History of 3M in Decatur

  • Icon of clock with time going backwards.

    The 3M plant in Decatur is an integral part of the Decatur-Morgan County business community and the growth of the north Alabama region – one of the fastest growing economies in the U.S. The company launched its Decatur operations in 1961 with the establishment of a plant producing certain chemistries. The following year the film plant began operations on the same site.

    The site production portfolio expanded again in 1997 with the establishment of a joint venture between 3M's fluoroelastomer business with German company Hoescht to form Dyneon. Decatur was the key producer of the 3M products involved in the venture. In 1998, Dyneon built its own facility on the Decatur site for production of these materials. In 1999, 3M purchased Dyneon from Hoescht

    Today, the 3M footprint in Decatur covers 848 acres and includes more than 2.5 million square feet under roof.

Production Lines and Technology

Despite representing largely separate businesses, the Film and Materials plants on the 3M site in Decatur enjoy a vibrant synergy. Each plant has its own manufacturing organization headed by a plant manager, one of whom also serves as site manager. The site manager oversees resources of common benefit to the plants. These include Environmental, Health, Safety and Regulatory (EHS&R), as well as Human Resources, Supply Chain, Information Technology, Wastewater Treatment, and Utilities. Specific operational groups such as Engineering, Production, Maintenance, and Quality Assurance are managed separately by each plant.

    The Materials Plant

    The Materials Plant is composed of several key value streams – batch chemicals, fluoroelastomers and fluoroplastics. Products include a wide variety of adhesives, curatives, fluoropolymers, primers, processing additives, protective treatments, specialty chemicals and surfactants. In addition to manufacturing, the Materials Plant also has a process development center for new fluoropolymer products.

    The Film Plant

    The Film Plant manufactures products that can be divided into two key value streams : specialty resins and specialty films. The specialty resins are used in the film manufacturing processes to produce the specialty films. These resins have unique optical and thermal properties. The specialty films can be used in numerous applications. Three major categories are Reflective Polarizer Applications, Polyester Applications, and Extrusion Coated Films.

    Technology At Work

    Our success begins by applying our 50 core technologies – often in combination – to a long list of real-world customer needs in our manufacturing facilities. Much of the fundamental research and development for both the Film and Materials Science Division is performed in our St. Paul R&D facilities; however, more than 15 of the 50 core 3M technologies are practiced and continuously improved at the Decatur location.

Environmental Stewardship

  • Icon of a building with a leaf inside of it.

    3M is taking action to manage legacy materials at our sites with a commitment to environmental stewardship. As a company, we recognize the questions around PFAS and our manufacturing processes. 3M continues to lead through innovative solutions to meet our goals while investing $1 billion in water reduction and improving water quality. It is a corporate commitment we are putting into action each day. Environmental stewardship at our manufacturing sites like Decatur support the company’s goal of reducing our water usage across the company by 25 percent by 2030. Through these efforts, 3M expects to reduce its overall water usage globally by 2.5 billion gallons per year.

    Locally, 3M and the Alabama Department of Environmental Management (ADEM) announced an Interim Consent Order agreement in July 2020 to address previously disclosed PFAS discharges at the Decatur facility. As scientific knowledge of PFAS has advanced, so has 3M’s approach to managing and disposing of these substances. We are committed to working collaboratively with our community to address our activities and promote environmental stewardship for the future. For more information about the Interim Consent Order and read the most recent status report, please click here. View ADEM Report.

3M has implemented changes that are state-of-the-art practices for PFAS management of our site with ADEM’s engagement. Recent updates at the Decatur site include:

  • Design and installation of an additional state-of-the-art granular activated carbon (GAC) technologies to help prevent PFAS from entering the environment. These complement the two advanced water treatment systems currently operating at the Decatur facility to remove PFAS from process wastewater and groundwater.
  • Installation of a closed loop non-contact cooling water recycling system that has reduced the volume of the 3M Decatur facility’s water consumption by more than 70 percent.
  • Development of a wastewater minimization plan to further reduce PFAS discharge to the wastewater treatment plant. The plan includes a prioritized list of projects designed to minimize discharge of PFAS from process and cleaning operations. The plan was approved by ADEM in late 2021. 3M is currently implementing the projects covered by the plan.

3M reports on our progress to ADEM through semi-annual progress updates. Read the most current update to ADEM here.

3M has several on and offsite investigations in progress, including:

  • The Avenue A ditch remediation project plan was approved by ADEM in early 2022. The plan involves installing a ditch liner and equipment underneath it to collect groundwater with PFAS and prevent it from draining to Bakers Creek. The water is then pumped to the plant’s water treatment system. Construction is expected to begin in 2023.
  • A facility and adjacent areas investigation, which involved studies and sampling of soil and groundwater to better understand the presence and transport in these medias on and offsite. This plan was submitted to ADEM in mid-April 2022.
  • The former Brookhaven Middle School campus in Decatur, currently being evaluated in collaboration with ADEM for future use and monitoring. We anticipate submitting the investigation report in early 2024.

Looking to the future, 3M has projects and studies on the horizon, including:

  • In spring 2022, 3M submitted a pilot study to ADEM based on a fall 2020 feasibility study related to the evaluation of approved wastewater control technologies. Feedback from ADEM on the study is expected later in 2022.

3M remains committed to continuing our work in environmental stewardship with ADEM, the U.S. Environmental Protection Agency, and the community. 3M is also taking action to identify, investigate and perform appropriate remediation of legacy contamination of soil and groundwater at sites where PFAS from the facility may have been disposed. To date, 3M has invested more than $100 million to address PFAS at the Decatur facility, including a significant cap and containment project to manage PFAS-impacted soil and groundwater, and the installation of a granular activated carbon system to remove PFAS from ground water.
