For decades, we have maintained pollutant emissions to ⅓ of the maximum value permitted by Italian law in our brass forging production plant (Pressco). Exceeding standards for indoor environmental quality is a fundamental aspect of our manufacturing culture. In 2023, we implemented an additional Quality Management System in tandem with ISO 9001 certification to further improve system consistency. This is a core example of Caleffi’s commitment to going above and beyond in sustainability matters that impact our employees and the environment.
Annually, Caleffi utilizes more than 15,000 tons of brass alloys. To reduce the carbon footprint of our manufacturing process, brass is exclusively procured from mills in northern Italy and Germany. Over 90% of the brass we use is from recycled materials, including scrap from our own manufacturing processes.
In 2024, the North American headquarters added a solar photovoltaic array to its building expansion, which now supplies two-thirds of the facility's energy needs. Both the new expansion and original warehouse feature radiant heating to deliver optimal comfort while minimizing energy intensity.
Globally in 2025, Caleffi facilities harvested 1,572,826 kWh of energy from photovoltaic systems. A key driver was our Gattico plant, where a system with a nominal capacity of 1 MWh was brought online in 2024 and produced over 1.3 million kWh in 2025 alone.
Sustainable manufacturing is a central key to our holistic approach. Through the Caleffi Green project, we combine responsible production with expert application support to ensure our products deliver maximum energy efficiency. While we represent one part of a global movement toward sustainability, you can count on us to remain a trusted partner offering longstanding guidance in energy-efficient design and renewable integrations through our educational resources.
