The Paris-based parent company of the Lafarge facility along the West Seattle shore of the Duwamish River is merging with another global cement giant, Holcim. The “merger of equals” was announced in Europe early today, three days after the companies disclosed they were talking about joining forces. No Washington state holdings for Holcim, according to its website. Too soon to say what it might mean for local facilities like this one, aside from the company changing its name to LafargeHolcim. Given the size of the merger, regulatory approvals aren’t expected until next year at the earliest.
