It does not matter to what phase of industry one turns, a certain amount of oil is possible of reclamation from the waste employed in connection with the conduct of the work. The volume recoverable naturally varies widely according to the nature of the trade pursued, and in some instances the individual yield may appear to be insignificant. But, during the course of the year, even in a small shop, the figure is certain to become impressive and well worth the efforts expended, as well as the money invested in the requisite plant, while, if the one instance be multiplied by the number of other similar establishments distributed throughout the country, the aggregate must necessarily be formidable. The table opposite furnishes a few actual results in the selection of industries specified. It will be observed that the yield varies widely according to the industry concerned, but in every instance it will be observed that the figure is such as to render the process profitable, not only on account of the oil thus procured, but from the release of the waste or other absorbent for a further spell of useful service. If the waste, or other material, has been employed only for wiping parts, or mopping up free oil, passage through the oil separator will suffice, but if it has been utilized for general work and has become badly soiled, it requires washing. The sludge resulting from this process is subsequently passed through the oil-recovery plant instead of being thrown away, the reclamation thus being complete, while the rags or other textiles are passed through cabinets or other suitable facilities to be dried quickly.
