Renewable fuels from waste
Renewable fuels from waste
At Repsol, we have been manufacturing and marketing fuels of 100% renewable origin 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 conventional 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.
At our Cartagena Industrial Complex, we have begun operations at the first large-scale production plant for fuels of 100% renewable origin. 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.
