PRP SpillBuster Soy is a unique 100% natural and biodegradable oil spill cleanup tool. It absorbs petroleum hydrocarbons, floats with the contamination on the surface and stimulates indigenous microbes to biodegrade the oil (and itself) into CO2 and water. PRP can be used to remediate contaminated soil as well. Simply sprinkle the PRP powder on the contaminated area and watch it disappear. No residue remains!
