Abstract
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.

Claim 1
Independent Claim
97 words
A method for containment and collection of oil on a surface comprising the steps of: (a) placing wood chips in contact with oil on said surface, said wood chips being selected from the group consisting of hot-oil dried wood chips having a water content of less than about 30% and an oil content of between about 1 to about 25% by weight, and hot-wax dried wood chips having a water content of less than about 20% and a wax content between about 1 and 25% by weight; and (b) allowing said wood chips to pickup said oil.
Claim 2
Independent Claim
97 words
A method for containment and collection of oil on a surface comprising the steps of: (a) placing wood chips in contact with oil on said surface, said wood chips being selected from the group consisting of hot-oil dried wood chips having a water content of less than about 30% and an oil content of between about 1 to about 25% by weight, and hot-wax dried wood chips having a water content of less than about 20% and a wax content between about 1 and 25% by weight; and (b) allowing said wood chips to pickup said oil.
Claim 3
Dependent Claim
25 words
The method of claim 1 further including the step of collecting the now oil-saturated wood chips from the surface which had been coated with oil.
Claim 4
Dependent Claim

Claim 7
Independent Claim
49 words
A method for cleaning an oil spill comprising the step of: (a) placing wood chips in contact with spilled oil, said wood chips having been previously dried in hot oil to a water content of less than about 20% and an oil content of between about 10%-25% by weight.
