Waste management in our facilities
At Repsol, we apply this hierarchy 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. This is done 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 and identify the possibility of treating these soils through an aerobic bioremediation technique that employs compost available at that same location obtained from organic food waste, which ends with the soils being deposited into an approved pit. Since 2019, we have treated more than 500 tonnes of soils.
Creating our own compost and seeking synergies with local communities
The majority of our exploration and production operations in remote areas generate 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 and food. 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.
