Renewable fuels from waste

At Repsol, we have been manufacturing and marketing renewable fuels for years. To do this, we use various raw materials, like used cooking oils and nut shells. One of their main advantages is the reduction in emissions compared to traditional fuels, since the CO2 released during their use is equal to the CO2 that has been previously removed from the atmosphere by the raw material used for their manufacture. In addition, these fuels can be used in existing combustion engine vehicles and take advantage of existing infrastructure.

Facilities at the Cartagena Industrial Complex

Pioneers in Spain

At our Cartagena Industrial Complex, we have begun operations at the first large-scale production plant for renewable fuels. The Cartagena plant has the capacity to produce 250,000 tonnes per year of these fuels, manufactured from organic waste, prioritizing national and European origin, which will be used as fuel in airplanes, trucks, or cars.

This project relies on the circular economy as a fundamental lever to progress in our commitment to the energy transition and in line with our ambition to achieve net zero emissions by 2050, thus contributing to our strategic objectives in the circular economy.
