Day 1 Highlights: Technical Progress

Rebeca Yuste (coordinator from REPSOL) and Ángel Martinez (ACTECO) opened the meeting with a warm welcome and overview of the participants’ schedule. Further, the Work Package (WP) and task leads presented the progress on their respective tasks and activities and main achievements within the last period.

WP1 – Project Coordination: Raquel Moreno (ARTTIC) provided an overview of WP1 objectives and tasks, including strategic decision-making, administrative management, and scientific and technical management. Key points of discussion from this WP included the review of changes to the upcoming amendment, and the development of a new data management plan collector and the upcoming interim report.
WP2 – Pyrolysis Optimization: Julio Perez (ACTECO) and Curro Artillo (REPSOL) discussed the identification and supply of pre-treated materials, problems with water content in materials, and the impact of caustic scrubber on pyrolysis gas. They also discussed the potential solutions to the challenges, presented pyrolysis results and also discussed the next steps.
WP3 – Downstream Process Optimisation: Michal Jeremias (VTT) presented an overview of WP3, including tasks related to the revalorisation of heavy tar-like fractions (CIEMAT), purifying gas (VTT), and char characterisation (LHE). Key points of discussion included the impact of water content on chloromethane adsorption and the use of char in cement plants.
WP4 – Digitalisation and Renewable Energies Integration: Prashanth Nadukandi (REPSOL) and Noemi González Cobos (REPSOL) discussed the simulations done about the pyrolysis reactor and development of a planning tool for renewable energy integration including the validation of the tool within Repsol Tech Lab’s facilities.
WP5 – Technical Integration and Engineering: Pablo de Hoyos and Bernardo Herrera (TRSA) provided an overview of WP5 objectives, including design basis, conceptual and basic engineering of the demo plant, and the review of tasks, deliverables, and milestones. They discussed the definition of the feeding system and the start conceptual engineering of the demo plant.
WP7 – Sustainability Assessment and Replicability Potentials: Mikolaj Owsianiak (DTU) presented a brief overview of WP7 progress, including the initiation of tasks related to life cycle assessment (LCA) and the need for data confirmation from technical partners, Cost-benefit analysis and prefeasibility study on replication potential (lead by SIN).
WP8 – Exploitation, Communications, Dissemination & Training: Alemu Belay (SIN) presented an overview of tasks and deliverables achievements. Key points included the status of communication and development of the dissemination materials, the development of learning modules, and the review of KPIs.

Day 2 Highlights: ACTECO’s Facilities Tour

On the second day we had a fruitful visit to ACTECO’s cutting-edge facilities in Almansa and Ibi, where we saw firsthand how they’re transforming plastic waste into valuable materials to be taken to the Repsol plant to go through an innovative pyrolysis process to obtain olefins.

“We saw first-hand waste storage, processes and final products processed in ACTECO’s facilities, which will contribute having a feasible concept and design of the Plastics2Olefins demo plant,” says REPSOL coordinator Rebeca Yuste.

Exciting things ahead as we continue working together to drive sustainability and create a more circular economy!

Plastics2Olefins General Assembly 2024: Advancing Plastic Recycling with 100% Renewable Energy

The Plastics2Olefins project, an EU-funded initiative, held its fifth General Assembly in Madrid, Spain, in June.

This milestone event brought together project partners and experts to assess the project’s progress and discuss the next steps in creating a demonstration plant at Repsol’s Puertollano site.

Designed to recycle unsorted plastic waste into high-value materials, the Plastics2Olefins demonstration plant will be powered exclusively by renewable energy and is set to pioneer a new era in sustainable waste management.

Plastics2Olefins partners ready for next steps

During the fourth General Assembly of the Plastics2Olefins project in Madrid, Spain, the partners discussed the progress of the project and assessed results achieved during the last 18 months.

Plastics2Olefins is a project with a clear vision of circular economy and advancement of recycling technology through optimisation of the upstream processes waste (heterogeneous plastic waste).

The project will develop a novel plastics recycling process based on high temperature pyrolysis. This process reduces the lifecycle GHG emissions by more than 70% compared to existing plastics recycling processes for unsorted plastic waste, and by more than 80% compared to current end-of-life options for these wastes, i.e., incineration.

Pilot visit

As a part of the project milestone and continuous assessment of the project status, Repsol hosted the fourth general assembly of the Plastics2Olefins project, which was held on November 21-22, 2023, at the Repsol facility in Madrid, Spain. All partners gathered to discuss the results achieved in the last 18 months, and each partner shared the status of all activities and visited the installation and engineering work of the pilot plant at Repsol Technology Lab.

The pyrolysis pilot plant started to run in 2023 with the goal of demonstrating the Plastics2Olefins technology, testing different qualities of plastic wastes and optimizing the operating conditions to maximize the production of circular olefins. The pilot aims to be an industrial application of the project on a medium scale. It uses renewable energy and won’t need permanent human supervision. Furthermore, it can be operated economically and already supports the goal achievement of the European Green Deal.

Inspired partners

Currently, the project progressed significantly on the technical installation of pilot, carried out major engineering works and some preliminary tests have been conducted. Partners presented and discussed the status of the project in major activities of all work packages, technical discussions and visited the pilot plant. The pilot is set up completely and several test runs were already performed. More than 24 hours of continuous operation were achieved. During the test runs, several issues were located and resolved.

In general, from the visit, all partners were inspired to contribute for the next steps of the project and put a concrete plan to execute the upcoming project phases.

During 2024, the validation of the technology will be done carrying out long duration trials for the demonstration of the reliability of the integration of the different stages of the technology.

The pilot will be continuously improved according to the results of the Plastics2Olefins project. The consortium is aiming to achieve a fully automated and uninterrupted operation. After that it will start the scaling up of the technology with the engineering activities and phases of the Plastics2Olefins demo plant that will have a capacity of 8000 t/y of plastic wastes.
