From difficult waste streams to downstream testing and first-of-a-kind engineering, outside organizations are increasingly examining Hydrochemolytic Technology and its ability to efficiently recycle a wide variety of plastic types. The question is whether that interest can translate into commercial-scale performance.
Early-stage clean technologies have an unavoidable credibility problem. The company developing the process usually understands it better than anyone else, but it also has the greatest incentive to believe that it will work. That makes third-party behavior particularly useful for investors.
Instead of relying only on what Aduro Clean Technologies (Nasdaq: ADUR) (TSX: ACT) says about its Hydrochemolytic Technology, or HCT, investors can ask what outside organizations have been willing to do around it. Have they examined the chemistry? Supplied difficult feedstocks? Assigned their engineers? Tested the resulting product? Begun planning the equipment and infrastructure needed at industrial scale?
In Aduro’s case, the answers have increasingly become yes.
That does not mean HCT has been commercially validated. It has not. But the progression of outside engagement from scientific interest and controlled evaluations to real-world feedstock testing, pilot engineering and first-of-a-kind plant planning is becoming harder to dismiss as simple promotional activity.
From Curiosity to Evaluation
One of the more credible outside perspectives came from George Huber, a professor of chemical and biological engineering at the University of Wisconsin–Madison. Speaking with IEEE Spectrum, Huber was appropriately cautious: “I have not seen [Aduro’s] detailed experimental results, but I think the concept is very promising.”
Huber was not claiming to have validated Aduro’s results. He was assessing the underlying concept and explaining why its water-assisted chemistry could offer advantages over conventional plastic pyrolysis. His comments established that technical interest in the process was not confined to Aduro itself.
Shell’s GameChanger program represented the next level of scrutiny. Aduro participated in the multistage project examining pure and mixed plastics, contaminants, additives and continuous-flow operation. The company graduated from the program in December 2025 (starting on page 6), and Shell independently lists Aduro among its GameChanger graduates.
The careful interpretation is that Aduro completed a structured development process with Shell, not that Shell adopted HCT commercially. Still, the distinction between passing through a serious technical program and developing in isolation is meaningful.
The relationship with TotalEnergies followed a similar pattern. What began as a confidential technical evaluation expanded into a disclosed research-and-development collaboration (page 7) focused on increasingly challenging waste-plastic compositions. Aduro’s regulatory disclosures say TotalEnergies has provided financial and in-kind support, including access to refining and petrochemical expertise.
There is no strong public TotalEnergies endorsement of HCT, but there is this post on LinkedIn with TotalEnergies’ Manager Strategic Technological Partnerships Frederic Febvre stating “We are very pleased to have opened this new collaborative path with Aduro. We expect to demonstrate together that we can industrialise their technology.”
Problem Owners Bring Materials
HCT became more interesting when companies with real waste problems begin supplying the materials.
GF Building Flow Solutions is evaluating HCT as a possible pathway for recycling crosslinked polyethylene, better known as PEX. The crosslinked structure that gives PEX its durability also makes it difficult to process through conventional recycling systems. On its own website, GF described Aduro as “leading the industry forward by piloting advanced sustainable recycling processes for PEX and other plastics.”
That is stronger than a generic expression of support. GF has a specific material challenge and is working with Aduro to determine whether HCT can help solve it.
Cleanfarms offers another practical test. Agricultural plastics such as silage film and bale wrap often arrive dirty, contaminated and poorly suited to established recycling systems. Cleanfarms Executive Director Barry Friesen said the organization was encouraged by Aduro’s progress and wanted to learn more about its potential application in agriculture.
Again, the wording is cautious because the outcome remains uncertain. But cautious interest from an organization responsible for managing difficult agricultural waste is exactly the kind of outside signal investors should want to see.
The ECOCE collaboration in Mexico moves HCT directly into post-consumer packaging. ECOCE has helped identify representative flexible and multilayer materials, including bags, wrappers and pouches, and the relationship has advanced from mapping those waste streams to technical testing. Rather than giving Aduro ideal laboratory polymers, ECOCE is helping it evaluate materials that reflect actual Mexican collection conditions.
AstroTurf presents a similarly difficult problem. End-of-life synthetic turf can contain multiple polymers, backing materials, adhesives, rubber, sand and field contamination. AstroTurf Vice President Robert Mitchell described the relationship as an opportunity to assess another pathway for difficult-to-process turf materials.
Across these relationships, the pattern is consistent: outside organizations are not merely commenting on HCT. They are bringing Aduro materials that already resist conventional recycling.
Is the Output Useful?
Converting waste plastic into a liquid is only part of the challenge. The petrochemical industry must also determine whether that liquid can function as a useful feedstock.
In October 2025, Hydrochemolytic Oil produced from mixed plastics was processed through a European pilot-scale steam-cracking facility. Chemical Engineering reported that the oil ran without dilution or additional pretreatment, with stable furnace operation and ethylene and propylene yields comparable with the reference fossil feedstock.
That test asks and answers an important downstream question. If recycled oil requires extensive upgrading before a steam cracker can use it, the additional equipment, energy and operating costs could weaken the commercial case.
There is, however, a limitation: the European organization performing the test has not been publicly identified. Investors can reasonably view it as third-party pilot-scale testing, but not as a named petrochemical company’s endorsement.
Engineering Replaces Chemistry
A few years ago, the central question surrounding Aduro was whether its chemistry deserved investigation. Today, some outside organizations are asking how to automate and construct it.
Siemens supplied automation and digitalization technology for Aduro’s Next Generation Process pilot plant (fully operational since Q1 ‘26) while supporting scale-up planning. Siemens Canada executive Joris Myny has called HCT “a compelling alternative to conventional methods,” with Siemens contributing process-control and automation expertise.
That involvement marked a change in the development conversation. Siemens is not simply assessing whether the chemistry sounds promising. It is helping develop the control architecture needed to operate the process consistently and collect the data required for further scale-up.
The selection of Chemelot Industrial Park in the Netherlands for Aduro’s planned first-of-a-kind (FOAK) industrial plant moves the story another step forward. The initial facility is expected to process approximately 10,000 tonnes annually. Chemelot offers established utilities, petrochemical infrastructure, downstream connectivity and access to companies operating across the polymer value chain.
Chemelot business-development director Frank Schaap said Aduro could strengthen the site’s existing ecosystem and contribute to scalable circular-feedstock routes. Brightlands Chemelot Campus CEO Astrid Boeijen framed the challenge even more directly: helping breakthrough technologies move “from the lab to industrial reality.”
Saipem is now working on that transition. The global engineering contractor is providing preliminary engineering and procurement services while contributing to the industrialization of HCT. Its work covers technical and economic optimization and may lead to later engineering, construction and commissioning phases for the FOAK plant. Saipem’s involvement does not eliminate scale-up risk. It does show that the questions have advanced from chemical feasibility toward equipment, utilities, procurement, capital costs and constructability.
What Remains Unproven
Investors should not confuse a growing circle of sophisticated participants with commercial validation.
HCT has not yet demonstrated reliable, economical operation at industrial scale. The Chemelot plant is a first-of-a-kind facility precisely because those questions remain unanswered. Scaling introduces challenges involving heat and mass transfer, contaminants, materials handling, equipment reliability, continuous operation and product consistency.
Shell is not a disclosed commercial customer. TotalEnergies remains a development collaborator. PepsiCo’s invitation for Aduro to participate in its Sustainability Innovation Hub represents access and interest, not technology selection. Saipem can improve the quality of the engineering effort, but it cannot guarantee that the resulting plant will achieve its performance or economic targets.
Those caveats are central to the investment case, not footnotes. The industry is not saying that Aduro has finished proving HCT. What it increasingly appears to be saying is that the technology deserves serious examination.
The organizations doing that examining now include scientific experts, petrochemical companies, owners of difficult waste streams, an industrial-automation leader, an integrated European chemical site and a major global engineering contractor. Their questions have moved progressively closer to commercialization.
Aduro’s next task is harder: turning that interest into repeatable industrial performance and credible economics. If the Chemelot facility performs as intended, the conversation may eventually shift from whether HCT merits investigation to who wants to deploy it. For now, the evidence supports a more measured conclusion, that the industry is looking increasingly closely, but the definitive test still lies ahead.
