Abstract
The present invention relates to a novel chemical composition for removing oil from asphalt shingles. The composition preferably comprises approximately 48% water, 48% fuel such as gasoline or diesel, 2% alcohol, 1.5% citrus and 0.5% enzyme by weight. The composition is used in a system comprising a plurality of tanks that operate under a controlled heat and pressure to breakdown oil components within the shingles. The system uses a closed loop process to feed back the residual ingredients of the composition for reuse. Once through the system, the oil is removed from the asphalt shingles, thereby preventing oil from leeching into the groundwater when the asphalt shingles are disposed of.
