US: Cemstone celebrated the opening of a new concrete plant in Owatonna, Minnesota on 5 October 2023, when it hosted an open house and ribbon cutting ceremony. Located in an out-of-town industrial park with good highway connections, the new plant has replaced an aging facility that stood much closer to downtown Owatonna, according to the Owatonna People's Press newspaper.

The plant can produce around 190m3/hr of concrete, compared to 84m3/yr at the old facility. General Manager Ken Kuhn said the loading chute at the new site can turn concrete trucks around in three minutes, as opposed to eight minutes before. The plant also features ramps that allow trucks to dump loads of aggregate directly into five large outdoor hoppers, each with a 35t. The previous facility had just one hopper and aggregate had to be transported from a stockpile across the street.

The new plant also features a water recycling system, which Kuhn said is a rarity in the concrete business. Cemstone trucks will return wash water from job sites to the plant, where it will pass through a series of bays to filter out debris and sediments. Once clarified, that water will be used to wash the truck, before being recycled again. The facility will also collect all the process water it produces and approximately half the rainwater from the site for reuse.
