Abstract
A method is provided for treating 'spills' of materials, e.g. an offshore oil spill, wherein an ungelled mixture of gelatin is deposited onto the material and then allowed to gel. As the gelatin gels, it 'traps' or entrains the material into the gelled mass of gelatin whereby the material can readily be retrieved by merely retrieving the gelled gelatin. The gelling of gelatin is fully reversible in that gelatin will return to its liquid state merely upon reheating, thereby allowing the spilled material to be separated from the gelatin so that the material can be recovered and the gelatin to be reused.
