Resource Saving and Eco-Friendly Technology for Disposal of Used Railroad Engine Oils

The article deals with the problems of handling used motor oils on the railways of Ukraine. At the moment, this waste is transferred to other enterprises for disposal. But, based on international experience, it is advisable to be regenerated directly at the enterprise where it is formed. The purpose of this work is to develop a modern scheme for oil waste disposal. In this regard, various indicators were investigated, reflecting both the operational suitability of oils and their toxicological parameters. As a result, we proposed a scheme and selected special equipment for handling the used engine oils, which allows to reduce the technogenic load associated with their accumulation, handling and minimization, contributes to the return of oil to the technological process. The calculated value of the conditional environmental effect and the approximate payback period allowed us to draw conclusions about the undoubted environmental and economic effect of implementing the proposed scheme.
