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 the roof of a building expansion, projected to supply over 80% of the facility's energy mix. A live feed of our panel output can be found here. The expansion and the original warehouse are radiantly heated to best deliver comfort and reduce energy intensity.
Globally in 2024, Caleffi facilities harvested 914,473 kWh of energy from photovoltaic systems. Notably at the Gattico plant, a system with a nominal capacity of 1 MWh was brought online.
Innovation in sustainable manufacturing is one key to our holistic approach. Additionally, the Caleffi Green incorporates the proper application support of innovative products to maximize the energy efficiency potential. We are a small part of the enormous undertaking required to live in a more sustainable world. Count on us to continue providing longstanding guidance in energy efficient design and renewable energy integrations from our rich educational resources culminated from our commitment to Excellence in Education.
