Aduro Clean Technologies Inc. (NASDAQ:ADUR) is trending Wednesday after the company reported strong condensable hydrocarbon yields across a 75-hour operating campaign at its Next Generation Process pilot plant.

Yield Holds Steady Across Feed Blends

Aduro’s latest campaign extended prior work over a longer operating period, progressing from an established polypropylene operating reference to progressively higher polyethylene content while maintaining product-quality indicators consistent with earlier campaigns. Condensable hydrocarbon yield came in at 88.8% with 100% polypropylene, 90.8% with an 80:20 polypropylene-to-polyethylene blend, and 89.2% with a 50:50 blend.

In the latest run, the system returned to target operating conditions roughly two hours sooner than in a comparable prior campaign, which the company said provides a measurable indication of continued improvement in process control.

Aduro said controlled polypropylene/polyethylene blends allow it 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 a broader composition range, including an 80:20 polyethylene-to-polypropylene blend.

Feeding Into the FOAK Plant

Between campaigns, Aduro reviews operating and analytical data, evaluates equipment and instrumentation performance, and implements engineering improvements that are then tested in subsequent runs. In parallel, Saipem S.p.A. is advancing Early Works engineering and procurement activities for Aduro’s First-of-a-Kind Program at Chemelot, including review of the Process Design Package, optimization of critical equipment packages, and refinement of capital cost estimates. Saipem is already receiving operating data generated through the NGP Pilot Plant, giving pilot-scale observations a direct path into 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, CEO of 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 next stage of the NGP program is expected to include longer campaigns using more complex waste-plastic materials, including prospective FOAK feedstocks and materials sourced through Aduro’s Customer Engagement Program.
