Sustainable business

When complex products, such as cars, are recycled, a difficult-to-sort mix of textiles, rubber, plastic and metal is left over. The good news is that Stena Recycling can now process this into high-quality fuel through a new process developed in Halmstad.

Samples are currently being sent to HeidelbergCement, to help reduce the use of virgin fuels in their manufacturing process. The fuel can also be used for heating or to produce electricity.

Each year, the Stena Metall Group recycles hundreds of thousands of cars and other complex products. In Halmstad, we are building the Stena Nordic Recycling Center, which will become one of Europe's most modern recycling facilities. The inauguration ceremony is on October 26, with representatives from local government and business, politicians, governors and other stakeholders invited. It is one of the largest single industrial investments in the history of the Stena Metall Group. In Halmstad, we are concentrating new recycling technologies at one location in order to recycle more materials from end-of-life products.

A problem material becomes a resource for society

One of our new processes deals with the material left over when cars and other complex products are ground down and sorted. What remains is a mix of rubber, plastics and metals from, for example, car interiors.
– Over the years, it has been a challenge to find a market for this mixture. Using new technology at the Halmstad facility, this problem material can become fuel which may be useful for heating, generating electricity or in industries with large energy needs, says Claes Lundberg, Head of Business Area Products at Stena Recycling. Through an advanced separation process, more metals can be recycled and the residual material becomes ProFuel pellets. Every day, we handle around 15 truckloads filled with material.

A resource that replaces virgin fuels

In collaboration with HeidelbergCement, a ProFuel trial is being conducted at their production facility in Slite, on the island of Gotland. Cement production consumes a lot of energy. In recent years the company has invested in changing from coal to using waste and bio-fuels in order to reduce their environmental impact. Their Gotland facility alone consumes 250,000 tonnes of sorted, processed and quality-assured waste fuel each year.
– On average, this currently constitutes a little over 70% of our fuel consumption, though we sometimes reach a replacement ratio of over 90%, which is a very good result. We have taken giant steps, but more can be done. The fuel from Stena, in Halmstad, can help us to reduce dependence on virgin fuels even further. In the first stage of the project, using ProFuel from Stena, we're talking about a sorted, processed and quality-controlled flow that will replace the equivalent of 400 truckloads of coal, says Anders Jansson, Marketing Director at HeidelbergCement Miljö.

Complying with the Paris Agreement

Anders Jansson describes Stena's long-term ambitions to make "a high-quality fuel from a waste product" as an accomplishment.
– Of course, the climate agreement in Paris affects us too. Our vision is that our concrete products will be climate neutral, throughout their life cycle, by 2030. Waste-derived fuels are key to this and the material from Halmstad can help us further our development, says Anders Jansson at HeidelbergCement Miljlö.
