3M is investing $165 million to improve water quality and reduce water use at its manufacturing facility in Cottage Grove, Minnesota. The investment follows an August 2021 announcement of a companywide collaborative effort to partner with Clean Harbors for waste management, which eliminated the need for 3M’s incinerator to process waste in Cottage Grove. The company has since fully transitioned its waste management at the site, and as a result of discontinuing incinerator operations, reduced its on-site energy use by 25 percent.
