which are sometimes compensated by cooking oil recyclers for their used deep fryer oil. Cooking oil recycling also results in less used oil being disposed of in drains‚ which can clog sewage lines due to the build-up of fats. Abstract This investigatory project determines the possibility of purifying used cooking oil using sedimentation method. The activated carbon was also used in the experiment to absorb some dissolved substances in the oil. The purified oil was compared to commercial oil in terms

insecticides and many other harmful chemicals; that is the reason why we decided to focus this investigatory project on creating an eco- friendly cleaning solution. The problem of the modern world is that we have created far too much hazardous chemical since it does the daily chores‚ like that of scrubbing the floor‚ in a faster and easier pace‚ unknowing that this can harm the ozone layer. Our investigatory project aims to create an environment- friendly cleaning solution using citrus peelings and some
