Washing – The washing process for refined oil utilizes water, salt, caustic soda, sulfur, potassium, acids, and other hazardous chemicals to eliminate impurities. This results in a thick waste similar to tar, which is often repurposed for tire manufacturing. The use of acids in this process can render the oil toxic.
