Sustainable Concrete Production As Feldbach Plant Harnesses Solar Power
In a significant stride toward sustainability, the Rohrdorfer ready-mixed concrete plant at the Feldbach site in Austria has been harnessing renewable energy through the installation of a state-of-the-art photovoltaic (PV) system since mid-2024. This innovative development is part of the company’s ongoing commitment to environmental responsibility, as it aims to integrate more sustainable practices into its operations.
The photovoltaic system, which covers a roof area of 150 m², has been installed by the Austrian solar specialist 10hoch4, under the guidance of expert Gernot Fohleitner. With an output of 33 kWp, the system is capable of producing 29,000 kWh annually. This energy generation helps reduce the plant’s carbon footprint while conserving natural resources. Depending on seasonal conditions, the PV system is capable of supplying up to 50% of the plant’s energy needs, with excess electricity fed into the local power grid, further supporting the region’s energy supply. This initiative is part of Rohrdorfer’s broader “Initiative 3033,” launched in mid-2023. The aim of this ambitious programme is to achieve energy self-sufficiency by covering at least 30% of the company’s electricity needs through its own renewable energy sources by 2033.
The Feldbach photovoltaic system is just one of the many steps Rohrdorfer is taking to reach this target. The company is also investing in additional technologies, such as waste heat utilization and geothermal energy, to reduce its ecological footprint and foster energy independence. Rohrdorfer has already implemented or is in the process of planning 44 solar PV projects across various sites, with a collective output of 12.4 MW peak. One of the most notable achievements so far is the completion of the largest PV system in Berglern, which is a significant milestone in the company’s path toward self-sufficiency. These ongoing projects demonstrate Rohrdorfer’s unwavering commitment to integrating modern technologies that support both industrial growth and environmental sustainability. With the introduction of the photovoltaic system at the Feldbach plant, Rohrdorfer continues to lead by example in the cement and construction industry, proving that it is possible to combine cutting-edge industrial operations with ecological responsibility.
This successful implementation underscores the company’s commitment to sustainable development, energy efficiency, and active participation in global climate protection efforts. As Rohrdorfer looks toward the future, the company is not only committed to reducing its environmental impact but is also taking meaningful steps to ensure that its energy needs are met in a sustainable and efficient manner. Through the continued expansion of renewable energy initiatives, Rohrdorfer is shaping the future of green manufacturing, setting a benchmark for other industries to follow.
