Abstract
This disclosure is a method of converting oil and water containing sludge to dry waste in a plurality of steps as follows: 1. Adding to the sludge a petrophylic material to absorb the oil and to separate out the water which is permitted to drain. 2. Adding fibrous material for strength to bond the petrophylic material. 3. Having drained the excess water from the sludge add hydrophylic material to absorb any of the water which may be intermixed. 4. Sealing the external surface of the substantially dry material.
