Weyerhaeuser - Columbus Modified Fiber Facility: Pulp and Paper Plant in Columbus, Mississippi

Weyerhaeuser - Columbus Modified Fiber Facility is a pulp and paper plant located at 371 Manufacturers Dr, Columbus, Mississippi, in Lowndes County. The facility is operational and classified under NAICS codes 322110 (Pulp Mills) and 322299 (All Other Converted Paper Product Manufacturing), indicating a medium-to-large scale operation in the US pulp and paper sector. The facility operates under the US EPA's Clean Air Act, Clean Water Act, and Resource Conservation and Recovery Act, with TRI Section 313 reporting requirements. As a modified fiber facility, it likely uses recycled paper as feedstock, reducing virgin pulp demand. Typical technologies include pulping, bleaching, and paper forming, with wastewater treatment to meet NPDES permit limits. This plant contributes to the regional economy in Columbus and serves as part of Weyerhaeuser's network of fiber-based product facilities. Its environmental significance lies in its use of recycled materials, which lowers landfill burden and reduces energy consumption compared to virgin pulp production, though it still manages air emissions and wastewater discharges under strict regulatory oversight.

Located in Columbus, Mississippi, the facility sits in a region with a humid subtropical climate, where water resources from the Tombigbee River are critical for industrial processes. The pulp and paper sector is inherently pollution-intensive, with primary emissions including volatile organic compounds, particulate matter, and odorous sulfur compounds from pulping. Proximity to residential areas may raise community concerns about air quality and water discharge. The facility's use of recycled fiber reduces some environmental impacts but still requires robust pollution control technologies to comply with EPA standards.
