Used automotive oil filters - An environmental hazard from the Polish perspective

Usually motor oil and used oil filter are exchanged simultaneously. Used motor oil contained in the filter presents a menace to the environment, especially for drinking water. In Poland, used oil (as a hazardous waste) is collected and re-refined, but the program does not include filters collection. In the presented paper, an attempt was made to estimate the quantity of used oil remaining annually in used oil filters. The assessment is based on the data obtained from the experiments and statistic data. Legal solutions and technical means of used oil filters collection in the U.S.A. (where every second used filter is recycled) were analysed. The means for solving the problem in Poland were suggested.
