Successfully produced the cheapest biofuel in the world

Tests conducted have shown that biodiesel extracted from the factory's waste cooking oil is safe and complies with all established standards.

Scientists at the Autonomous University of Pueblo, Mexico, have successfully produced biodiesel from waste cooking oil, at the cheapest price in the world, reducing up to 90% compared to current prices and contributing to reducing environmental pollution.

According to a VNA reporter in Mexico, a pilot plant has been built to produce this biodiesel.

The cost of 1 liter of new fuel is only 3 Mexican pesos, while the price on the international market is up to 20 pesos/liter (equivalent to 1 USD).

Experts at the Catalysis and Energy Laboratory of the Mexican Academy of Sciences say this is the only plant in the world that can produce environmentally friendly gas at a super cheap price.

The pilot plant consists of two reactors, the first one is used to feed waste oil to conduct the catalytic reaction and the second one is used to clean and dry the fuel obtained from the first reactor.

Combined with the use of a system of solar panels to heat water and generate electricity for use in the production process, along with the application of a series of control and support mechanisms, creating a safe, economical and sustainable production process.

To find a catalyst to convert waste cooking oil into fuel - a biofuel that has a safer and more economical reaction than any other fuel - scientists had to spend more than 5 years researching, repeating the experimental process many times to be able to create a suitable catalyst.

In addition, to get a low-cost product, the researchers chose waste burnt cooking oil, which can be obtained free of charge from restaurants, hotels or local families, for reuse.

On the other hand, scientists are also researching the use of solar energy to replace electricity in biodiesel production to avoid safety and environmental issues and reduce production costs.

The tests conducted have shown that the biodiesel extracted from the factory's waste cooking oil is safe and meets all the standards set out, and this invention can be considered as a technology transfer project suitable for the current situation, when the world's gas resources are gradually depleted.
