The main process includes the pyrolysis reactor and the so-called main skid. The main function of the latter is to circulate the gas used in the pyrolysis reactor and extract the oil by condensing the gas. It is in the main process that carbon black, oil, and steel are recovered. The main process is followed by the post-process, which 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 based on the company's leading pyrolysis technology. The plant is being built on behalf of the joint venture company Infiniteria, formed by Enviro together with Antin Infrastructure Partners and Michelin.

The construction of the plant, which has been ongoing for about 1.5 years, is now approaching the point where the majority of the process equipment has been delivered and installed, and the main focus is on 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 expected to be reached in mid-2026. In the first phase, the plant will have an annual capacity to process 34,500 tons of end-of-life tires.

"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 Fredrik Emilson, CEO of Enviro.
