Advanced biofuels from waste

At Repsol, we have been manufacturing and marketing biofuels for years. To do this, we use various raw materials, like vegetable oil waste, used cooking oil, biomass, and wine-based alcohols from waste in the wine industry. The use of these raw materials allows us to significantly reduce CO2 emissions compared to the traditional fuels they replace. Used cooking oil, for example, reduces emissions by 85-90%.

Cartagena Industrial Facility

Pioneers in Spain

At Repsol, we are building the first low-emissions advanced biofuels plant in Spain at our refinery in Cartagena. The plant will produce biofuels from recycled raw materials and have an annual production capacity of 250,000 tonnes of hydrobiodiesel, biojet, bionaphtha, and biopropane to be used in aircraft, trucks, or cars.

This pioneering facility will be equipped with cutting-edge technology and the most efficient solutions and will include the commissioning of a hydrogen plant that will fuel a new hydrotreatment unit.

Strategic objectives

Relying on the circular economy as a tool to efficiently use resrouces, these are the objectives related with this project which are outlined in our commitment with energy transition and are in line with our aim of becoming net zero emissions by 2050

Biofuel from waste for aircraft 

We've successfully completed the first batch of aviation biojet fuel from waste on the Spanish market at our Petronor industrial facility. This important milestone in low-emissions fuel production represents an evolution in the decarbonization of air transport, a sector where electrification is not viable at the moment.

The batch consists of 5,300 tonnes of fuel that meets strict product quality requirements and sustainability conditions throughout the chain of production, logistics, and marketing. Its use will avoid the release of 300 tonnes of CO2 into the atmosphere – equivalent to the CO2 released by 40 Madrid-Bilbao flights.
