Low carbon and circular economy

We explore new raw materials and technological routes that promote circularity

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

What do we focus on?

Industrial transformation

We are working to convert our seven industrial complexes into circular multi-energy hubs, modifying processes to produce materials and products with a low carbon footprint.

Circular economy

We convert waste raw materials into value-added products that we can use at 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.SI Project, a pioneering technology for direct air capture

On the journey of our commitment to reduce emissions, aligned with the Paris Agreement, Repsol Sinopec Brazil has invested in DACMa, a Hamburg-based startup that develops Direct Air Capture (DAC) technologies. The project will pursue the following goals:

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

Develop new adsorbent materials for CO₂ direct air capture.

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

Seek marketing of DAC technology by 2030.

CirQlar, overcoming technological barriers in heat recovery

Implemented at the A Coruña industrial complex, this project will recover low-temperature waste heat (100ºC) and raise it to 150ºC by means of a high-temperature heat pump, reducing greenhouse gas emissions by avoiding natural gas combustion. CIRQLAR will promote more efficient and competitive industrial production, reducing external energy dependence and CO₂ emissions.

24,000 MWh/year of low-temperature heat recovered.

60,000 tCO₂reduced in the first 10 years of operation.

April 2025 is the planned start-up date.
