Paper Mills and Factories: Wisconsin Asbestos Exposure Legacy
How Fox River Valley paper mills and Milwaukee manufacturing exposed generations of Wisconsin workers to asbestos.
Wisconsin’s position as the state with the highest per capita mesothelioma rate in the country traces to two industrial corridors that defined the state’s economy for more than a century: the Fox River Valley paper mills and Milwaukee’s manufacturing base.
The workers who operated the paper machines, maintained the steam systems, and built the ships are the ones receiving diagnoses now, decades after the mills closed or modernized. Their exposure was not incidental. It was embedded in every shift. For those now facing a diagnosis, the current treatment landscape offers options that were not available when these workers were first exposed.
The Fox River Valley Paper Corridor
The Fox River runs from Lake Winnebago northeast to Green Bay, passing through Appleton, Neenah, Menasha, Kimberly, and Kaukauna. For most of the 20th century, this 30-mile stretch contained more paper mills per square mile than anywhere else in the world.
Companies including Kimberly-Clark, Consolidated Papers, Appleton Papers, and dozens of smaller operations lined the river. The mills produced everything from fine writing paper to tissue to industrial packaging.
Asbestos was integral to the papermaking process. The fabric belts that carried pulp through the machine, known as paper machine felt, contained asbestos fibers for heat resistance and durability. Workers who installed and replaced these felts handled asbestos-containing material directly. Dryer rolls, the heated cylinders that dried the paper sheet, were insulated with asbestos, and maintenance crews who serviced these rolls stripped and replaced insulation as part of routine schedules.
Paper mills run on steam. Every pipe carrying steam from the boiler house to the machine floor was wrapped in asbestos insulation, and pipefitters, insulators, and maintenance workers cut, fit, and replaced this insulation throughout their careers. Pumps, valves, and flanges throughout the mill used asbestos gaskets to withstand heat and pressure, and millwrights replaced these components regularly. Heavy production equipment, including winders, calenders, and conveyors, used asbestos brake pads. Mechanics who serviced this equipment released fibers into the air with every brake job.
Milwaukee Manufacturing
Milwaukee’s industrial base operated independently from the paper corridor but created its own dense web of asbestos exposure. The city’s manufacturing sector encompassed automotive parts, heavy machinery, engines, foundries, and electrical equipment. The auto parts production in Milwaukee paralleled the exposure seen in Detroit’s Big Three assembly plants and Ohio’s Toledo corridor, where brake linings and clutch facings created the same occupational hazards.
Major employers including A.O. Smith, Allis-Chalmers, Briggs and Stratton, and Harnischfeger all operated facilities where asbestos insulation, gaskets, and fireproofing were standard. Workers in these plants handled asbestos-containing materials daily, often without protective equipment or awareness of the risk.
The city’s breweries, including Pabst, Schlitz, and Miller, also used asbestos in their steam systems, refrigeration insulation, and facility infrastructure.
Lake Michigan Shipyards
Shipbuilding on the Great Lakes exposed a smaller but heavily impacted workforce. Manitowoc Shipbuilding Company built submarines and surface vessels during World War II. Sturgeon Bay shipyards constructed Coast Guard cutters and commercial vessels. Milwaukee’s port facilities handled ship repair and maintenance.
Shipyard workers faced some of the most concentrated asbestos exposure of any occupation. Pipe insulation, boiler lagging, fireproofing, gaskets, and electrical insulation all contained asbestos. Workers in enclosed below-deck compartments breathed fiber-laden air throughout their shifts. The same conditions were documented at shipyards in Savannah, Georgia and along the Florida Gulf Coast.
Take-Home Exposure
Like workers in other industrial states, Wisconsin’s paper mill and factory workers carried asbestos fibers home on their clothing. Spouses who laundered work clothes and children who greeted their parents at the door were exposed to the same material that was accumulating in workers’ lungs.
Recent legal cases across the Midwest have recognized take-home exposure as a valid basis for claims. In January 2026, the Virginia Supreme Court affirmed a duty of care for shipyard take-home exposure, a ruling that strengthens the legal foundation for secondary exposure claims nationwide. Families affected by secondhand exposure may have both lawsuit and trust fund options.
If you or a family member worked in a Fox River Valley paper mill, Milwaukee manufacturing plant, or Great Lakes shipyard, an experienced mesothelioma attorney can help reconstruct the exposure history. Employment records, union documents, and product databases can identify which asbestos-containing products were used at specific facilities.

Frequently Asked Questions
Which paper mills in Wisconsin used asbestos?
Virtually all of them. Paper mills across the Fox River Valley, including those operated by Kimberly-Clark, Consolidated Papers, Appleton Papers, and others, used asbestos in paper machine felt, dryer roll insulation, steam pipe covering, gaskets, and brake systems. The material was standard in the industry through the 1970s.
What jobs in paper mills had the highest asbestos exposure?
Pipefitters, insulators, and millwrights had the heaviest direct exposure from installing and replacing asbestos insulation and gaskets. Machine operators, maintenance crews, and electricians were also exposed through proximity to asbestos materials during daily operations.
Were Milwaukee breweries asbestos exposure sites?
Yes. Major Milwaukee breweries including Pabst, Schlitz, and Miller used asbestos in steam systems, refrigeration insulation, and building infrastructure. Workers who maintained these systems were exposed to asbestos fibers.
Can I file a claim if the paper mill is closed?
Yes. Most asbestos claims target the manufacturers of the asbestos-containing products, not the mill itself. Many of these manufacturers have established bankruptcy trust funds. An attorney can identify which trusts apply based on the specific products used at your workplace.
Can I remove asbestos myself in Wisconsin?
Wisconsin regulations under Wis. Adm. Code ch. NR 447 generally exempt single-family homes or structures with four or fewer dwelling units from DNR asbestos notification and removal rules for demolition or renovation, allowing homeowners to handle small amounts themselves. However, the state requires asbestos removal and disposal to be performed by licensed, certified persons, and multiple agencies strongly advise against DIY efforts due to risks of fiber release, contamination, and long-term health effects like mesothelioma. Professional abatement uses mandatory wet methods, HEPA filtration, containment, and DNR-approved disposal to comply with regulations.
Can I look up if my house has asbestos?
Visual inspection alone cannot confirm asbestos in your home, as asbestos fibers are invisible to the naked eye. However, you can look for risk indicators such as the age of your home (built before the 1980s), common locations like textured ceilings, vinyl floor tiles, pipe insulation, and building records that may document asbestos use. The only definitive way to identify asbestos is through professional laboratory testing, where a certified inspector collects material samples and sends them to a lab for analysis using methods like Polarized Light Microscopy or Transmission Electron Microscopy. The U.S. Environmental Protection Agency recommends testing if building materials are damaged or you plan to remodel, as disturbing materials can release fibers into the air. Do not attempt to collect samples yourself, as improper handling can release asbestos fibers.
How much does it cost to remove asbestos in Wisconsin?
Asbestos removal costs in Wisconsin average $20 to $65 per square foot, with most homeowners spending $1,200 to $3,000 for typical projects. Interior removal generally costs $5 to $20 per square foot, while exterior work such as roof removal runs $50 to $120 per square foot. For a full home remediation including walls, ceilings, and attic, costs can reach $15,000 or more. An alternative to removal is encapsulation, which seals asbestos in place and costs $2 to $6 per square foot. Wisconsin also charges permit fees ranging from $135 to $1,350 depending on the amount of regulated asbestos-containing material involved.
How much does it cost to have your ceiling tested for asbestos?
The cost to test a ceiling for asbestos, typically via bulk sample lab analysis of materials like popcorn texture, ranges from $250 to $750 per inspection, with national averages around $450 to $483. Air testing around disturbed ceiling materials costs $200 to $800, while dust sampling runs $120 to $180 including lab fees. Lab analysis alone for a submitted ceiling sample starts at $22 per sample or layer. Costs vary by location, home size, number of samples, and professional versus DIY kits ($30 to $80 plus $40 to $150 lab fees).
