NewGrass Landscape & Design Uses Safest, Most Eco-Friendly Infill
October 17th, 2008NewGrass Landscape & Design continues to set the standard for safe, eco-friendly synthetic lawn installations in California by refusing to use controversial crumb rubber as infill.
NewGrass Landscape & Design installs NewGrass® synthetic lawns using GreenFill, an environmentally friendly infill alternative, says NGL&D operations director Larry Reno.
The debate over crumb rubber infill is being waged among environmental groups, concerned parent organizations, the rubber industry and some members of the synthetic grass industry. And it’s true that a final verdict is not in.
“There’s not an answer everyone agrees on, but we’d rather err on the side of being responsible when it comes to public health,” Reno says. “That’s the first and main reason we have chosen to stay away from crumb rubber infill.”
The nonprofit Grassroots Environmental Education has been among the strongest voices against crumb rubber infill.
“This crumb rubber is a material that cannot be legally disposed of in landfills or ocean-dumped because of its toxicity,” says Grassroots Environmental Education executive director Patti Wood. “Why on earth should we let our children play on it?”
GreenFill is a conventional granular aggregate that in a more generic form is often used under roadways and railway tracks and in many other applications.
In addition to being safer for children and pets than crumb rubber, and being more environmentally responsible, GreenFill and other alternatives also perform better than crumb rubber on artificial lawns.
“Because it is a heavier raw material than crumb rubber, GreenFill won’t bounce up and out of the grass and into the air as easily as crumb rubber,” Reno says. “Also, it won’t wash away as readily as crumb rubber, especially on sloped terrain.”
According to accepted reports, recycled crumb rubber – usually from used tires – contains chemicals either known or suspected of causing health effects. Used tires are commonly composed in part of ethylene-propylene and styrene-butadiene combined with vulcanizing agents, fillers, plasticizers, and antioxidants in different quantities, depending on the manufacturer. Tire rubber also contains polyaromatic hydrocarbons (PAHs), phthalates, and volatile organic compounds (VOCs).
After extensively studying the available research on crumb rubber use, Janelle Sorensen of the web site Healthy Child Healthy World concluded, “So often we dive into the unknown when we start using new products. We assume that they have been comprehensively tested for safety, but they aren’t required to be. When will we learn our lesson? It’s better to be safe than sorry, so while I’m still unclear about whether recycled tires are safe or not, I’m advocating for a moratorium on its use until we know more.”
In 2007, the nonprofit Environment and Human Health, Inc. (EHHI) commissioned a study to determine whether toxic compounds from crumb rubber could be released into air or water. The EHHI report, Artificial Turf, “definitively confirmed” the irritants benzothiazole and n-hexadecane; butylated hydroxyanisole, a carcinogen and suspected endocrine disruptor; and 4-(t-octyl) phenol, a corrosive that can be injurious to mucous membranes.
The Synthetic Turf Council said in a follow-up statement that the EHHI’s “claims of toxicity are based on extreme laboratory testing such as the use of solvents and high temperatures to generate pollutants.”
“It is clear the recycled rubber crumbs are not inert, nor is a high temperature or severe solvent extraction needed to release metals, volatile, or semi-volatile organic compounds,” said David Brown, EHHI’s director of public health toxicology.
The bottom line is that with the jury still out on crumb rubber and alternatives as good as GreenFill are available, NewGrass Landscape and Design refuses to use crumb rubber infill.
“We want to be the leaders in the artificial grass industry – the environmental leaders, the manufacturing leaders and ultimately the sales leaders,” Reno says. “Using an alternative to crumb rubber that we know is safe for kids and pets, and that works even better than crumb rubber as a synthetic grass infill, is simply the right thing to do. It’s the right thing for the environment and for the safety of the kids and dogs that play on NewGrass®.”
