Characterization of new oil filters revealed that it may be necessary to treat heavy-duty used oil filter scrap differently than light-duty used oil filter scrap as the difference in content and variation between the two is quite dramatic. The crushing and draining of LD filter may provide an adequate scrap for steelmakers, but the HD filters will probably require additional processing such as shredding, pyrolysis, etc. Many problems and concerns exist with both UOF scrap users and UOF processors. Some of these problems have already been adressed with better scrap from larger chrushers, shredders and burning techniques. The remaining concerns must be adressed if the current rate of recycling is to be increased. Increased crushing force and the introduction of multiaxial crushing provide a scrap product that is much different than the 'pucks' of yesterday. Steelmakers must realize that technology has changed the types of scrap available. The results of surveys of both ferrous scrap users and used oil filter processors reveals that the current recycling rate is at least 15 % of the estimated 425 million filters dispose of annually in the United States. Further investigation of this topic is warranted due to the potential recovery of a high quality steel scrap commodity and recyclable oil while preventing potential enviromental problems.
