That is why Reynaers Aluminium focuses on sustainability, during the production process as well as during the life cycle of our aluminium solutions. Reducing our environmental impacts starts at the material level. To obtain pure aluminium, aluminium oxide is melted during an electrolytic process - the Hall-Héroult process. By using green energy from hydropower plants, we reduce our carbon footprint to four kilograms of carbon dioxide per kilogram of aluminium. That is about half of the European average! The result is what we call low-carbon primary aluminium. Next to an energy-efficient production process, aluminium products are known for their long lifecycle and unlimited recyclability. In fact, aluminium can be repurposed an infinite amount of times without loss of quality. It makes the need for electricity during the initial production process a one-off investment. ![Interior view of The Giving Tree private project.
