Possibilities of Reducing the Harmful Effects of Engine Oils on the Environment

U ovom radu se analizira utjecaj na okoliš te problematika skladištenja i odlaganja rabljenih motornih ulja. Rabljena motorna ulja su vrlo opasan otpad te su stoga zakonskim mjerama svrstana u posebnu kategoriju otpada koja zahtjeva posebne mjere i radnje kako bi se isti zbrinjavao. Razlog tome je taj što motorna ulja imaju veliki kapacitet za onečišćenje, a spojevi koji se nalaze u rabljenim motornim uljima su kancerogeni te mogu izazvati probleme po stanovništvo ukoliko se neadekvatno zbrinjavaju. Motorna ulja se razlikuju po načinu proizvodnje, a glavna podjela je na mineralna, polusintetička ili sintetička motorna ulja. Ovo su tri glavne vrste motornih ulja, a svaka od ove tri glavne vrste ima svoje podvrste. Budući da se motorna ulja troše tijekom uporabe, potrebno ih je mijenjati, a njihovo odlaganje i skladištenje je potrebno provoditi po strogo propisanim procedurama budući da je riječ o opasnom otpadu. Budući da rabljena motorna ulja mogu izazvati velika zagađenja, intenzivno se diljem svijeta radi na načinima kako osigurati da se svaka kap iskorištenog motornog ulja reciklira i preradi, a osim oporabe motornog ulja, radi se i na tome da se smanji negativan utjecaj motornih ulja na okoliš.This thesis analyzes environmental impacts and the problem of storage and disposal of used motor oils. Used motor oils are hazardous waste and therefore, legally, they are classified in a special category of waste that requires special measures and actions to dispose it. The reason for this is that motor oils have a large capacity for pollution, and the compounds found in used motor oils are carcinogenic and can cause problems for the population if they are not adequately disposed of. Motor oils differ according to the method of production, and the main classification of oils is into mineral, semi-synthetic or synthetic motor oils. These are the three main types of motor oils, and each of these three main types has its own sub-types. Since motor oils are consumed during use, they need to be changed, and their disposal and storage must be carried out according to strictly prescribed procedures, since it is a matter of hazardous waste. Since used motor oils can cause significant pollution, intensive work is being done all over the world on ways to ensure that every drop of used motor oil is recycled and processed, and in addition to the recovery of motor oil, work is also being done to reduce the negative impact of motor oils on the environment
