According to the Polish Standards PN-C-96050, the term waste petroleum oils refers to the kerosene or ester oil products which have lost their exploitation value. Polish market annually receives over 300 thousand tons of an assortment of lubricating, gear and spindle oils, part of which is used up in exploitation and the rest is left as waste. The subject of our study was to check the possibility of combined distillation of the waste petroleum oil with a certain amount of fine plastics waste such as: polyethylene, polypropylene, polystyrene or poly(ethylene terephthalate). These polymers undergo thermal decomposition in relatively low temperatures (250 - 400°C), into gas, liquid (mostly) and solid products. The experiment was performed for 5, 10 and 15 wt.% addition of the polymers to the loading. The gas products formed in the process of distillation can be combusted, while the solid waste (coal deposit) is used as fuel in e.g. cement plants.
