Waste management in our facilities
Waste management hierarchy in our operations
At Repsol, we are very mindful of this hierarchy, and we apply it in our waste treatment: we prioritize minimization, followed by reuse, recycling, recovery - including energy recovery, and as a last resort, safe disposal.
We carefully analyze and classify all the waste we generate in order to optimize its use within our production processes, attempting to "close the circle" by reusing it as raw material.
When possible, we try to apply treatments for waste management in the same location of operation, therefore avoiding the environmental impact of its transportation from the place where it is produced to the location for treatment or final disposal.
We also explore symbiotic alternatives along with local communities that may use our waste as raw materials, for example as fertilizers and feed for animal farms.
Some of our projects
Soil bioremediation in Peru
The project is noteworthy for its pursuit of more environmentally-friendly alternatives, like the possibility of treating soils that may contain hydrocarbons in a remote area through a process called on-site bioremediation, instead of traditional treatment with the help of third parties, which would require the long-distance transportation of the waste. At the facilities, we analyze the possibility of treating these soils through an aerobic bioremediation technique that employs compost, which is obtained from organic food waste produced at the same location.
In 2019, we treated close to 500 tons of soils through this technique, which is then deposited into an approved pit.
Creating our own compost and seeking synergies with local communities
The majority of our exploration and production operations in remote areas generates a certain amount of organic waste that we convert into new resources for our activities or for the local community's use.
Composting improves the treatment of organic waste, which consists of a modification in the final disposal of organic waste that is derived from cooking. Through this, we are able to:
In our exploration and production activities, we reuse water in many of our processes. With the aim of reducing our dependence on fresh water, we seek alternatives like:
Classification by key lines and value chain
Our circular economy projects are aligned with the key lines of our strategy and are present throughout our entire value chain, from obtaining raw materials to commercializing products and services.

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.
We implement solutions to transform biomass into advanced biofuels with low CO2 emissions.
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.
Reusing asset equipment
We extend the useful life of our asset equipment by reusing it in our own operations or those of other companies.
Reusing water from urban wastewater plants
We reuse water from urban wastewater treatment plants to reduce the amount of fresh water consumed.
