Partnerships

Acting responsibly is a key principle for COMPO throughout the entire value chain. This includes verifying that established environmental and social standards are met in business relationships as part of the company’s own due diligence obligations. Our procurement strategy takes these criteria into account throughout the supply chain and is complemented by close collaboration with trading and cooperation partners. This partnership-based dialogue, together with long-term business relationships, forms an important foundation for the continuous development of shared standards and processes.

“The ongoing development of our supply chains is a key part of our long-term procurement strategy. In doing so, we take environmental and social considerations into account throughout the entire value chain.”

Michael Düsener, Head of Purchase

Business relations and supplier code of conduct

The internal value system also provides a binding framework for shaping COMPO’s business relationships. Key principles of conduct are set out in the compliance system and also apply to business relationships. COMPO bases these on principles of integrity, fairness and respect, as well as on requirements relating to, amongst other things, employment, health and safety, product quality and environmental protection.

Transparency regarding its own sustainability activities and their external assessment is also important to COMPO in its dealings with customers and suppliers. COMPO has its sustainability performance assessed by EcoVadis in the areas of the environment, labour and human rights, ethics and sustainable procurement. In the 2026 EcoVadis rating, COMPO received a Gold award.

Collaborations

Collaboration with various partners along the value chain enables COMPO to bring together diverse expertise and technical know-how to develop new products and solutions. One key focus is the use of raw materials from circular processes.

Partnership with Reterra/Remondis

Together with Reterra/Remondis, COMPO is working on the development of products that utilise selected raw materials from circular processes. The aim of the partnership is to make such raw materials suitable for product development and to further develop their application.

Cooperation with Vienna City Council

As part of a cooperation with Vienna City Council, COMPO collects green waste from the maintenance of green spaces and uses the organic material as a raw material for the manufacture of its own products. To this end, COMPO operates a soil production plant in Vienna, where RAL-certified green compost is processed on site.

Cooperation between Störk GmbH and local authorities

In Nauen, green waste from private households in Nauen and surrounding municipalities is collected, delivered to COMPO and processed there into compost and soil protection products. The existing cooperation will be continued and further developed.
