After it is collected, waste plastic will be crushed down and burned at the temperature of 350 degrees centigrade under the condition of oxygen shortage with steam supplement to obtain crude oil. Crude oil will then be treated to obtain petrol and diesel oil.

Dr. Quyen said that 1,000kg of crude oil can be obtained from every 3,000kg of waste plastic. Waste oil is used as fuel during the burning process. This project contributes considerably to environmental protection.
