2064251 9101356 PCTABS00003 Method for cleaning up a first liquid floating on or in a second liquid, the method employing absorbent pellets which, in preferred embodiments, have a particular size, density and configuration. A method for making pellets for cleaing up a first liquid floating on or in a second liquid comprising: processing newsprint paper into a reduced form suitable for introduction into a pelletizing machine; feeding the reduced form newsprint paper to a pelletizing machine which extrudes compressed pellets; and sizing the pellets and shaping them so that, upon introduction of the pellets into a first liquid floating on a second liquid, the pellets maintain their position in the first liquid and absorb some of the first liquid before sinking beneath it or being removed from it. A recovering pellet, preferably a cellulose pellet, for absorbing a liquid and from which the absorbed liquid can then be recovered. A pellet, preferably a cellulose pellet, for absorbing a first liquid floating on or in a second liquid. In the preferred embodiments of the methods utilizing a surfactant, the surfactant assists in sinking the material and it can speed up the sinking. Methods for controlling a first liquid (e.g. oil) floating on or in a second liquid (e.g. water or salt water). A compressed pellet, preferably made from newsprint paper, useful in such methods.
