Abstract
The present invention is an improved process for absorbing and decontaminating an organic chemical spill comprising the steps of: partially composting plant material; mixing approximately 80% of the partially composted plant material with approximately 20% of dry plant material; inoculating the mixture with about 50 to 100 parts per million by weight of an organic chemical to form an absorbent; mixing the absorbent with about 20% to 40% by volume of spilled organic chemical; adding water; and allowing the mixture to incubate for a suitable time at ambient temperature until the organic chemical spill is neutralized. The plant material may be cotton gin trash or alfalfa hay; or cotton, legumes, alfalfa, tomatoes or their mixtures. The mixture of absorbent and spilled organic chemical may allowed to incubate in a perforated drum with a lid.
