Abstract
One embodiment of the present invention provides for a biodegradable absorbent material for oil or other hydrocarbon liquid spills. The material consists of a mixture of granulated foam, microbial nutrient, de-dust agent and ground cellulosic material. This mixture is superior to other absorbent mixtures because it biodegrades faster than other mineral or organic adsorbents and is less expensive than synthetic adsorbents on the market today. The material is useful in field operations, plants and shop or even home use. Another embodiment of the present invention, provides for a system for absorbing hydrocarbon based liquids spilled on a surface using the absorbent material described.
Claims9
An absorbent material comprising:
- a mixture of granulated foam, microbial nutrient, de-dust agent and ground cellulosic material, wherein;
- the granulated foam is selected from the group consisting of urea-formaldehyde foam and polyurethane foam,
- the absorbent material is about 6% to about 15% by weight granulated foam,
- the absorbent material is about 0.1% to 1% by weight microbial nutrient,
- the microbial nutrient is a composite material for promoting growth of hydrocarbon degrading microorganisms, comprising:
- a core having water soluble, microbial available nutrients, wherein said nutrients include nitrogen in the form of an ammonium compound, phosphorous in the form of a microbial available phosphate compound, and iron in a form of microbial available iron compound;
- and
- a sacrificial oleophilic, lipophilic, partially oil soluble and biodegradable coating having a saturated fatty acid and an unsaturated fatty acid, wherein said coating encapsulates said core, and the absorbent material is about 79% to 93% by weight cellulosic material.
