In parallel with the installation of equipment, tests of the plant’s infrastructure, such as piping, have begun. In December, so-called cold (i.e., without heat, gas, or with end-of-life tires) commissioning activities of subsystems will start, which will continue into 2026.

During the project’s engineering phase, Enviro, together with Infiniteria, identified several possible plant changes and process improvements, which, after discussions with Antin and Michelin, have been decided to be implemented already in the Uddevalla factory. These improvements aim to strengthen the industrialization of the plant and further improve efficiency and availability, as well as, among other things, enable more efficient maintenance, safer material handling, and a safer workplace. The reinforcement work will affect the start of the hot commissioning, i.e., pyrolysis of end-of-life tires in pre-production series, which will take place during the first part of 2026.

This, in turn, affects the timeline for when the Provisional Acceptance Certificate is expected to be achieved, which is the final milestone for the project and the point at which the plant is handed over to the operating company Infinitera. PAC has previously been communicated to mid 2026 and will as a consequence be achieved during the second half of 2026.
