CEMEX, a Mexican multinational building materials company, completed the acquisition of a 53% stake in ProStein, a German aggregates company. Financial terms were not disclosed. "We are strongly committed to making the right investments for our customers and shareholders. This investment allows us to have a sustainable supply of high-quality aggregates in a major metropolitan center for years to come, in line with our Operation Resilience strategy. It is also key for our plans to significantly increase the volume of construction and demolition waste that we recover, recycle, and reuse in our operations," Sergio Menendez, CEMEX President of Europe, Middle East, Africa & Asia.
