Turn rubber waste into cheap oil

Only through pyrolysis, tires, soles and other types of waste originating from used rubber will become burning oil with the cost of half of FO oil. The project has just been announced by the Center for Building Materials in the South.

Dr. Mai Ngoc Tam, the project owner, said that the idea of ​​developing the project comes from the purpose of finding energy sources with low cost, and solving environmental problems because the above garbage is difficult to decompose.

Garbage brought after treatment to remove dirt such as dirt will be put into the incinerator. After burning, the two main components are gas and liquid oil. The gas will be reused as fuel for the furnace, and condensed oil will give the finished product container.

For every ton of rubber waste, about 280 kg of finished oil will be obtained after the process of pyrolysis.

"When used as fuel in industrial incinerators, this oil gives higher heat than FO oil and is equivalent to DO oil, which is the level of environmental pollution reaching Vietnam standards", Mr. Tam said.

According to the project, with only VND 500 million invested, the process will produce an average of 2 tons of oil per day. Finished product price of each kg of oil (1.1 liters) after adding input materials, operating and labor costs, equivalent to only VND 4,000, half the price of FO oil and 1/3 of the price of DO oil being sold retail market.

However, Dr. Tam said that when this research project is implemented, the biggest difficulty of turning rubber rubbish into liquid fuel is to find enough garbage to produce. Currently, rubber rubbish is mainly sold for export to China with the price per kg of 1,500 VND.

Only in Hanoi and Ho Chi Minh City, there are about 5.3 million motorbikes and 540,000 cars. In which each truck uses from 12 to 18 rubber shells, on average, about 40,000 km of vehicles must replace new ones. Therefore, the source of materials for testing is not difficult.

Currently, the project of burning oil from "Technology for recycling waste rubber for liquid fuel" has been certified by the Center of Quality Measurement Technology 3. In mid-June this project will be reported and approved in Hanoi.
