Vinyl Building Products Drive Asbestos Use In USA
Bill Walsh - March 22, 2017
New research from the Healthy Building Network (HBN) documents how vinyl building products, also known as PVC or polyvinylchloride plastic, are the number one driver of asbestos use in the US. These findings were presented to the US EPA last week in a technical report written by HBN Research Director Jim Vallette on behalf of three public health groups. The groups, which represent more than 450 organizations nationwide, submitted comments urging the U.S. Environmental Protection Agency (EPA) to adopt new rules to phase out asbestos under the 2016 amendments to the federal Toxic Substances Control Act (TSCA).
|The vinyl/asbestos connection stems from the fact that PVC production is the largest single use for industrial chlorine, and chlorine production is the largest single consumer of asbestos in the US.  More than 70% of PVC is used in building and construction applications - pipes, flooring, window frames, siding, wall coverings and membrane roofing.  This makes the building and construction industry the single largest product sector consuming chlorine, bearing sizeable responsibility for the ongoing demand for asbestos. ||
Despite the existence of asbestos (and mercury) free chlorine production methods,  the PVC industry has positioned itself at the vanguard of industry efforts to frustrate stronger asbestos regulation. According to Mike Belliveau, the Executive Director of the Environmental Health Strategy Center and a senior advisor to Safer Chemicals Healthy Families coalition, "The PVC market has spurred chemical industry lobbyists to urge the Trump Administration to exempt their use of deadly asbestos from future restrictions." The last time the vinyl industry positioned themselves so publicly on the other side of common sense, they were defending the use of lead in children's vinyl lunch boxes.
Among the findings we have shared with EPA:
The U.S. chlor-alkali industry (Olin/Dow, Occidental, and Westlake/Axiall ) consumed 88% of asbestos imports in 2014, and all asbestos imports in 2016.
Three U.S. chemical companies are importing 1.2 million pounds of asbestos per year for use in 15 chlor-alkali plants. PVC used in building products requires an estimated 250,000 pounds of imported asbestos per year.
- Asbestos miners in Minaçu, Brazil, are literally dying to prop up the U.S. chemical and PVC building product industries' reliance on asbestos. Dozens of asbestos baggers are dying or have died of asbestos related diseases, according to local reports.  Overall, Brazil exports over 13,000 bags of asbestos each year to the U.S. chlorine industry.
Occidental Chemical imported 900,000 pounds of asbestos from Oct. 2013 through 2015, but apparently failed to report those imports to the EPA in possible violation of the Chemical Data Reporting rule as required under TSCA.
Asbestos imports by Occidental Chemical and Olin Corporation more than doubled from 2015 to 2016, perhaps indicating a stockpiling of asbestos in anticipation of further restrictions on mining in Brazil or use in the U.S.
Russia shipped asbestos to Dow in 2014 and to Olin in 2016 (when Olin took over Dow's U.S. chlor-alkali plants). If the mine in Brazil closes, the U.S. chlor-alkali industry's backup plan is the massive mine in Asbest, Russia.
The health hazards of asbestos exposure, painful and deadly lung diseases including cancer, are clear. In our petition to EPA, HBN and its allies urged the agency to take measures within its authority to trigger an asbestos phase out in the chlorine industry. Green building professionals do not have to wait. Do your part to prevent asbestos-related diseases here and abroad. Don't specify vinyl building products.
 In the US more than half of chlorine is produced using asbestos, despite the availability of an alternative production method that does not require either asbestos or mercury.
 According to IHS Markit, "A majority of chlor-alkali capacity is built to supply feedstock for ethylene dichloride (EDC) production. EDC is then used to make vinyl chloride (VCM) and subsequently used to manufacture polyvinyl chloride (PVC). This chain, EDC to VCM to PVC, is normally called the vinyl chain. PVC demand correlates closely with construction spending, therefore, it can be concluded that chlorine consumption and production are driven by the construction industry. Hence, chlorine consumption growth depends on the growth of the global economy, since a country will spend more on construction if it has a healthy gross domestic product." (IHS Markit.
