Aduro Advances Clean Tech Pilot Plant To Phase 2 Commissioning, Staying On Schedule For 2025 Launch

Aduro Clean Technologies Inc. ("Aduro" or the "Company") (Nasdaq: ADUR) (CSE: ACT) (FSE: 9D5), a clean technology company using the power of chemistry to transform lower value feedstocks, like waste plastics, heavy bitumen, and renewable oils, into resources for the 21st century, today provides an update on the progress of the Next Generation Process (NGP) Pilot Plant.

Highlights of Ongoing Commissioning Progress

• On-schedule progression: The NGP Pilot Plant remains on schedule, having advanced from Phase 1 to Phase 2 commissioning as planned.
• Commissioning of core systems underway: All major modules, including the extruder, Zeton-fabricated process skids, and Siemens automation network, are now installed at the London, Ontario facility and are progressing through staged commissioning.
• System validation milestones achieved: The extruder successfully completed Site Acceptance Testing (SAT); Zeton skids passed Factory Acceptance Testing (FAT); and Siemens is continuing work on automation system commissioning alongside physical equipment.
• Phase 2 commissioning focus: Current activities include sequential testing, subsystem verification, wet runs, and process tuning through November and into mid-December 2025, preparing the plant for integrated operation.
• Operator training and procedures: Commissioning activities also include planned operator training and development of standardized operating procedures, ensuring readiness for continuous plant operation and future scale-up phases.
  
  
  
   

The NGP Pilot Plant is a key step in the Company's scale-up pathway, designed to validate Hydrochemolytic™ Technology in continuous operation, establish operating parameters across target feedstocks, and produce product samples and quality data for customer evaluation. It will confirm mass and energy balances, yields, and controllability, supply data to support environmental assessments and lifecycle analyses, support operator training and procedures, and generate the key data to inform the design basis and integration approach for the previously announced demonstration plant with an initial capacity of 8,000 tons per year.

All three main systems are now onsite at the recently expanded Aduro laboratory facilities in London, Ontario, and commissioning has advanced into its next phase. Since the last project update, the NGP Pilot Plant moved from Phase 1 into Phase 2 commissioning. Phase 1, which began in September 2025, focused on assembly and installation of major systems, mechanical completion, and verification of utilities and communications. During this period, the extruder system was installed, commissioned, and successfully completed its Site Acceptance Test (SAT). The modular process skids fabricated by Zeton Inc. also completed Factory Acceptance Testing (FAT) prior to shipment and have since been delivered to site. Siemens Canada completed configuration of the automation, control, and communication systems, and integrated the extruder systems, utilities, and ancillary systems into an integrated control network. Additional work included connection of plant utilities, electrical systems, and safety interlocks, ensuring full readiness for process commissioning. Assembly and integration activities continue as the plant progresses through Phase 2 commissioning.

The commissioning roadmap continues to follow a structured progression. Phase 2 commissioning, which began in October 2025, focuses on integrated operations, wet runs, and process tuning. These activities will continue through November and into mid-December, after which the Pilot Plant will move toward final preparation for extended operation campaigns.
