Abstract The article describes biological, thermal, chemical, mechanical, biotechnological methods for cleaning the soil from oil waste. Various phytoremediation methods were chosen for cleaning the soil from crude oil. The purpose of the article is to obtain quality soil by cleaning the soil from oil and oily pollutants. It must be ensured that the process is carried out in the most efficient way and at the lowest cost.
