Building materials with mineral compounds and zeolites can reduce formaldehyde exposure

A new method using minerals in particleboard could significantly reduce formaldehyde emissions indoors.

Formaldehyde, one of the many VOCs (volatile organic compounds) that have been classified as dangerous to human health by organizations such as the World Health Organization (WHO), can be found in the adhesives that are commonly used for gluing particleboard.

According to the US Environmental Protection Agency (EPA), pressed wood products that use adhesives with urea-formaldehyde (UF) resins are one of the most significant sources of formaldehyde in homes.

Formaldehyde emissions reduced

According to an article published in January 2011 on the website ScienceDaily, researchers in Germany have developed a new method using mineral compounds with zeolites that were modified with amino groups to boost adsorption rates.  When they put the zeolite powder into the sample particleboard, they measured a reduction in formaldehyde emissions of 40 percent in both long-term and short-term tests.

This technology could potentially reduce indoor air pollutant levels, the researchers say.
Air purifiers with carbon filter remove VOCs from the air

The development of the mineral compound method is great news for the improvement of indoor air, but until it is commercialized and available for builders and contractors, it’s up to powerful air purifiers with highly adsorbent activated carbon filters to remove VOCs such as formaldehyde from the air.

Electrocorp offers a wide range of commercial and industrial air purifiers for a wide range of applications such as environmental consulting, facility management and mold and asbestos abatement.
