Waste treatment in Exploration and Production 

Sustainable waste management in our facilities

At Repsol, we are very mindful of waste 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 examples of waste treatment are:

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:

  • Provide nutrients to soils to serve as fertilizer for farming.
  • Restore over-developed areas and carry out revegetation activities.
  • Convert waste into a useful element for us and our surroundings.
  • Icon jugs

    26 tons of compost

    have been generated at our Block 57 facilities in Peru and in Campo Margarita, Bolivia in 2019. This compost has been used as fertilizer for soils in our facilities and in local communities.
  • Icon recycling bin

    More than 70 tons of organic waste

    from cafeterias at our facilities in Bolivia have been donated to nearby livestock farms to be used as animal feed.

Reusing water

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:

  • Reusing domestic water waste for watering green spaces at our facilities in Margarita, Bolivia.
  • Reusing water generated as a consequence of air conditioning condensation in our facilities in Malaysia.
  • Capturing and storing rain water for its use in cleaning at our facilities in Ecuador, as well as for construction projects on roads and pathways in our exploration projects in Bolivia.
  • Reusing the water obtained after purging boilers in the process of preparing drilling mud in our exploration projects in Russia.
  • Classification by key lines and value chain

    Our circular economy projects are aligned with the key lines of our strategy and are present in our entire value chain, from obtaining raw materials to commercializing products and services.
