Fagerhult explores circular process in aluminium recycling pilot project
In a pilot project, Fagerhult and Hydro Extrusion Sweden have explored circular processes for the reuse of aluminium – focusing on efficiency and preserved material properties.
With the goal of reusing high-quality, extruded aluminium from end-of-life luminaires in the future, Fagerhult, together with Hydro, has explored the possibility of circular models in a pilot project.
“Many of our luminaires have an aluminium body, and we want to ensure that they can be optimally recycled without losing the quality or properties of the material. In collaboration with Hydro Extrusion Sweden, we are now exploring how we can close the loop,” says Niclas Thulin, Head of Sustainability at Fagerhult.
Recycling in a new light
The pilot project was initiated in connection with Norwegian Property's ambition to achieve more efficient energy use at Snarøyveien 30 in Oslo. Fagerhult then saw an opportunity to reclaim a large number of Notor luminaires, and the possibilities of recycling and circular processes were explored.
“Reuse was not possible, but since there were a larger number of luminaires, we wanted to make the best use of the material,” explains Niclas Thulin. “When extruded aluminium luminaires are recycled, it is common for the material’s properties to undergo downgrading, and then be used in die casting, for example. In this project, we wanted to close the loop and ensure the qualities of the material by allowing the original producer to process the material again. The pilot project resulted in the aluminium being melted down and reshaped, Niclas Thulin continues. Throughout the pilot project, the focus has been on circular processes and sustainable innovations. The goal has been to take new steps beyond the norm and the expected – and to overcome the major challenge of recycling used extruded aluminium – while preserving material properties.
“Aluminium is a uniquely durable metal that can be recycled almost endlessly, but like all materials, it needs to be handled responsibly,” says Kristian Frisk, Account Manager at Hydro Extrusion Sweden. “Together, we were now able to recycle the equivalent of 1,300 kg of aluminium in the pilot project, but the big gain is the insights we will take to future projects.”
Long-term solutions
With a long-term perspective and an aspiration to contribute to sustainable development, Fagerhult has pushed the boundaries of what was previously possible and taken a major step towards meeting the demand for new circular solutions.
“Together with Hydro Extrusion Sweden, we have closed the chain and demonstrated that it is possible to create new circular processes where all our aluminium luminaires can be handled circularly in the future,” concludes Thulin.

Fagerhult sets new industry standard: switching to the latest LED technology
Fagerhult is setting a new standard in the lighting industry and switching to the latest LED technology in its luminaires. One outcome of this is that the operating time is being doubled from 50,000 to 100,000 hours. “We want to make it easy for our customers to make the right choice, both for their wallet and for the environment,” says Marcus Fagerlind, Technical Manager for Smart Lighting at Fagerhult. Fagerhult is now taking the next step in the evolution of lighting technology. Going forward, the luminaires will be supplied with the latest generation of LEDs featuring Flip Chip technology. For our customers, this means lighting that offers higher energy efficiency, lower energy consumption and superior light quality – while also doubling the operating time. “Flipped” technology Flip Chip is a premium-segment LED chip that is based on proven technology. The thing that sets Flip Chip apart from standard LEDs is its design. Image gallery: LED-chips Section: Flip chip headline “An LED chip is made up of several different layers of material that determine the light’s wavelength and properties. A traditional standard chip is built like a cake with multiple layers, which the light shines up through from the bottom. Electrodes are attached at the top of the ‘cake’ and connected via gold or silver wires. Since these contact surfaces are located at the top, they also block some of the light, which affects the light output and, consequently, energy efficiency. These metal wires are also subjected to ‘stress’ in the event of temperature changes, making them a potential source of failure that can affect the working life of the LED chip,” explains Marcus Fagerlind: Marcus Fagerlind, Technical Manager for Smart Lighting at Fagerhult, at the Experience Centre in Habo, where lighting solutions are explored and demonstrated. In a Flip Chip, the cake is simply turned upside down, with all the contact surfaces at the bottom of the chip. This allows the light to flow freely, and the chip operates more efficiently without interference. Placing the contact surfaces at the bottom also helps avoid potential sources of failure in the connecting wires. As a result, the Flip Chip technology delivers a product that is both more efficient and more robust. Significant energy savings Equipped with the latest generation of Flip Chip LEDs, Fagerhult’s luminaires will increase energy efficiency by 5–10 percent, depending on their previous configuration.An efficiency improvement of this magnitude naturally has a significant impact on energy consumption and operating costs, but also on the system’s climate impact.“In an uncertain world, with energy crises following hot on the heels of each other, it has become even more important to accelerate the green transition – and to ensure that energy efficiency, economic considerations and environmental concerns go hand in hand. Every kilowatt-hour counts,” says Marcus Fagerlind.The operating time is also being extended – from 50,000 hours to 100,000 hours. A doubling of the working life, in other words, which makes Fagerhult’s luminaires a safe and profitable investment for the future. All upgraded luminaires will also have a constant light output, providing secure, stable, high-quality light throughout their working life. Extended lifetime from 50,000 to 100,000 hours, with stable, high-quality light throughout. New industry standard The switch from standard LEDs to Flip Chip covers the majority of Fagerhult’s Indoor range. Luminaire models that already feature Flip Chip will be upgraded to the latest generation of Flip Chip, as will all models that were previously equipped with standard LEDs. This change can improve the energy efficiency of the luminaires and reduce electricity consumption, meaning that with a small amount of effort, it is possible to achieve a very big impact.That sounds like a major change, doesn't it? “Absolutely,” says Marcus Fagerlind: “But this approach – daring to take the lead and make the tough decisions needed to bring about change – is very much part of Fagerhult’s DNA. We have never compromised between ergonomics and energy efficiency, choosing instead to drive our innovation efforts to find new solutions. This is an obvious step we have to take, not least for the sake of the climate. We want to take our share of the responsibility. This ought to be the industry standard.” Platinan in Gothenburg features 12,800 luminaires in one of Fagerhult’s largest innovation projects - demonstrating how the latest LED chip technology supports improved light quality and energy efficiency. Does this mean that the luminaires will become more expensive?“That’s exactly the point. We don’t want our customers to have to choose between what’s good and what’s actually even better. We also don’t think they should have to choose between strong finances and climate considerations. The cost of the upgrade will not be passed on to customers in the form of more expensive luminaires, but will be financed through the logistical benefits that the change will bring. With our pricing model, our customers gain access to the latest technology – at the same price as before.”
