About Aduro Clean Technologies

OTC

ACTHF represents an interest in Aduro Clean Technologies Inc., a clean technology company that focuses on using chemistry to convert low‑value hydrocarbon feedstocks into higher‑value resources. According to company disclosures, Aduro develops patented water‑based technologies designed to chemically recycle waste plastics, convert heavy crude and bitumen into lighter oil, and transform renewable oils into higher‑value fuels or renewable chemicals. Its core platform, known as Hydrochemolytic™ Technology (HCT), uses water as a critical agent in a chemistry process that operates at relatively low temperatures and cost to turn lower‑value materials into resources for the 21st century.

Aduro states that Hydrochemolytic™ Technology is intended to process mixed and contaminated waste plastics, heavy bitumen, and renewable oils. In plastics applications, HCT is described as a chemistry platform that can break down large hydrocarbon molecules into smaller liquid hydrocarbons suitable for further upgrading and potential use as petrochemical feedstocks, including in steam crackers. The company has reported pilot‑scale steam‑cracking trials in Europe in which plastic‑derived Hydrochemolytic™ oil produced from mixed waste plastics was processed "as produced," without hydrotreatment or dilution, while achieving stable furnace operation and ethylene and propylene yields comparable to conventional fossil‑based steam‑cracker feedstocks.

Business focus and technology platform

Based on its public communications, Aduro positions itself as a developer of chemical process technologies rather than a traditional mining or extraction operator. Its work centers on:

  • Chemical recycling of waste plastics using Hydrochemolytic™ Technology to produce liquid hydrocarbons from mixed and contaminated plastic waste streams, including flexible and multilayer packaging.
  • Upgrading heavy crude and bitumen into lighter, more valuable oil using water‑based chemistry.
  • Transforming renewable oils into higher‑value fuels or renewable chemicals.

The company repeatedly emphasizes that HCT operates at moderate temperatures with catalysts and relies on water as a central process agent. Aduro describes this as a way to convert low‑value feedstocks into more useful products while aiming for lower process complexity compared with conventional thermal approaches that often require extensive pre‑treatment or hydrotreatment.

Scale‑up pathway: Pilot and demonstration plants

Aduro outlines a structured scale‑up program for Hydrochemolytic™ Technology. A key element is its Next Generation Process (NGP) Pilot Plant, located at its facilities in London, Ontario. The NGP Pilot Plant is designed to validate HCT in continuous operation, confirm mass and energy balances, establish operating parameters across target feedstocks, and generate product samples and quality data for customer evaluation. The company reports that the plant integrates an extruder system, modular process skids fabricated by Zeton Inc., and automation and control systems provided by Siemens, and has progressed through phased commissioning activities including mechanical verification, control integration, safety validation, wet runs, and process tuning.

Beyond the pilot scale, Aduro is working on a Demonstration Plant program. It has described a global site‑selection process and disclosed a non‑binding letter of intent for a brownfield industrial site in the Netherlands being evaluated as a potential location for a demonstration‑scale facility. The company indicates that the demonstration plant is intended as the next step after the NGP Pilot Plant, with engineering trials and early design work focused on long‑lead equipment such as extrusion systems and on integration of pretreatment and Hydrochemolytic™ processing for real‑world contaminated waste plastics.

Collaborations and validation activities

Aduro reports multiple collaborations and external validation efforts related to Hydrochemolytic™ Technology:

  • Shell GameChanger program: The company states it has graduated from Shell’s GameChanger program, a multi‑year collaboration under Shell’s Chemical Decarbonisation initiative. Within this program, Aduro conducted technical evaluations of HCT, including selectivity toward steam‑crackable hydrocarbons, suppression of olefin formation, and tolerance to contaminants such as PET, polyamides, and PVC. Under tested conditions, the process reportedly yielded over 80 percent liquid hydrocarbons with lower gas and char formation, and the program provided external validation of process‑design assumptions and scale‑up pathways.
  • Pilot‑scale steam‑cracking trials: Aduro has announced pilot‑scale steam‑cracking trials of plastic‑derived Hydrochemolytic™ oil at an established pilot facility in Europe operated by a global organization involved in large‑scale petrochemical steam‑cracking technologies. The company reports that its oil, produced from mixed waste plastics, was processed without dilution or further pre‑treatment and delivered ethylene and propylene yields comparable to conventional fossil feedstocks, with stable furnace operation.
  • Engineering trials with KraussMaffei and CHILL: Aduro is conducting industrial‑scale extrusion trials with KraussMaffei Extrusion GmbH and applied research programs with CHILL B.V. at the Brightlands Chemelot Campus in the Netherlands. These activities are intended to evaluate extrusion‑based feed preparation for contaminated waste plastics, understand process variables in the presence of contaminants, and inform the design and integration of pretreatment systems for the Demonstration Plant.
  • Collaboration with ECOCE in Mexico: The company has entered into a multi‑year framework collaboration agreement with ECOCE, a non‑profit environmental association in Mexico that administers a national private packaging management program. Under this collaboration, Aduro and ECOCE plan to evaluate HCT as a potential chemical recycling route for flexible and mixed plastic packaging in Mexico, using real post‑consumer materials sourced through ECOCE’s systems.

Capital markets and listings

Aduro Clean Technologies is identified in recent news as trading on multiple exchanges under different symbols: Nasdaq: ADUR, CSE: ACT, and FSE: 9D5. The ACTHF symbol corresponds to an over‑the‑counter representation linked to these listings. The company has disclosed an underwritten U.S. public offering of common shares and accompanying warrants, with stated plans to direct net proceeds primarily toward construction of its Demonstration‑Scale Plant, as well as research and development, general corporate purposes, and working capital.

Revenue and customer engagement programs

In its financial updates, Aduro explains that its current revenue is earned through the completion of services under Customer Engagement Programs for evaluation of the company’s technology and collaboration work. This revenue is described as non‑recurring and varying with the timing and scope of evaluation projects. The company notes that quarter‑over‑quarter differences in revenue reflect how resources are allocated between scale‑up activities, technical analysis, and customer evaluation programs.

Industry positioning and applications

Across its public statements, Aduro presents Hydrochemolytic™ Technology as a chemistry platform aimed at enabling chemical recycling and upgrading of hydrocarbon streams. In plastics, the company focuses on mixed and contaminated waste streams, including flexible and multilayer packaging that often do not fit existing mechanical recycling systems. HCT is described as operating at moderate temperatures with catalysts to produce liquid hydrocarbons that can be further upgraded or potentially used as feedstocks for petrochemical processes such as steam cracking.

For heavy crude and bitumen, Aduro indicates that its water‑based technologies are designed to convert these heavier feedstocks into lighter, more valuable oil. For renewable oils, the company’s disclosures state that its processes target conversion into higher‑value fuels or renewable chemicals. In all cases, the central theme is the use of water‑assisted chemistry to transform lower‑value feedstocks into products that can integrate with existing industrial and petrochemical infrastructure.

Investor‑oriented considerations

From an investor perspective, ACTHF provides exposure to a company that is developing and scaling proprietary chemical process technology rather than operating large‑scale production assets at commercial capacity. Aduro’s public communications emphasize milestones such as pilot‑plant commissioning, demonstration‑plant planning, external validation programs, and collaboration agreements with industry partners and organizations across North America, Europe, and Mexico.

Because Aduro’s business is in a development and scale‑up phase, many of its disclosures focus on technology validation, engineering progress, and capital raising activities. Prospective investors typically review the company’s filings on SEDAR+ and EDGAR, as well as its press releases, to understand the status of the NGP Pilot Plant, the Demonstration Plant program, collaboration outcomes, and the evolution of Customer Engagement Programs that generate evaluation‑related revenue.
