ADURO REPORTS NGP PILOT PLANT CAMPAIGN RESULTS, ACHIEVING 86% LIQUID HYDROCARBON YIELD

Aduro Clean Technologies Inc. has provided an update on results from the latest operating campaigns at its next-generation process pilot plant.

Highlights:

• Continuous operation: latest campaign conducted under Aduro's current 24-four operating model, meaning 24-hour operation across a planned four-day campaign window;
• Steady-state performance: steady-state conditions were achieved under typical hydrochemolytic conditions and sustained during the defined operational window, with samples collected at regular intervals;
• Process robustness: steady-state conditions were re-established within approximately two hours after intentional operating changes, providing data on process control response and operator procedures;
• Liquid hydrocarbon recovery: results showed 86-per-cent liquid hydrocarbon recovery over the steady-state window, and 85 per cent of the liquid product consisted of C20-and-below hydrocarbons, a carbon number range typically associated with naphtha cracker feedstocks;
• Product quality analysis: product quality indicators were as expected and comparable with products from batch and R2 experimental campaigns using the same polypropylene recovered from waste plastics;
• Feedstock selection: polypropylene recovered from waste plastics was used as a controlled feedstock to establish a reliable operating baseline under defined hydrochemolytic conditions;
• Next campaign progression: results support planning for longer-duration campaigns using mixed polypropylene and polyethylene feedstocks while also informing design inputs for Aduro's planned first-of-a-kind industrial plant.

Over the past few months, Aduro has conducted a structured series of operating campaigns as it transitions from commissioning to sustained pilot plant operations with the goal of achieving continuous, longer-duration runs. These campaigns have ranged from single-day tests to four-day operating windows, and have progressively evaluated the performance of reactor, feed-handling and product recovery systems and overall operability of the plant under typical process conditions of hydrochemolytic technology. Each campaign has produced practical operating data that have been used to refine start-up, stabilization, product recovery and mass balance, and shutdown procedures; establish operating limit; improve equipment performance; and better integration of the feed-handling, reaction and product recovery sections of the Pilot plant into a unified process.

Central to this work is achieving and holding steady state -- the condition in which the reactor, and the material entering and leaving it, remain stable over time. Sustained steady-state operation is an important measure of process operability because it demonstrates that the feed-handling, reaction, product recovery and process control systems can operate together under various operational conditions.

As part of this normal pilot plant development process, the Aduro team has completed equipment adjustments, troubleshooting, cleaning, targeted repairs and procedural refinements. These activities have been incorporated into successive campaigns to improve functionality, reliability, control and resilience.

Building on prior campaigns, Aduro completed its latest planned operating campaign under its current 24-four operating model, meaning 24-hour operation across a planned four-day campaign window. Excluding start-up and shutdown phases, the run operated continuously for 47 hours using polypropylene recovered from waste plastics as a controlled feedstock. During the run, the feed-handling, reaction and product recovery systems operated together under controlled conditions, wherein the reactor was maintained at target temperature, pressure and recipe for hydrochemolytic conversion.

Within the 47-hour run, steady-state conditions were achieved after approximately 12 hours and maintained for an additional 35 hours. Samples were collected at regular intervals to assess process performance, stability of the process and product quality under representative operating conditions. To further evaluate stability, operating conditions were intentionally changed during the campaign. Steady-state conditions were re-established within approximately two hours, providing data on process robustness, operator response and process control strategy.

Over the steady-state window, the total liquid hydrocarbon recovered represented approximately 86 per cent of the mass of polypropylene fed into the reactor during that period. Of the liquid hydrocarbon recovered, approximately 85 per cent consisted of compounds with carbon numbers of 20 or below, which is the range typically associated with naphtha cracker feedstocks. Chemical analysis of the samples collected during the defined steady-state period demonstrated product quality consistent with prior HCT testing using the same feedstock, including batch testing and R2 continuous flow operation at smaller throughput.

The results provide additional data regarding process performance under integrated pilot plant operation and are being used to refine operating assumptions, evaluate scale-up decisions and inform the design basis for Aduro's planned FOAK plant. They also support the next phase of the pilot plant program, including progression from the current 24-four model toward sustained 24-seven operation and longer-duration campaigns using mixed polypropylene and polyethylene feedstocks.

"The NGP pilot plant is doing what it was designed to do: generate practical operating, yield and product quality data that helps us define the parameters for the next stage of scale-up," said Ofer Vicus, chief executive officer at Aduro. "The latest campaign builds on prior runs and provides additional insight into the way the process operates under steady-state conditions. These results strengthen our confidence in our understanding of how the process operates and are helping us to refine the design basis for our planned FOAK plant and support the engineering planning required for longer-duration campaigns and next-stage scale-up activities."

"The latest campaign represents an important operating milestone for the NGP pilot plant," said David Weizenbach, chief operating officer at Aduro. "It demonstrated the team's ability to move the process through start-up, stabilization, steady-state operation and controlled recovery after deliberate operating changes. Each campaign is generating the practical data needed to refine procedures, improve process control and prepare for longer-duration operation."
