    ABB launches new white paper describing impact of gearless mill drive technology on CO2 emissions

    ABB has released an in-depth white paper detailing the vital role that gearless grinding technologies can play in driving productivity in mining while simultaneously reducing their carbon footprint.

    One of the key findings in the report, based upon extensive testing of ABB’s current installed base of Gearless Mill Drives (GMDs), is the high level of efficiency they provide. GMDs can be up to 3.6 percent more energy efficient than Ring-Geared Mill Drives (RMDs), reducing energy consumption and operational costs of the mine.

    This level of efficiency across ABB’s GMD installed base equates to 195 kt of CO2 – the equivalent of 89,000 cars taken off the road. Even a conservative 2 percent of increased efficiency equates to 106 kt of CO2 saved, or 49,000 cars taken off the road. (more…)

  • Volvo trucks ramps up the use of low-CO2-emission steel

    Volvo trucks ramps up the use of low-CO2-emission steel

    Volvo is now ramping up the use of low-CO2-emission steel in its trucks. Volvo was the world’s first truck manufacturer to introduce this type of steel in its electric trucks in 2022. Now the company is expanding the use of low-CO2-emission steel to include all drivelines.

    The new steel is produced by the Swedish steel company SSAB and called SSAB Zero. It is made from recycled material and produced using fossil-free electricity and biogas. As a result, CO2 is reduced by around 80 percent compared to the production of conventional steel using fossil energy.

    Next year, the frame rails in around 12,000 Volvo FH and FM trucks will be made of low-CO2-emission steel. This will result in savings of 6,600 tons of CO2 Equivalents. As the availability of low-CO2-emission steel increases, it will be introduced in more truck models as well as in other parts of the truck.

    Volvo is also planning to replace other materials in its trucks with lower emissions alternatives.

    “This is an additional step towards our zero emissions vision. Steel is one of the main materials in our trucks. We are also looking to exchange other materials, such as aluminium and plastic, to low emission alternatives. We are proud to lead the way in the industry when it comes to sustainable material in our trucks,” says Jan Hjelmgren, Senior Vice President Product Management and Quality, Volvo Trucks.

    Half of the truck consists of steel

    The potential for lowering CO2 emissions is high as almost half the truck consists of steel (47 percent of a Volvo FH diesel truck), and it represents about 44 percent of the CO2 emissions from the production (cradle to gate) out of the total 21 tons CO2 Equivalents  for the Volvo FH diesel.

    Volvo Group is collaborating with several suppliers around low-CO2-emission steel. Low-CO2-emission steel will be an important complement to the traditional and recycled steel used in Volvo’s trucks.

    Volvo Trucks is committed to the Paris agreement and to achieving net-zero greenhouse gas emissions in the supply chain by 2040, at the latest.

    “We are continuously striving to further minimize our climate footprint. We are also moving towards greater circularity in both our operations and our trucks. Many of our factories, transports and dealers are today running on renewable energy,” says Jan Hjelmgren.
