Ecofining Technology Will Transform Waste into Renewable Diesel
Repsol, in partnership with Honeywell, is adopting a groundbreaking approach to the production of renewable fuels. Using Honeywell’s Ecofining technology, Repsol plans to convert approximately 240,000 metric tons of waste and raw materials per year into renewable diesel and other products, significantly contributing to the reduction of the company’s carbon footprint.
The Innovative Ecofining Process
The Honeywell UOP Ecofining process will be implemented at Repsol’s plant in Puertollano, Spain. This technology not only allows for the economical conversion of waste into renewable fuels, but also ensures a high yield in production. Materials such as used cooking oil and animal fats will be the primary sources for this conversion.
Berta Cabello, Director of Renewable Fuels at Repsol, emphasizes the importance of this initiative: “Renewable fuels are a key pillar in our commitment to achieve net zero emissions by 2050, and Honeywell provides us with the Ecofining technology to reach this goal.” This plant will be Repsol’s second facility dedicated solely to the production of 100% renewable fuels, strengthening the company’s leadership in this market in the Iberian Peninsula.

The world has bet on green hydrogen as the fuel of the future, but now faces the side effect: producing 1 kilogram requires about 9 liters of ultrapure water, and the largest projects on the planet are precisely in the driest regions of the Earth, where water is already scarce for people.

Environmental Impact and Commitment to Sustainability
Barry Glickman, Vice President of Honeywell Sustainable Technology Solutions, highlights the positive impact of this technology: “Ecofining technology will enable Repsol to convert waste into renewable fuels and reduce its carbon footprint.” The renewable diesel and SAF (sustainable aviation fuel) produced can significantly reduce greenhouse gas emissions compared to conventional diesel or aviation fuel.
Honeywell, in collaboration with Eni SpA, developed the UOP Ecofining to convert a variety of waste raw materials into renewable diesel and SAF. In addition to Ecofining, Honeywell offers other technologies for the production of renewable fuels, including Ethanol to Jet and the newly announced Honeywell UOP eFining, which utilizes green hydrogen and carbon dioxide.
Honeywell: Commitment to Carbon Neutrality
Honeywell recently reinforced its commitment to sustainability, aiming to achieve carbon neutrality in its operations and facilities by 2035. This commitment is based on the company’s track record of reducing greenhouse gas intensity and its history of innovations aimed at helping customers meet their environmental and social goals. About 60% of Honeywell’s research and development investment in 2022 was directed towards ESG (Environmental, Social, and Governance) focused projects for customers.
This partnership between Repsol and Honeywell symbolizes a significant advancement in the production of renewable fuels, marking an important step towards a more sustainable and environmentally responsible future.
