Home Depot today announced a chemical hazard avoidance policy that will prohibit numerous toxic chemicals in paints, carpeting, flooring and fiberglass insulation products.

The Home Depot Chemical Strategy, included in its 2017 Responsibility Report, targets a range of chemicals known or suspected to cause cancer, mimic and disrupt hormone systems, and impair brain function. The retailer’s policies, for certain product categories, far exceed the chemical restrictions of LEED and most product certifications in these categories. The world’s largest retailer of building products credited HBN’s “guidance on priority chemicals and innovation” as it adopted many of the recommendations made by HBN and other environmental health groups in a dialogue begun in 2014.

By applying its chemical strategy to all products in target categories, Home Depot makes important strides toward equity in the green building movement. It tracks many of the recommendations HBN provides to the affordable housing community in our HomeFree initiative. Because it impacts products at all price points, not just premium products and not just those that qualify for the retailer’s Eco-Options program, the policy ensures that all contractors and do-it-yourself customers get healthier products regardless of the brand purchased, and regardless of whether or not the product has been certified “green.” One of the qualifying products, a flat sheen paint, is the first “zero VOC” paint priced under $20 per gallon.[1] “We’re not just sourcing new healthier products, we are striving to improve our current assortment of the products we already sell,” Ron Jarvis, Home Depot Vice President of Merchandising and Sustainability, told HBN.

Home Depot’s most significant advances are in reducing toxic hazards in carpets and paints. The new carpet policy implements two major recommendations of HBN’s newest report, Eliminating Toxics In Carpet: Lessons For The Future of Recycling. published last week. As we reported, Shaw Industries – the country’s largest carpet manufacturer – recently stopped using fly ash from coal-fired power plants as filler. Today, Home Depot announced that fly ash, which contains toxic heavy metals, is “excluded from indoor wall-to-wall carpet in our U.S. and Canada stores.” Home Depot also announced its carpet does not contain several other chemicals that HBN has prioritized for elimination, including ortho-phthalates and organotins used in carpet backings.

Home Depot will also eliminate a class of toxic chemicals from paints called alkylphenol ethoxylates (APEOs). These chemicals, which are present even in low VOC paints, are surfactants, which help different types of material mix together well, and are coming under increased scrutiny as hormone disrupting chemicals with health effects ranging from breast cancer, reproductive disorders and obesity. They are mostly phased-out in Europe and Japan, but still common in the U.S., even though the EPA has identified over 200 “safer surfactants” to replace them.[2]

Today’s announcement is the next step on a long road that started with Home Depot’s 2015 move to eliminate phthalates from vinyl flooring. Much work lies ahead. For example, the company noted that it was not removing methylene chloride paint strippers from its shelves, a major objective of the national consumer campaign Mind The Store. The retailer’s hazard avoidance policy does not address some important problems even within the building product categories in its scope, and does not apply to many other high-impact building product categories. Regrettably, full public disclosure of all product ingredients is not required.

However, the hazard avoidance approach of the Home Depot Chemical Strategy signals fundamental, permanent and systemic improvement in the building products industry, and is a strong step towards health equity in building products. It leans toward a future when “healthy products” are not sold for a premium or as specialty items, and any product on the shelf meets the reasonable consumer expectations that it is healthy for people and our planet.

Healthy Building Network’s report on post-consumer carpet feedstocks calls for eliminating over 40 highly toxic chemicals in carpets that threaten public health and impede recycling. These toxics are known to cause respiratory disease, heart attacks, cancer, and asthma, and impair children’s developmental health.

The report outlines strategies to protect public health and the environment by improving product transparency, eliminating dangerous chemicals from carpets, and increasing carpet recycling rates. It also reveals surprising efforts in the industry to remove many of these toxic substances from carpet design.

Building products incorporating antimicrobial additives are becoming increasingly prevalent. Paints, and other touchable surfaces such as countertops, and virtually any product considered as an interior finish may contain one or a combination of antimicrobials. These agents are considered pesticides, but their identity—and related hazards—can be difficult for the average person to discover. This lack of transparency creates a hurdle for the informed selection of products with reduced negative impacts.

No evidence yet exists to demonstrate that products intended for use in interior spaces that incorporate antimicrobial additives actually result in healthier populations. Further, antimicrobials may have negative impacts on both people and the environment. This paper, prepared by Perkins&Will in partnership with HBN, aims to present current information about reported or potential health and environmental impacts of antimicrobial substances as commonly used within the building industry, and to assist architects, designers, building owners, tenants, and contractors in understanding those impacts.

In response to growing concerns over COVID-19, Healthy Building Network (HBN) and global architecture and design firm Perkins and Will reexamined and reaffirmed the conclusions and recommendations of this white paper.

Asphalt (also known as asphalt concrete, bitumen, or road tar) is the most common paving material by far, accounting for a 92 percent share of the 2.5 million miles of roads and highways in the United States. 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.

Keys to increasing the recycling of asphalt and its attendant environmental benefits include simplifying the designs of asphalt mixes, reducing toxic additives in production, tracking materials from production through use and recycling, testing incoming materials for contaminants, and avoiding the addition of cutback solvents and other toxic rejuvenating agents.

Research from 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.

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 frames, siding, wall coverings and membrane roofing. [2] This makes the building and construction industry the single largest product sector consuming chlorine, bearing sizeable responsibility for the ongoing demand for asbestos. [3]

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 HBN’s Findings:

  • The U.S. chlor-alkali industry (Olin/Dow, Occidental, and Westlake/Axiall [4]) 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. [5] 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. 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.

3. 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. “Chemical Economics Handbook: Chlorine/Sodium Hydroxide (Chlor-Alkali),” December 2014. https://www.ihs.com/products/chlorine-sodium-chemical-economics-handbook.html)

Healthy Building Network’s research into current recycling practices for flexible polyurethane foam (FPF) indicates that most post-consumer feedstocks are contaminated with highly toxic flame retardants.

Discussions of recycling FPF have centered around the human health and environmental hazards posed by the flame retardant PentaBDE, which the foam industry phased out a decade ago. But the flame retardants that have replaced PentaBDE present similar concerns. Manufacturers incorporate flame retardant-laden post-consumer FPF into new products, primarily bonded carpet cushion. Recycling and installation workers and building occupants, particularly crawling children, can be exposed to these toxic chemicals. The recent emergence of pre-consumer FPF scrap that is free of flame retardants is a great step toward a safer, more valuable feedstock, but more work is needed to track and label flame retardant-free FPF to ensure that future post-consumer foam is also flame retardant-free.

When one waste disposal option closes, another inevitably opens.

A half-century ago, the federal government started regulating solid wastes and preventing rampant dumping in the woods, ocean, and unlined dumps. Then the so-called Not-In-My-Backyard (NIMBY) movement of the 1970s and 1980s prevented scores of landfills and incinerators from being permitted across the country, just as existing disposal sites were reaching capacity. There were also spectacular failures at waste sites that made headlines. Coal ash ponds failed, releasing contaminated waste into rivers and drinking water. Giant piles of tires caught on fire, and came to symbolize the crisis of growing piles of waste. 

In response, environmental agencies partnered with waste generators like the coal power and tire industries to find ways to reduce the amount of their wastes going to landfills. The US Environmental Protection Agency developed an option called “beneficial use,” in which these wastes could be diverted to build roads, fill old mines, and turn wastelands into golf courses. Some of these “beneficial uses” hit literally close to home; coal waste has been diverted into wallboard and carpet backing, tires into flooring, and contaminated soils into our own backyards, without any regulation.

In two articles, we describe the impacts of this waste management strategy.

 “On Tire Wastes in Playgrounds” reveals how chopped up tire mulch is becoming as common as dirt in playgrounds, and why government health agencies are beginning to take action to protect children from exposure to toxic substances in the rubber waste, like polycyclic aromatic hydrocarbons and lead.  

 “Filled with Uncertainty: Toxic Dirt in Building & Construction” examines the unregulated dirt trade. Our research found that soil and coal ash contaminated with neurotoxic substances have become commonplace construction materials, from structural fill to flower bed topsoil. Contaminated material is often sold as “clean fill” by untrustworthy companies. With no tracking in place, building owners have no idea, and probably don’t think to ask, where their fill is coming from.

Waste has a way of finding the path of least resistance. A void of oversight coupled with numerous government and private sector incentives promoting the use of unregulated recycled content leaves it to responsible architects, designers, contractors and building owners to increase scrutiny of this vast diversion of wastes into our homes, schools, playgrounds and places of business. In the absence of political will, building owners and residents are left to protect themselves. We hope these articles will lead developers, especially of residential areas and playgrounds, to start asking more questions of dirt and fill contractors, beginning with: where did your materials come from, and have they been tested for toxic contaminants?

The recycling industry has made significant strides toward a closed loop material system in which the materials that make up new products today will become the raw material used to manufacture products in the future. However, contamination in some sources of recycled content raw material (“feedstock”) contain potentially toxic substances that can devalue feedstocks, impede growth of recycling markets, and harm human and environmental health.

Since May 2014, the Healthy Building Network, in collaboration with StopWaste and the San Francisco Department of Environment, has been evaluating 11 common post-consumer recycled-content feedstocks used in the manufacturing of building products. This paper is a distillation of that larger effort, and provides analysis on two major feedstocks found in building products: recycled PVC and glass cullet. This research partnership seeks to provide manufacturers, purchasers, government agencies, and the recycling industry with recommendations for optimizing the use of recycled content feedstocks in building products in order to increase their value, marketability and safety. This report was prepared in support of a research session at the 2015 Greenbuild conference in Washington, DC.

New HBN research reveals that legacy toxic hazards are being reintroduced into our homes, schools and offices in recycled vinyl content that is routinely added to floors and other building products. Legacy substances used in PVC products, like lead, cadmium, and phthalates, are turning up in new products through the use of cheap recycled content.

Funding for research on post-consumer PVC feedstock was provided by StopWaste and donors to the Healthy Building Network (HBN). It was conducted using an evaluative framework to optimize recycling developed by StopWaste, the San Francisco Department of the Environment, and HBN. This briefing paper on post-consumer recycled PVC is a prequel to a forthcoming white paper by this new collaboration.

Source separation of waste streams and toxic content restrictions are crucial actions toward optimizing the value of recycled feedstocks in building products. HBN’s research on glass waste – known as cullet – reveals the multitude of economic and environmental benefits of these practices.

The ability of fiber glass insulation manufacturers to incorporate cullet increases; the wasteful landfilling of discarded glass (nationally, only 28% is recycled) decreases. Manufacturers need less energy to produce insulation, leading to lower greenhouse gas emissions. Workers, surrounding neighborhoods, and the environment at large are exposed to fewer toxic contaminants. Post-Consumer Cullet in California is the second in a series of Healthy Building Network reports for the Optimizing Recycling collaboration.
