MIRECO acquires Italian refractory recycling specialist Refrattari Trezzi and expands production footprint to Italy Acquisition of Refrattari Trezzi is another major step towards the decarbonization targets of RHI Magnesita, the world leader in refractories, and its Joint Venture MIRECO, Europe’s leading refractory recycling platform.

MIRECO, the Joint Venture of RHI Magnesita and Horn & Co. Group, is committed to advance the circular economy in European refractories by offering recycled (“secondary”) raw material solutions for Steel and Industrial customers. With the acquisition of Refrattari Trezzi on June 25, 2024, a strategic production facility is added to the plant network of MIRECO. The strengthened presence in Italy will enable an increased supply of high value secondary raw materials and customized services to extend our full-line services portfolio for the customers.    

“The union of MIRECO and Refrattari Trezzi is a further commitment to our sustainability strategy”, says Constantin Beelitz, Regional President RHI Magnesita Europe, CIS & Türkiye. “By increasing the use of secondary raw material such as stones or mixes throughout the refractory industry, we can significantly reduce CO2 emissions not only within our industry, but also for our customers.”

“Today marks another milestone in the longstanding relationship between Refrattari Trezzi and MIRECO. By joining forces and leveraging our combined Know-How, we will enhance our ability to offer sustainable value to our customers”, says Pietro Trezzi, Managing Director of Refrattari Trezzi.

Based in the heart of Italy’s industrial region in proximity to Milan, the company is a well-established and trusted partner to the Italian steel industry, opening up many possibilities for the combined business to provide further value to the Italian market. The current management, Pietro and Giacomo Trezzi, will both join MIRECO to continue managing and integrating the plant.

“With Refrattari Trezzi, we have been able to acquire a specialist with many years of experience in its segment and a long-standing company tradition. We clearly see a growing interest and demand from our customers for sustainable products and solutions. We have listened and are now well positioned to serve our Italian customers with an extended local-for-local product portfolio and services.” says Nenad Tanasic, Managing Director of MIRECO.
