Södra has successfully implemented a groundbreaking technological innovation at its Värö sawmill facility, setting a new, ambitious benchmark for resource efficiency and environmental responsibility within the global woodworking sector. This initiative, developed in close partnership with supplier FB Kedjor, centres on dramatically enhancing the durability and performance of the conveyor chains critical to transporting chips and wood chips—an often-overlooked yet vital component in the sawmilling value chain.
The core success of this project lies in extending the operational lifespan of the chains within the chip and wood chip conveyors. Traditionally, these components required replacement approximately every 30 months due to the demanding, corrosive environment of a working sawmill, characterized by moisture and low pH. Through the deployment of the specialised FB HYDRO chain solution, Södra has achieved an operational life exceeding 90 months—a remarkable tripling of service life. This simple yet profound change creates a cascading series of benefits that directly impact both the group’s financial health and its environmental footprint.
The innovation project, which began tracking its effects in 2017, provides a compelling, quantifiable case for how smart engineering delivers a ‘dual dividend’—simultaneous gains in operational efficiency and environmental performance.
On the operational front, extending the chain life from 30 months to over seven years has drastically reduced the need for maintenance interventions and spare parts procurement. Fewer maintenance cycles translate directly into significantly reduced downtime for the conveyor systems. This increase in equipment availability is crucial for a high-volume facility like the Värö sawmill, bolstering overall production efficiency and, in turn, strengthening Södra’s competitiveness in the international timber market.
Financially, this extended longevity has already generated substantial savings. Since the project’s inception, the recorded cost savings stand at SEK 798,637 (Swedish Krona).
More significant, however, are the documented environmental advantages. By drastically reducing the consumption of raw materials, manufacturing energy, and logistics required for replacement chains, the project has achieved:
- A reduction of 28.3 tons of CO2 emissions. This saving directly contributes to the global effort to decarbonize the industrial landscape.
- Conservation of 40,884 liters of fresh water. This speaks to a more responsible stewardship of natural resources, moving beyond just timber supply to essential production inputs.
Fredrik Molén, a maintenance engineer at Södra, underscored the broader significance of the results: “This project shows how smart solutions can create double benefits: lower climate impact and stronger competitiveness. Where the effects can also be measured. It makes a difference, both for the environment and for our business.” This sentiment encapsulates the modern industrial ethos where sustainability is viewed not as a regulatory burden, but as an engine for value creation and operational excellence.
The key to this success is the bespoke technology of the FB HYDRO chain, specifically engineered by FB Kedjor to thrive in the harsh, corrosive sawmill environment. Its long-term performance—operating without failure for over seven years—serves as definitive proof that the right technological choice can generate long-term, compounding value. Patrick Schönfeldt from FB Kedjor noted, “This is a clear example of how technological development can contribute to both profitability and sustainability.”
Crucially, Södra has leveraged an internal tool, ECOSAVING, to track and quantify these savings in real-time. This level of detailed measurement is particularly vital for a modern corporation’s sustainability reporting. The ability to monitor and report savings associated with maintenance and supply chain inputs allows Södra to precisely account for reductions in its Scope 3 emissions. These emissions, which include impacts across the entire supply chain, are notoriously difficult for large enterprises to measure and manage. The transparency provided by the ECOSAVING tool ensures that the positive impact of this single component innovation contributes meaningfully to Södra’s broader commitment to societal sustainability work.
The innovation at the Värö sawmill in Halland County is more than an isolated case of technical optimisation; it serves as a tangible blueprint for the entire woodworking industry. As sawmills worldwide strive to meet rising demand for timber while adhering to increasingly strict environmental standards and resource constraints, maximising the efficiency and lifespan of critical processing infrastructure becomes non-negotiable.
This collaborative achievement between Södra, a leader in the forest-based industry, and FB Kedjor, a specialist supplier, demonstrates the power of targeted innovation. It shows that significant steps toward a more resource-efficient and sustainable society can be found not only in large-scale capital projects like new CLT facilities or electrification of logistics, but also in the meticulous optimization of everyday machinery components.
By prioritizing resilient, long-life components like the FB HYDRO chain, sawmills can drastically reduce maintenance demands, lower carbon footprints tied to manufacturing and transport of spares, and secure robust, reliable production schedules. The outcome at Värö solidifies the notion that, for the future of the woodworking sector, operational efficiency and a profound dedication to environmental sustainability are fundamentally intertwined, driving a competitive advantage that benefits both the business and the planet. This ongoing, measurable success story marks a pivotal step toward a truly circular and high-performing wood processing industry in the Nordic region and beyond.
