If it is an oil spill on land, a diesel truck going off the road for instance, you can dig the absorber into the ground, as deep as the oil has penetrated, and the absorber will pick up the oil and over a period several months it will turn the oil and saturated absorber into clean soil again. It is natures way of composting material and our absorber, with its unique properties, is one of the very limited ways you can do it the natural way.
