Due to the decline in soil quality and high volume of soil pollution in Iran, it is necessary to use methods that reduce or eliminate contaminants in the soil in a wide range of Iran. Contaminated soil was also removed from the landfill located in Aradkuh Kahrizak complex. Using thermocouple method, two types of biochar with different characteristics were produced from food waste and oil meal. The standard deviation and mean were calculated using R software and Shapiro-Wilk test was performed using SPSS software version 26 to ensure the normality of the data. Biochar from oil meal and food waste have a significant effect on reducing the amount of heavy metals in the soil and improve the soil. If they do not have a significant effect on improving the physical and chemical properties of soils. The reduction of heavy metals and the increase of soil fertility, in addition to the initial biomass and pyrolysis conditions, also depend on the type of soil granulation.
