Abstract
Oil spills on water and land may be contained and cleaned by the process of applying wood chips in direct contact with the spilled oil. The wood chips are selected from the group consisting of air-dried, kiln-dried, hot wax-dried and hot oil-dried wood chips having a water content of less than about 30% by weight. The wood chips will float on water and attract the oil. The wood chips pick up oil at a ratio of about 3:1.
