call for startups:

We are looking for innovative materials, technologies and business models with concrete links to the Feddersen Group. The solutions should positively influence the areas of plastics compounding, distribution or processing (incl. adjacent value-added steps) and make a measurable contribution to the sustainable transformation of the plastics industry.

co-innovate transforming

We offer you

We are also driven by the vision of a sustainable plastics industry. We will find out together what this looks like in detail: recyclates or bio-plastics? Better waste recycling, functioning closed-loop systems, reduction of the use of fossil raw materials through artificial intelligence? Whatever the case, we see it as our responsibility to create a sustainable impact together.

As part of the Feddersen Group, we have access to comprehensive expertise, international market access and equity capital. We want to share our experience and resources in long-term and strategic partnerships to make the plastics industry fit for the future and accelerate its transformation into a circular economy.

We are looking for you

Are you developing solutions for a circular and fossil-free future of the plastics industry? Your ideas have the potential to have a sustainable, transformative impact and you think the time is right to start implementing them? Then let's talk about how we can achieve our goals together.

We want to achieve
together with you

We consciously open up our innovation processes to work with start-ups and co-innovators. Only when we pool our competencies and share our resources can we make a big difference.

In order to achieve maximum impact, we focus on the areas in which our core competencies lie. Our offer to rethink the world of plastics together therefore focuses in particular on the areas of plastics compounding, distribution and processing.

feddersen group

With the internationally operating Feddersen Group, port F has a strong foundation. The group's core competencies lie in the development, production, and distribution of technical polymers, in mechanical engineering and development as well as in trading in machinery for polymer processing. Engineering services, wholesale, foreign trade in stainless steel and other raw materials and technical products are further important pillars of the group.

Today, the Feddersen Group still sees itself in the tradition of its founder as a family business, for which humanity in dealing with employees, customers and partners is important, which pursues long-term goals and attaches great importance to independence and robustness. At the same time, it is facing up to the many current and future challenges and, with port F, has founded a unit that can act completely independently of the core business.

feddersen foundation

The K.D. Feddersen Foundation was established by company founder Karl Detlef Feddersen out of a desire to give something back to society. The Foundation has been operating a retirement home in Hamburg since 1984. The work of the non-profit K.D. Feddersen Foundation is significantly supported by the dividends distributed by K.D. Feddersen Holding GmbH. In recent years, the residential complex has been expanded and comprehensively modernised in several construction phases.
