Low carbon and circular economy

We explore raw materials that promote circularity

What do we focus on?

Renewable fuels produced from waste, circular materials, renewable hydrogen, or CO₂ capture and utilization, as drivers to transform industry and reduce the carbon footprint.

Industrial transformation

We are working to convert our industrial complexes into circular multi-energy hubs, modifying processes to produce low-carbon products.

Circular economy technology

We convert waste raw materials into value-added products that we can use in our industrial complexes, such as biogas or biomethane.

Circular products

We focus on recyclable materials and recycled raw materials that result in more efficient and sustainable high-quality products.

The transformation of the industry, with a focus on the circular economy and carbon management technologies, is key to advancing on the path we have set for ourselves to become a net zero emissions company by 2050.

Technologies to transform the industry and take advantage of the resources

Renewable hydrogen

We are committed to this energy vector with net zero CO₂ emissions for use in industry and as a raw material to produce renewable fuels.

CO₂ capture, use, and storage

Technologies to capture and reduce CO₂ from the atmosphere. They allow it to be transported and stored permanently and safely in the subsoil or to be used to produce synthetic fuels.

Water management

We work on solutions to reduce raw water abstraction by industry and recover water used in industrial processes to avoid spills.

We also focus on…

Circular materials

We design recyclable materials, which also incorporate part of the recycled product in their composition, and will be reused to give them a second life.

Waste technology

We analyze technologies to convert different types of waste, such as municipal solid waste, plastics, or biomass into advanced biofuels and circular materials.

Biotechnology

We use enzymes and microorganisms to develop new materials and processes applicable to the energy industry, such as chemical products or renewable fuels.

Industrial heat recovery

We use waste heat recovery techniques derived from the high temperatures reached in industrial processes to reuse them and thus reduce energy costs.

Geothermal

We investigate this renewable and inexhaustible energy, which is obtained by harnessing the heat of the Earth's interior, stored in rocks, soils, and groundwater.

Success stories

DAC Project, a pioneering technology for direct air capture

On the journey of our commitment to reduce emissions, Repsol Corporate Venturing invested in DACMA in 2023. It is a startup that develops Direct Air Capture (DAC) technology based on solid adsorbent. Alongside this investment, a project was contracted by Repsol Sinopec Brasil to DACMA to install a 300-tonne CO₂ plant, which was launched in October 2024. The following goals are:

Start the operation of a plant with a capacity to capture 300 tonnes of CO₂/year.

Develop new adsorbent materials to capture CO₂ from the air.

Analyze the effects of CO₂ injection and mineralization in basaltic rocks, through R&D projects.

Seek marketing of DAC technology by 2030.

We promote technological innovation for SAF development

We coordinate the "Madrid Vuela Sostenible" (Madrid Flies Sustainable) project, with the support of the Community of Madrid and the European Union, to advance in the decarbonization of air transport. Together with IMDEA Energía, ARIEMA, and EVOENZYME, we are promoting the generation and dissemination of knowledge on technologies related to decarbonization and the circular economy, facilitating the transformation of waste into sustainable aviation fuels.
