All asphalt cold patches are not the same. Some asphalt cold patches are made with petroleum distillates that release Volatile Organic Compounds (VOCs) when they are used to repair potholes. Sakrete U.S. Cold Patch asphalt patch is a recycled asphalt product which does not contain petroleum solvent and is the only asphalt cold patch product certified as environmentally preferable by Scientific Certification Systems for Home Depot’s Eco-Option program.
The US EPA has an informative page about Volatile Organic Compounds.
See the Sakrete U.S. Cold Patch “Eco Benefits” page for more details.
