Paraná Teenagers Could Transform Cooking Oil into Sustainable and Economic Fuel. A Bus That Used the Fuel Managed to Run for Over a Week.

A project by teenagers transformed traditional cooking oil into biodiesel in Paraná. The group of students who transformed cooking oil into fuel is from Colégio Estadual Conselheiro Carrão, a public full-time high school in Assaí (PR). With this, the teenagers from Paraná created a junior startup for biodiesel generation.

Through the teenagers’ project, a bus ran for almost a week without needing to be refueled. The oil used was not pure; however, it was transformed into biofuel by a group of girls from a public school located in Assaí, almost 400 km from the capital, Curitiba.

The project is led by Eduarda Priscila Miura, 17, Leticia Ayumi Tazima Sato, 17, Luiza Alves de Souza, 17, Eduarda Pietra Santos Paixão, 16, and Fabiane Hikari Kikuti, also 16.

Paraná Teenagers Speak About the Project

The BIOSUN was created for a hackathon, a municipal programming marathon, and developed during extracurricular activities in the full-time high school. Through a partnership with UFPR (Federal University of Paraná), the project to transform cooking oil into fuel had access to the chemistry lab and the necessary reagents from the institution to create biodiesel.

Leticia Ayumi emphasizes that she enjoys the area of natural sciences, the laboratory experience, and the idea of working on scientific research to solve everyday problems. For Eduarda Pietra, this is an opportunity to put into practice concepts learned in class. She highlights that it has been an incredible experience, especially since she has always been curious about the laboratory aspect and grew up hearing a lot about the importance of sustainable ideas.

The Process of Transforming Cooking Oil into Fuel

The teenagers’ project in Paraná is based on the premise that cooking oil, for the most part, is recycled into soap. However, when combined with certain chemicals, it is possible to generate an alternative, eco-friendly fuel with lower pollution levels.

In BIOSUN, the collected waste is heated and combined with alcohol and a strong base. The first batches were generated at the school, and the others were developed within UFPR, at the Jandaia do Sul campus.

Rossi explains that initially, a sample collection was carried out, a small amount sufficient for the bus to participate in the parade. During this phase, the equivalent of 12 liters of oil was collected from the college’s teachers, which were transformed into 10 liters of biodiesel.

The transformation of cooking oil into fuel occurred through a process known as transesterification. First, the oil was filtered to remove any solid residues. Then, the oil was heated and mixed with alcohol and a strong base, generating biodiesel and glycerol, going through 4 washing stages before utilization.

The oldest tree in the world, alive since before the birth of Jesus Christ, is cut down in a scientific study and the case changes environmental preservation rules.

Seen from space, an image taken by an astronaut shows an unlikely oasis in the Saudi Arabian desert, protected by a terrain that slows the advance of sand, surrounded by green circles, remnants of an extinct lake and nearly 10,000 years of preserved history.

An entire island in the Pacific wants to surround itself with a colossal barrier against the ocean to try to escape increasingly violent waves and not be swallowed by the sea in the coming decades.

After ten days orbiting the Moon, science confirms that the astronauts of the Artemis II mission return with altered bodies.

With 7.4 trillion tons of artificial snow pumped in 10 years, an extreme operation could stabilize the West Antarctic ice sheet and prevent a sea level rise of more than 3 meters, but it would require snow cannons, ocean water, and energy on an almost industrial scale at the end of the world.

Peru built a tunnel at an altitude of 4,738 meters cutting through the Andes Mountains, and the road leading to it reaches 4,818 meters, making it the highest paved road in the entire world.

Xiaomi launches new refrigerator with HyperOS system of 508 liters that promises to eliminate 99.9999% of viruses in 120 seconds and keep food fresh for up to 7 days; meet the Mijia Pro.

Without radar, without fines, and without physical barriers: a red road in India uses smart asphalt with different colors and textures to reduce vehicle speed and protect wildlife in a natural and efficient way.

With 5.6 trillion tons of natural hydrogen beneath the Earth, 26 times the known oil and more energy than all the natural gas in the world, the new gold rush is already mobilizing Bill Gates, Amazon, and Petrobras.

War in the Middle East is making Brazil richer: the country has returned to the IMF’s global top 10 thanks to the rise in oil prices, and the projection is to surpass Russia by 2027 and Italy by 2028.

Thousands of small fish were caught climbing a 15-meter vertical waterfall in the Congo using microscopic hooks on their fins in a nearly 10-hour journey that defies gravity.

U.S. researchers publish the first national map of natural hydrogen, placing 30 states on the radar and changing what was known about clean energy in the American underground.

Solar-powered ice factory in the Amazon that eliminated a 5-hour trip to Manaus, prevents the loss of up to two-thirds of the fish, and now ensures income for more than 30 riverside families.

Every time a river flows into the sea, an amount of energy equivalent to a 120-meter waterfall is silently wasted, but Japan has just inaugurated the world’s first power plant that captures this waste and transforms it into electricity 24 hours a day without sun, wind, or fuel.
