Abstract:     

The article focuses on the environmental problem related to waste engine oils. To solve this problem, an environmentally friendly solution to the problem of the waste oil recycling for the purpose of its secondary use is proposed. The article describes the existing methods of the waste engine oil recycling. Adsorption cleaning of engine oil is the process of removing impurities from waste oil using adsorbents. Purification is based on the ability of certain solids (adsorbents) to attract and retain molecules of pollutants from the oil on their surface. Pollutants are adsorbed on the adsorbent surface due to physical and chemical interactions. As part of the study, adsorption purification and analysis of the physico-chemical characteristics of the raw material, waste Castrol 5W-30 engine oil, were carried out. Based on the data obtained, a prototype of purified engine oil was obtained. Then, an assessment of the standard physical and chemical parameters of the purified engine oil was performed. The results of the study may be useful for specialists working in the fields of ecology, oil refining and the automobile industry. Thus, the article represents an in-depth study of the problem of waste engine oils and proposes an effective solution for reducing the negative impact on the environment, which makes it a significant contribution to the field of environmental safety and sustainable development.

Keywords: waste engine oils, ecology, utilization recycling, recycling methods, secondary use, environmental protection
