ADURO REPORTS 88.8% TO 90.8% CONDENSABLE HYDROCARBON YIELD ACROSS CHANGING POLYOLEFIN FEEDS IN 75-HOUR NGP CAMPAIGN

Aduro Clean Technologies Inc. has provided an update on continued progress in the operating campaign program at its next-generation process (NGP) pilot plant.

Highlights:

• Repeatability across successive campaigns: Multiple NGP campaigns conducted through July, August and September have demonstrated progressive improvement in NGP process control and operation, while maintaining consistent process and product performance across different feed compositions and operating parameters.
• Mixed polyolefin performance: During the September campaign, condensable hydrocarbon yield was 88.8 per cent with 100 per cent polypropylene (PP), 90.8 per cent with an 80:20 PP/polyethylene (PE) blend and 89.2 per cent with a 50:50 PP/PE blend. Condensable hydrocarbon yield represents the recovered liquid and waxy hydrocarbon product and excludes non-condensed hydrocarbon gases. Results were consistent with the objectives of the campaign.
• Latest campaign: The September campaign ran for 75 hours and processed approximately 758 kilograms of polymer across three controlled polyolefin feed compositions.
• Consistent product quality and improving process control: Product quality indicators remained consistent with prior campaign results and the system returned to target operating conditions approximately two hours sooner than in the comparable prior run following changes in process conditions.
• Iterative engineering: Operating findings are being used to refine equipment, instrumentation, controls and operating procedures, with modifications implemented between campaigns and evaluated in subsequent runs.
• Direct first-of-a-kind (FOAK) integration: NGP operating data continue to be used as part of early works engineering and procurement activities for the FOAK program at Chemelot.
• Next stage: The NGP program is expected to progress to longer campaigns using waste-plastic materials supplied by prospective FOAK feedstock partners, including feedstocks with broader compositional characteristics increasingly representative of those being evaluated for the FOAK plant.

The latest September campaign extended this work over a longer operating period, progressing from the established PP operating reference to progressively higher PE content while maintaining product quality indicators consistent with prior campaign results. Condensable hydrocarbon yield was 88.8 per cent on 100 per cent PP, 90.8 per cent on the 80:20 PP/PE blend and 89.2 per cent on the 50:50 PP/PE blend.

Changes in PP/PE feed composition require timely adjustments to operating parameters. Successive campaigns are defining these relationships while demonstrating the ability to continue operation, maintain process control and restore target operating conditions as feed composition changes. In the latest campaign, the system returned to target conditions approximately two hours sooner than in the comparable prior run, providing a measurable indication of continued improvement in process control and operating procedures.

Controlled PP/PE blends allow Aduro to isolate how changes in feed composition affect process conditions and system response before progressing to more complex waste-plastic feedstocks relevant to chemical recycling in Europe. Future testing is expected to extend across the broader PP/PE composition range, including an 80:20 PE/PP blend.

The NGP pilot plant integrates industrial equipment and process controls at pilot scale. Between campaigns, Aduro reviews operating and analytical data, evaluates equipment and instrumentation performance, and implements engineering and operating improvements identified through testing. Subsequent campaigns are then used to evaluate those changes under operating conditions. This iterative approach allows operating constraints to be identified and addressed at pilot scale while continuing to evaluate Hydrochemolytic technology (HCT) reactor chemistry, product performance and integrated system operation, building practical knowledge relevant to the design and operation of the FOAK plant.

In parallel, Saipem S.p.A. is advancing early works engineering and procurement activities for Aduro's FOAK program at Chemelot. The scope includes review of the process design package, optimization of critical equipment packages, preliminary utility integration and refinement of capital cost estimates. Saipem is already receiving operating data generated through the NGP pilot plant, providing a direct path for pilot plant observations and validated improvements to inform the engineering basis for the FOAK plant.

"Successive NGP campaigns are strengthening our understanding of both the chemistry and the operation of the integrated system," said Ofer Vicus, chief executive officer at Aduro. "As feed composition changes, our operations team continues to develop a deeper understanding of how to adjust process conditions and return the system to target operating conditions while maintaining consistent product performance. The progress we are seeing reflects their work in building practical operating knowledge around a pilot-scale system that integrates industrial equipment and process controls. With Saipem already receiving NGP operating data, those learnings are directly informing development of the engineering basis for the FOAK plant."

The next stage of the NGP program is expected to include longer campaigns using more complex waste-plastic materials, including prospective FOAK feedstocks and selected materials arising through Aduro's customer engagement program. This progression moves testing beyond controlled PP/PE blends and broadens the operating data set across feedstocks relevant to both FOAK development and future application testing.
