Let's get circular

In a world shared by 8 billion people, sustainability is not optional – it is essential. Each one of us has a responsibility to our planet and the future generations who will inhabit it.

We need to use resources efficiently, improve social and working conditions, protect natural ecosystems, raise aspirations and extend opportunities for all.

We need to continuously improve our business performance and by that the natural world as we live, create and build. The race toward zero carbon is driven by countries and companies around the world as ESG* investors increasingly require lower carbon footprint throughout the supply chain.

* Environmental, social, and governance (ESG) criteria are a group of standards used by socially conscious investors to screen investments.

Sustainability in everything we do

Sandwich core composite materials benefit the environment in many ways. Due to their low-density properties the cores themselves require only a small amount of raw material. When applied, sandwich solutions enable lightweight, flexible and aerodynamic designs that reduce the fuel consumption of vehicles and vessels and open for creative design opportunities.
Looking at the overall life cycle, our products also compensate for their carbon footprint in many applications thanks to the extremely long life for which they were designed.

Sustainability at Diab

At Diab we understand that our products and solutions are a natural part of the future society. We provide a wide range of sandwich core materials to fit different applications. The right core decreases cost and carbon footprint throughout the application’s life cycle. As a concrete example, sandwich composites are a driver of the competitiveness of wind energy. The lightweight materials that we provide enable efficient rotor blade design that lowers the production cost of electricity generated, which makes renewable energy from wind more competitive.

Working for a more sustainable future

Diab continues growing, and the larger and more global our company becomes, the greater our responsibility. We believe we need to make a difference on the big issues that matter to us all. That is why we have made Sustainability one of our top business priorities. A lot remains to be done, but we are determined to continue improving our performance, putting sustainability principles and ideas into practice.

We aim to be the market leader in PET foam core, which includes having the lowest carbon footprint, and to be the best partner for customers that are committed to reducing their carbon footprint and improve circularity.

As a part of our endeavor, we are following global initiatives:
