W.R. Grace & Co.
W.R. Grace & Co. established a trust fund to compensate people after facing lawsuits over its asbestos-containing products and contaminated Libby mine. Asbestos litigation forced the company to file for bankruptcy in 2001. Two trusts were formed in 2014 to settle asbestos claims.

W.R. Grace’s Connection to Asbestos
W.R. Grace has a long history of using asbestos in its products, including cement, plaster, fireproofing spray and surface materials. W.R. Grace also mined vermiculite in Libby, Montana. The mines were contaminated with asbestos, which is the main cause of mesothelioma.
The company bought the Zonolite Company in 1963 and ran a processing plant in Easthampton, Massachusetts from 1963 to 1992. After that, the site was rented to JPS Acquisition Elastomerics until 2000. W.R. Grace had to clean up the soil at the site since the vermiculite work had polluted it. In April 2001, the company filed for bankruptcy protection.

In 2005, W.R. Grace and its top leaders were charged with hiding the health risks of asbestos in Libby and slowing cleanup efforts. Records showed they knew about the dangers since the 1970s. In 2009, a jury found them not guilty. Many in Libby were disappointed, blaming limits on evidence and the timing of the mine’s closure.
“A human and environmental tragedy has occurred in Libby,” said William W. Mercer, U.S. Attorney for the District of Montana, Department of Justice, in a 2005 statement. “This prosecution seeks to hold Grace and its executives responsible for the misconduct alleged,” Mercer stated.
Who Was at Risk of Asbestos Exposure From W.R. Grace?
Many workers who handled raw materials for W.R. Grace or used its products were exposed to asbestos on the job. This puts them at a higher risk of developing mesothelioma or other asbestos-related diseases. W.R. Grace workers were in mines, mills and factories, while some also moved vermiculite and other asbestos products for the company.
People who worked in home improvement and used W.R. Grace products were also at a higher risk of asbestos exposure. Those who installed insulation or used Zonolite insulation in their homes could be exposed.

People who lived, worked or went to school near the Libby mine or W.R. Grace’s factories were also exposed to asbestos from pollution in the air.
More than 2,000 miles from Libby, people in New York City were exposed to W.R. Grace’s asbestos products in the north tower of the World Trade Center. First responders and survivors of the 9/11 attacks faced health threats from Zonolite Mono-Kote, a spray-on fireproofing that contained asbestos.

Mesothelioma lawsuits against W.R. Grace sought compensation for medical expenses and lost wages. As legal actions mounted, the company eventually declared bankruptcy to end litigation against it. Through the bankruptcy process, the company established asbestos trust funds, which began accepting claims in 2014.

The company will pay the amount plus interest over 10 years.

A Montana jury awarded Hutt $36.5 million in 2022. They agreed the company’s workers’ comp provider failed to ensure safety.
W.R. Grace Asbestos Trust Funds
The company filed for bankruptcy in April 2001 to deal with more than 129,000 claims from people with mesothelioma, lung cancer and other asbestos-related diseases. In 2008, W.R. Grace shared a plan to settle with those involved. That plan included the creation of an asbestos trust fund. After some changes, the plan was approved, and W.R. Grace officially emerged from bankruptcy on February 3, 2014.
As part of the plan, the WRG Asbestos PI Trust was created. It pays people who got sick from mesothelioma and other asbestos-related diseases. The trust was initially funded with $3 billion available to claimants.
