Abstract

The present invention relates to an oil sorbent comprising a matrix of intermingled non-woven polyolefin fibres, shredded polyolefin film and cellulosic fibres. In preferred embodiments, the cellulosic fibres are wood pulp fibres, the polyolefin fibres are polypropylene fibres and the polyolefin film is polyethylene film. The invention also provides a process for the sorption of oil comprising the steps of contacting the oil with a sorbent, said sorbent comprising a matrix of intermingled non-woven polyolefin fibres, shredded polyolefin film and cellulosic fibres. The oil sorbent is useful for recovery of oil, especially hydrocarbon oil, from oil spillages, especially spillages into water.
