The Road to Optimizing Asphalt Pavement Recycling

Wes Sullens and Jim Vallette - March 29, 2017

Today the Healthy Building Network and StopWaste released the sixth and final report in our Optimizing Recycling initiative: Reclaimed Asphalt Pavement (RAP) in Building & Construction.   Reclaiming and reusing asphalt has many benefits, including waste prevention, reduction of greenhouse gas emissions, and lower lifecycle impacts compared to virgin asphalt material use.   Tremendous life cycle benefits come from maximizing the use of reclaimed asphalt pavement and minimizing the use of virgin asphalt. Cold-in-Place recycling, the rarest form of asphalt pavement recycling, can reduce carbon dioxide emissions by as much as 95 percent per lane mile and save a lot of money ----  as much as 40 percent compared to conventional techniques. More common warm mix asphalt can reduce carbon dioxide emissions by 15 percent compared to conventional paving, and increase proportions of RAP used. In our report, we provide... Read More

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. [1] More than 70% of PVC is used in building and construction applications - pipes, flooring, window...

Perkins + Will Adds Antimicrobial Products to Precautionary List

Bill Walsh - March 1, 2017

Following the lead of the Centers for Disease Control and Prevention, the Food and Drug Administration, and other credible institutions, the global architectural firm of Perkins+Will is placing Products Marketed as Antimicrobial on its Precautionary List. The firm's decision was made after an exhaustive review of available information about the use of antimicrobial substances in building products conducted by Healthy Building Network researchers. Perkins+Will project teams will advise clients of reasonable alternatives where appropriate.   After extensive review that has spanned over 7 years, [1] HBN researchers were not able to turn up any evidence documenting health benefits associated with the use of antimicrobial products in building materials. These findings are published in a new white paper entitled Healthy Environments: Understanding Antimicrobial Ingredients in Building... Read More

PVC’s Asbestos & Mercury Problems

Bill Walsh - October 3, 2016

For those of you attending Greenbuild this week, I cordially invite you to my Wednesday morning panel, Let's Talk About PVC. Join me in conversation with a group of experts who have highly divergent views on the topic of whether polyvinylchloride plastic (PVC) is a green building material. For those of you who cannot attend, consider this: Asbestos is an essential component of chlorine, and therefore, PVC production in the USA. [1] According to IHS Markit, "Chlorine consumption and production are driven by the construction industry." [2] PVC demand correlates closely with construction spending. Chlorine is the main ingredient (60% by weight), the "C" in PVC.   Visit HBN at Booth Number 1629.     Wednesday, October 5: HBN Founder & President will speak on the panel "Let's Talk About PVC" from 8:00 to 10:00 AM Session: A13, Room 501 ABC   Thursday, October 6: HBN Board...
