Building materials company Vulcan Materials Company (VMC) in Birmingham, Ala., produces and supplies construction aggregates primarily in the United States. The company operates through its four broad segments: Aggregates; Asphalt; Concrete; and Calcium.
Recently, Mexican President Andres Manuel Lopez Obrador stated that the country would go to local and international courts if an agreement could not be reached with VMC over its mining activity in the Quintana Roo state. In May, the Mexican government shut down the company’s operations on concerns about the effects of its underwater limestone extraction on the environment and water table. President Lopez Obrador has described VMC’s limestone extraction methods as an “ecological catastrophe.”
