Chlorine & Building Materials Project

Chlorine is the origin of many of the world’s most problematic chemicals and products, including polyvinyl chloride (PVC), used in building and construction. There is extensive interest in the building industry in the manufacture and use of chlorine. A necessary first step in reducing the environmental health impacts of chlorine in the supply chain of PVC and other chlorine-based products is to create a public global inventory of chlorine, vinyl chloride monomer, and PVC producers.

Healthy Building Network’s Chlorine & Building Materials project delivers an open access accounting of the technologies, markets, and pollution associated with chlorine production around the world. Phase 1 of this project covers the 86 largest chlor-alkali plants and 56 largest PVC plants in North and South America, Africa, and Europe.  

HBN will complete the global inventory with Phase 2 (Asia) in early 2019.

The Chlorine & Building Materials project is supported in part by subscribers to our Subscription Research program. Current subscribers include: Carnegie, Designtex, Humanscale, Interface, Metroflor/Halstead, and Tarkett.

We seek additional subscriptions to maintain and expand this research in 2019 and beyond. Building product manufacturers and others can support this project through HBN’s Subscription Research program.
