    CERATIZIT wins environmental award for upGRADE products

    CERATIZIT has received the Prix de l'Environnement 2023 (Environmental Award) from the Luxembourg industry association FEDIL for the process used to manufacture the carbide grades in the upGRADE product family.

    By using secondary raw materials from an optimized recycling process, the upGRADE carbide grades not only offer a particularly low carbon footprint, but also the high performance of a premium carbide grade.

    “Mining ore containing tungsten already pays off starting at a content of 0.06 %. This means that around 200 tons of ore have to be transported to obtain one ton of metallic tungsten, which requires a lot of energy”, explains Dr Ralph Useldinger, head of Group Analytics and Fundamental R&D. This is why CERATIZIT only uses secondary raw materials from the zinc recycling process for the upGRADE grades in order to minimize the carbon footprint of the products.

    Low CO2 emissions

    The zinc used to break up the carbide structures, is reused, meaning that the process produces emissions almost exclusively as a result of the necessary electricity. However, CERATIZIT can also score points in this area: “Since the beginning of 2023 we have only been purchasing green electricity from sustainable sources”, adds executive board member Frank Thomé.

    He also considers the upGRADE varieties to play an important strategic role. “The upGRADE product family is an important component of our sustainability strategy. They prove that more sustainable carbide products are possible without having to compromise on performance”, says Thomé.

    To ensure this, CERATIZIT only feeds high-quality, meticulously sorted carbide scrap into the recycling process. Dr Ralph Useldinger explains why this is crucial: “In zinc recycling the structure of the tungsten carbide remains unchanged. This means that the quality I put in is the quality I get out.”

    Starting with two carbide grades

    The upGRADE product family currently features two carbide grades. CT-GS20Y for metalworking, which has already won the Best of Industry Award, and KLC20+ for knives, rods and saw teeth for woodworking, which was presented at LIGNA in May. They form the vanguard of a product portfolio that, according to Thomé, is set to become increasingly sustainable in the coming years.
