Reusing non-potable water from urban wastewater treatment plants in our industrial complexes
Water is an increasingly scarce yet essential resource to continue our production processes, and at Repsol we make an efficient and sustainable use of it. As such, working to reduce water withdrawal and reusing this resource as much as possible is part of our strategy, which demonstrates our commitment to circular economy and the UN Sustainable Development Goals.
With this project, we positively contribute to the United Nations' 2030 Agenda through the following SDGs:
An example of this commitment is the participation of our Tarragona Industrial Complex in a circular economy project aimed at reusing water from urban wastewater plants from Tarragona and Vilaseca. Even though this water is not suitable for human consumption, it's rather suitable for industrial process, particularly in the complex's cooling towers and steam generation boilers.
This project, which has been in operation since 2012, first consists in collecting urban waste water at the discharge point before it reaches the sea. Then, after undergoing a treatment process and demineralization by inverse osmosis membranes, it is distributed to companies that consume it. This way, water withdrawal from the Ebro and Gaià rivers is reduced, resulting in more water available to the communities in the area.
Since we launched this project, we have used 40% of the total water treated, which reduced by 10% the fresh water consumed overall in 2018 and 2019.
Fuels from urban waste
We recover leftover energy from urban waste that has reached the end of its useful life in order to produce fuels.
We obtain new polyolefins from recycled materials, while guaranteeing top quality and functionality.
We bring renewable energy generation to the point of consumption by creating solar communities.
Drilling mud management
We transform drilling mud waste into new fuels by applying thermal desorption techniques.
We transform plastic waste into circular polyolefins that feature the same quality and functionality of virgin materials.
Lubricants formulated with regenerated bases
We use base oils derived from the regeneration of used oils to produce new lubricants.
Waste treatment in exploration and production operations
We apply bioremediation and compost techniques to make use of waste.
Reusing asset equipment
We extend the useful life of our asset equipment by reusing it in our own operations or those of other companies.
