Apparatus for absorbing liquids from a surface which constitute an environmental problem comprising an expendable pillow, said pillow being the form of a container having at least three discrete pockets side by side, each pocket being only partially filled with an organic granular absorbent material occupying not more than about 50% of the volume of each pocket, said container being made from a non-woven synthetic fiber, said container having high permeability and being coated with a surfactant, said granular material having an absorption capacity in excess of 300% so that it may expand on contact with liquids and fill the pockets, the weight of the pillow before use being less than four pounds, said pockets being delineated by means joining opposite faces of said container, said means including a pair of spaced joints between said opposite faces of said container so that said container can be separated by cutting the container between said joints.
