2045 at the latest

Climate neutrality by 2045 at the latest through consistent avoidance and reduction of emissions and the use of suitable measures

Our Code of Conduct sets out what we stand for at Dorfner and how we want to live our values. This Code provides a framework for decision-making and action for all employees in all countries and at all hierarchical levels of our Group and our suppliers.

We have launched the digital whistleblower portal as a further building block to promote open, confidential and, if necessary, anonymous communication within the company. The portal enables whistleblowers to directly report violations of laws or regulations, as well as grievances within the company, while at the same time protecting the whistleblower.

Our raw materials - the basis for quality and innovation

We have been refining raw materials ourselves for over 130 years and focus on the highest quality. We primarily use natural materials, which we extract from our own deposits and refine into high-quality products using state-of-the-art processes. Our claim: efficient use of resources and sustainable production.

Our most important raw materials at a glance:

Sedimentary rock

about_sedimentgestein

Millions of years old mineral mixture that is thoroughly purified in complex and carefully controlled processes. This unique mixture forms the basis for many of our high-quality products and guarantees natural quality.

Kaolin

about_slider_2 (1)

The “white gold” from Europe’s most important deposit. We extract, calcine and refine it ourselves, e.g. for paints, varnishes and the paper industry. Highest quality, short distances, decades of experience.

Quartz

about_quarz

Basis for building materials, water treatment, screeds and concretes. It is also the core of our high-tech colored sands, which make surfaces durable, slip-resistant and visually appealing.

Feldspar

about_feldspat

High-purity potassium feldspar from our own deposits. Important for glass, ceramics and special applications in medicine and packaging – always with high purity and homogeneity.

Sustainability & efficiency

We continuously optimize the use of resources. Residual materials from production are upgraded to primary raw materials for other industries. In 2020, we were awarded the German Raw Material Efficiency Prize for this sustainable strategy.
