Natural linoleum is a durable, low-maintenance flooring made from linseed oil, pine rosin, sawdust, cork dust, limestone, natural pigments, and a jute backing—all minimally processed and commonly available materials. Linoleum does not contain significant petroleum-based products or chlorinated chemicals, as does vinylCommon term for polyvinyl chloride (PVC). In chemistry, vinyl refers to a carbon-and-hydrogen group (H2C=CH–) that attaches to another functional group, such as chlorine (vinyl chloride) or acetate (vinyl acetate). (PVC) flooring—which is often mistakenly referred to as "linoleum." The ongoing oxidation of linoleic acid in the flooring leads to offgassing of volatile organic compounds (VOCsVolatile organic compound. An organic compound that evaporates readily into the atmosphere; as defined by the U.S. Environmental Protection Agency, VOCs are organic compounds that volatize and then become involved in photochemical smog production.) that taper off over time, but some argue that linoleum's VOCs, as compared to petroleum-derived VOCs, are a lesser health threat. Recycled-tire rubber provides a highly durable, resilient, slip-resistant, anti-fatigue surface suitable for a variety of flooring requirements. Rubber granules from ground tires may be vulcanized (reformed under high heat using a sulfur additive), or agglomerated with a synthetic binding matrix, such as polyurethane. The rubber and its binders or additives, however, may be significant sources of indoor air pollutants, including VOCs and heavy metals; actual emissions vary widely from product to product. Thus, rubber flooring isn't recommended for most indoor spaces unless there is evidence of low emissions. Indoor/outdoor spaces, such as entrances and skating rinks, or commercial/industrial areas with high ventilation rates, are potentially excellent applications for these recycled-content products.
