Traditionally known for its work in the petrochemical, oil & gas, and power sectors, TR is now applying its engineering expertise to support Europe’s climate goals and the decarbonization of industry.
“Técnicas Reunidas is currently developing and executing low-carbon projects across Europe, the Middle East, and the Americas, including flagship initiatives in renewable hydrogen, green ammonia, e-methanol, biofuels, circular economy and carbon capture and storage,” says Bernardo Herrera Rodríguez, Energy Transition Project Manager at Técnicas Reunidas.
A Key Engineering Partner in Plastics2Olefins
In the Plastics2Olefins project, Técnicas Reunidas S.A. plays a vital role in two distinct phases: the Pilot Plant and the Demonstration Plant.
“In the Pilot Plant, our role has been focused on optimizing downstream processes (Work Package 3) by integrating units for gas cleaning and condensation, enhancing the liquid fraction, and valorizing char. This work has been essential for developing the necessary concept and design databases for the Demonstration Plant, explains Herrera.
As the project transitions into the Demonstration Plant phase, Técnicas Reunidas is leading Technical Integration and Engineering (Work Package 5) and conducting solids characterization, which includes both plastics and char — crucial steps for designing the plant’s solid-handling systems.
Progress and Results
Since joining the project, Técnicas Reunidas has made significant progress. They have successfully developed the purification system in the Pilot Plant, as well as the Design Basis Definition and the Conceptual Design Package for the Demonstration Plant.
“Currently, the team is working on the Basic Design Package, which is 66.7% complete and is expected to be finalized by January 2026. Completing this phase will allow us to proceed with the Detailed Engineering, Procurement, Construction, Commissioning, and Start-up of the Demonstration Plant,” notes Herrera.
He can reveal that the results so far are promising:
“The ongoing work in the Pilot Plant has refined processes that enhance the efficiency of gas cleaning and condensation, significantly improving the overall performance of the facility.”
The company’s proactive approach and expertise significantly contribute to the project’s overall success, ensuring timely progress and adherence to its goals.
“By engaging in comprehensive solids characterization and refining engineering strategies, Técnicas Reunidas is positioned to ensure the successful transition from the Pilot Plant to the Demonstration Plant,” says Herrera.
Innovation for a Sustainable Industry
Through its technical excellence and global perspective, Técnicas Reunidas continues to expand its role as a trusted partner in sustainable industrial transformation.
“Innovation and sustainability are central to the company strategy, with a strong focus on research and development to integrate advanced technologies into its projects,” comments Herrera.
In Plastics2Olefins, the company’s contributions demonstrate how advanced engineering can unlock the potential of chemical recycling, bridging the gap between laboratory innovation and industrial application — and turning circular economy ambitions into real-world impact.
