Claims
- 1. A method for removing oil or other petroleum-based products contaminating a body of water, comprising dispersing over the contaminated water an amount of an absorbent material sufficient to substantially absorb the oil or petroleum-based products therefrom, said absorbent material comprising the fibrous product obtained by subjecting a moisture-containing fibrous starting material, consisting essentially of a member selected from the group consisting of sulphite reject from a paper mill process, and a combination of sulfite reject and sulphate reject from a paper mill process, to rapid forced heating at temperatures effective to gasify moisture in said starting material and to cause said starting material to expand or burst.
- 2. The method according to claim 1 wherein said starting material is sulphite reject from a paper mill process.
- 3. A method according to claim 2 wherein said sulphite reject consists predominantly of the fine fraction of sulphite reject obtained from a paper mill process.
- 4. A method according to claim 1 wherein said starting material is a combination of sulfite reject and sulphate reject from a paper mill process.
- 5. A method according to claim 1 wherein the temperature of said rapid forced heating is in the range of from about 300.degree. C. to about 1000.degree. C.
- 6. The method according to claim 1 wherein said fibrous product resulting from said rapid forced heating is thereafter treated to apply a thin coat of wax thereon.
