Enviro announced that the delivery and installation of the five pyrolysis reactors for the Uddevalla tyre recycling plant have been completed, in accordance with the previously communicated schedule.

“With the delivery of the fifth and final reactor, all equipment included in the main process is now in place and fully assembled,” says Fredrik Emilson, CEO of Enviro.

The primary process includes the pyrolysis reactor and the so-called central skid, which circulates the gas used in the pyrolysis reactor and extracts the oil by condensing the gas. Carbon black, oil, and steel are recovered in the primary process, followed by a post-process that handles further separation, refinement, and storage.

Since the end of August, the five reactors have arrived in batches at the site outside Uddevalla, where Enviro is constructing the first full-scale recycling plant on behalf of the joint venture company Infiniteria, formed by Enviro in collaboration with Antin Infrastructure Partners and Michelin.

The construction of the plant, which has been ongoing for approximately 1.5 years, is now approaching the stage where the majority of the process equipment has been delivered and installed, with the main focus shifting to further installation. As previously communicated by the company, the plant is expected to be operational towards the end of this year, and the provisional acceptance certificate (PAC) is anticipated to be achieved in mid-2026. In the first phase, the plant will have an annual capacity to process 34,500 tons of end-of-life tyres.

“Having followed this construction in detail since it first started on a snowy day in February last year, it feels very good to see the five reactors in place. The reactors are the most central part of the entire plant as they are the core of our recycling technology. It is in these that we will recycle valuable carbon black and oil and contribute to a more sustainable and circular society with good profitability,” says Emilson.
