Stena Recycling Lab

Our focus areas are


Increase efficiency in recycling processes, to achieve better sorting and to create safer work environments.


Create more efficient processes.

Product development

Aiming at creating new products from materials that today are considered waste residue or that otherwise go to energy recovery.

Examples of projects

We cooperate with entrepreneurs, partners, researchers and students to meet challenges and find new opportunities, aiming at streamlining recycling processes and create new products from unwanted materials. Here are some examples of completed research projects.

Combitech and ABB logotype


Using advanced sensor technology from Combitech and the latest robotics from ABB we developed a robotic solution for more efficient sorting of plastic in electronics. We showed that it’s possible to sort high grade plastic from the electronics, so that it can be recirculated as new raw material. With the aid of new technology and digitalization we can create purer flows of material, thus supporting sustainability in both society and manufacturing industry. The lab in Halmstad provided both the sufficient space and large amounts of products for the tests.

Volvo cars and Repur AB logotype


Waste ends being waste as someone develops a new use for it. By constantly challenging ourselves we can create new products. The collaboration between Volvo Cars, Repur and Stena Recycling resulted in a car hood sound absorber. The material comes from old car seats, showing a new way to close the loop. At Stena Recycling Lab the project used equipment and expertise in order to manufacture the prototypes.

Repur AB logotype


Sustainable construction is crucial now. Demand for eco-friendly and climate-friendly building materials is rising. Repur Cement, a new lightweight filler, fills a need previously met by virgin raw material products. Insulation from old refrigerators makes up the product. Instead of energy recovery, the material is used to build and renovate floors. Repur AB began manufacturing and selling the product after successful tests at the Stena Recycling Lab in Halmstad. Repur and Stena Recycling have created other recycled products.

Hacking societies’ challenges!

Stena Recycling is a proud sponsor of Openhack Gothenburg. Openhack is a digital collaboration arena where ideas and knowledge are exchanged to solve humanitarian challenges.

Openhack Gothenburg acts as a platform for meetings to give life to new innovations. Technical volunteers, NGOs, influencers and sponsors gathered in this arena to collaborate. The event was free and open for everyone with no previous experience of coding required – the only requirement was ideas and the motivation to create new technical solutions for humanity.

Resources at Stena Recycling Lab

Stena Recycling Lab offers a creative and inspiring collaboration arena, with access to Stena Recycling’s own experts in recycling and materials. At our site in Halmstad, we can offer large-scale testing in real-world conditions, with access to state-of-the-art machinery and large material flows. In our material laboratory, materials and products can be tested, in order to evaluate and develop recycling potentials.

Library of materials

We have a library of materials consisting of a variety of types of recycled materials or residual products. The materials consist of everything from different types of plastics to mixtures of metals and mineral materials. The purpose of the library is to inspire and simplify the development of new materials, products and processes.

Machinery and equipment

Stena Recycling Lab provides access to the material test equipment at Stena Recycling. There are also laboratory machinery, such as a small mill for crushing materials, ovens for drying, as well as fume cupboards and storage space.

Interact with experts

Here you can also access expertise from different parts of Stena Recycling. Both experts on various materials and personnel with detailed knowledge of the processes currently used in recycling. Prior to each collaboration project, we assemble a project-tailored team.

Coworking arena

As you carry out projects in the Stena Recycling Lab, we also offer office space and fully equipped conference rooms. All in an inspiring environment, with access to coffee and tea. On site there is also access to a lunch room and dressing rooms with showers.

Joint venture financing

New Ventures is a unit within Stena Metall that can join and start new businesses together with the originator. New Ventures can invest in startups as well as in more established companies that create new opportunities for and by recycling. Stena Recycling Lab is by this also a facilitator, enabling you to faster reach the market with new solutions.
