In short, for us at Metso, sustainability means the implementation of our vision in our everyday business: we work hard every day to be the best choice for our customers for the responsible processing of natural resources and flow control.
How important is sustainability and the circular economy to Metso’s customers and how can Metso help with this?
Without mines, quarries and petrochemical plants, our daily lives and the world around us would look different. We need minerals, metals and other natural resources to enable our standard of living. They are vital to virtually all the consumables and structures we use.
The industries processing raw materials grapple with challenges like climate change and the depletion and degrading of ore grades. They also target to reduce the amount of water used in the process, improve the energy efficiency, and cut down the amount of emissions and waste. Solving sustainability-related challenges is directly linked to the license to operate and business success. And this is where Metso’s technology comes in: our solutions help improve the sustainability of rock and minerals processing, metal and waste recycling, and process industry flow control.
By helping to solve the above-mentioned challenges with our solutions and services, we create value to our customers and stakeholders, including society. A circular economy way of thinking is also important – the recycling of materials, closing the loops, and extending the life-cycle of equipment are some examples of the areas where our knowledge excels. Our energy-efficient mining comminution solutions, like the HRCTM high-pressure grinding technology, LokotrackTM UrbanTM mobile crushers and advanced flow control technology, as well as our metal and waste recycling solutions, are great examples of forward-looking technology that helps overcome sustainability challenges.
How do climate change and the circular economy affect Metso’s innovations?
Climate change and resource scarcity pose challenges to our customers. Helping our customers foresee and tackle these challenges even before they arise is an important element in our innovation process.
As an example, Metso’s Vertimill® grinding mills are globally recognized as some of the most energy-efficient grinding machines. They have been proven to grind more efficiently than horizontal ball mills. Typically, the energy savings ranges from 25% to 35% – and in some cases even 50%. In 2018, approximately 1,482,000 MWh of energy was saved and 652,000 metric tons of carbon dioxide reduced thanks to the use of the Vertimill®.
Environmental loads can also be reduced with several other Metso solutions. Digitalization is also one way to help our customers to further improve their processes and reduce energy consumption, for example.
When it comes to the circular economy, aspects of it have been embedded in Metso’s offering for a long time in the form of market-leading waste and metal recycling equipment, as well as asphalt, construction and demolition waste crushing technology.
Metso equipment is designed to last long. With our expert services and wear parts, we can extend the life-cycle of the equipment; and with process improvements, we can make existing customer processes more efficient.
Today, we have one of the industry’s most advanced ranges of solutions for the recycling of metals, as well as for processing solid waste and by-products. For example, our shredders and auxiliary equipment are used in scrap yards, electronic waste recycling plants and facilities that pre-process waste for the production of alternative fuels.
According to the United Nations, the number of people living in cities could double to 6.5 billion by 2050. To accommodate growing populations, more houses, parks, roads, subways, and other infrastructure, are needed – and they all need suitable construction materials, be it from natural or recycled sources.
At Metso, we have developed an industry-leading manufactured sand production process to help complement and substitute the use of the diminishing and regulated natural sand resources used for construction purposes. Thanks to the excellent quality and shape of the manufactured sand grains, the amount of cement in the concrete mix can be reduced by as much as 15 percent.
Building something new usually means that something old needs to be demolished. It used to be that asphalt and construction waste were simply transported to the nearest landfill for disposal. Today, we have solutions like mobile Lokotrack® plants that can crush and separate bitumen and aggregates for reuse as new asphalt or as fill material for different types of construction projects. At the same time, this innovative technology improves energy efficiency and reduces emissions.
