Osorb is an absorbent nano-engineered glass useful for capturing petroleum hydrocarbons and other organics, allowing biological degradation to occur in the soil in stormwater systems.
Specialised, reductive Osorb materials have been modified to both capture and break down a wide spectrum of volatile organic compounds (VOCs) and other contaminants, including:
Iron-Osorb removes contaminants such as oil, gas, pharmaceuticals, pesticides, and nutrients from stormwater. It also improves plant growth by breaking down contaminants in soil and protects healthy soil microbes from toxicity overloading.
In the side-by-side stormwater control study above, an Osorb-enhanced swale (bioretention system) that contains soil with 1% Iron-Osorb was placed next to a control swale with identical runoff conditions. Both swales reduce stormwater volume by >95%. The Osorb swale showed no signs of nutrient leaching in comparison to the evident nutrients in the control swale’s effluent.
