A factory processing US hazardous waste in Mexico has promised to relocate what authorities call its most polluting operations following a Guardian investigation.
The plant in the Monterrey metropolitan area recycles toxic steel dust sent by the US steel industry and recovers zinc, according to that reporting, which was produced in partnership with Quinto Elemento Lab, a Mexico investigative journalism unit. It revealed evidence of heavy-metals pollution in the surrounding neighborhoods.
The factory, Zinc Nacional, has since been contending with inspections and threats of closures by environmental regulators, court actions and media scrutiny. Neighbors have held repeated demonstrations outside the plant, carrying signs with slogans such as Take your mess to the US and Your millions are not worth our lives.
. . .
In a letter to authorities of the state of Nuevo León, the company has now vowed to move its most intensive operations away from its current location in the middle of the Monterrey metropolitan area within two years. It did not specify where to, except that it would be outside the Monterrey metropolitan area and that the company would maintain more than one thousand jobs. It also promised to build a huge enclosure to contain its materials on its existing site, some of which currently sit uncovered, and to plant more trees around its land.
