When it comes to human and environmental health, there are few perfect products. It’s hard to name the “best” or the “healthiest” building products. Usually the best we can do is identify healthier products. There are almost always trade-offs.

As the largest consumer of polyvinyl chloride (PVC), the building and construction industry shares a large responsibility for the global pollution unleashed by its production. In HBN’s first research report, Environmental Impacts of Polyvinyl Chloride Building Materials (2002), Dr. Joe Thornton observed, “The hazards posed by dioxins, phthalates, metals, vinyl chloride, and ethylene dichloride are largely unique to PVC, which is the only major building material and the only major plastic that contains chlorine or requires plasticizers or stabilizers.” Although many architecture and design firms, health care systems, product certifiers, and building owners have red listed PVC since Dr. Thornton’s report, global production of PVC continues to rise. This industry’s impacts are growing.
Phase 1 of our Chlorine & Building Materials Project updates Dr. Thornton’s analysis of the impacts of PVC production, from ozone layer depletion to the global distribution of bio-accumulative toxicants, from ocean pollution to fenceline community disasters. In a recent webinar hosted by the Collaborative on Health and the Environment (CHE), I described our findings and their relationships to building products.

Thanks to all who attended our webinar “When is it "green"? Preventing the Toxic Effects of Spray Foam Insulation”!Feb 13, 2017
Spray Foam products marketed as being healthier may be formulated without some of the hazardous chemicals traditionally found in SPF products, but don’t replace the really bad actor chemicals. SPF insulation - even those with improved formulations - remain at the bottom of our Stoplight chart, in dark red. (Updated, April 4, 2017.)Jun 16, 2016
As temperatures rise on ballfields across America, so do concerns over the piles of tire waste upon which children play. Synthetic turf playing fields lie atop heaps of finely ground recycled rubber from old tires. In playgrounds, chopped up tire mulch is becoming as common as dirt. In the United States between 2007 and 2013, enough ground ti...

Earlier this year, one last piece of light density residential fiberglass insulation bearing formaldehyde-based binder rolled off a production line somewhere in the Midwest United States. Then the line stopped, and a new binder came on line. As of October 2015, every fiberglass insulation company in the United States and Canada has phased out...

March 17th marks the 10th anniversary of the EPA order that made it illegal to use the arsenic-based pesticide CCA (chromated copper arsenate) to treat wood intended for most residential uses, including wood destined for decks, picnic tables, landscaping timbers, gazebos, residential fencing, patios, walkways and play structures. This is also a hap...
