An efficient and sustainable supply chain is essential for Gränges’ long-term success and development. To ensure responsible sourcing, Gränges follows strict routines and guidelines for sourcing metals and purchasing other materials and services. Gränges’ ambition is to be a responsible and reliable business partner and for the company’s suppliers to maintain the same high sustainability standards as Gränges.
The ore required to produce aluminium, bauxite, is extracted from bauxite mines. After mining, bauxite is refined into aluminium oxide, which is the input material for the production of metallic aluminium. The mining and production of primary aluminium is energy intensive, so Gränges strives to use a higher proportion of recycled aluminium. Gränges purchases both primary aluminium and scrap aluminium. In 2017, recycled input materials constituted 15.4 (14.8) per cent of used materials at Gränges. The company works actively to increase traceability and responsible resource use for primary and recycled aluminium.
Gränges is committed to efficient processes, leading R&I and providing an attractive workplace. These areas are critical for Gränges to achieve sustainable growth.
Gränges continuously works to reduce energy consumption and thereby costs, as well as negative impacts on the environment.
By enhancing health and safety as well as diversity and equality, Gränges aims to offer an attractive workplace that encourages employees to develop professionally and contribute to the company’s success.
Gränges’ production comprises melting and casting as well as rolling and slitting. The melting and casting of aluminium are energy intensive processes and Gränges strives to reduce the company’s energy consumption. Energy costs are the most significant expense after metal and personnel costs. As a result of process efficiencies, Gränges has successfully reduced the company’s energy consumption per tonne of aluminium in the past four years. This has been done by increasing the metal yield in the production process and re-melting unavoidable production scrap. By re-melting scrap in-house rather than selling it to third parties, Gränges avoids quality degradation and energy losses involved in transporting and handling scrap.
Working closely with its customers, Gränges constantly looks for opportunities to apply its technical expertise. The company’s products increase the efficiency of customers’ production processes, as well as the performance of end products. In this way Gränges contributes to more sustainable products for customers and improves its customers’ competitiveness.
Gränges’ rolled aluminium products can be found in engine cooling products, climate control solutions, power transmissions, and packaging. Aluminium from Gränges is found in the heat exchangers of half of the world’s cars manufactured today, and the trend is towards more, smaller, and lighter heat exchangers. Increased environmental requirements for stationary heat exchangers support the shift from copper to aluminium, and Gränges has a strong position to capture these opportunities.
