Aduro Reports 88.8% to 90.8% Condensable Hydrocarbon Yield Across Changing Polyolefin Feeds in 75-Hour NGP Campaign

Aduro's September NGP Pilot Plant campaign achieved condensable hydrocarbon yields of 88.8% for 100% polypropylene, 90.8% for an 80:20 PP/PE blend, and 89.2% for a 50:50 blend over 75 hours processing approximately 758 kg of polymer. The company reported consistent product-quality metrics and reduced the time required to return to target operating conditions by roughly two hours versus a comparable prior run. Pilot data are being supplied to Saipem for Early Works engineering and procurement on Aduro's first-of-a-kind chemical-recycling plant at Chemelot, while future testing will shift toward longer runs with more complex waste-plastic feedstocks.

Analysis

The relevant valuation question for ACT is no longer whether controlled polymer runs can generate liquid output, but whether heterogeneous post-consumer feedstock can run continuously without eroding yield, creating fouling, or requiring uneconomic sorting and pre-treatment. The disclosed tests remain too short and too clean to establish availability, catalyst/consumables intensity, energy use, or a saleable-product netback—the variables that determine whether FOAK economics can support project finance. Accordingly, any near-term equity strength is likely narrative-driven rather than a material de-risking of revenue or cash-flow estimates.

Over the next 1-3 months, the first longer-duration runs on real-world waste streams are the key binary catalyst. A successful result would need disclosure of sustained uptime, mass balance including gas and residues, contaminant tolerance, and product specifications; yield alone is insufficient. Failure to provide these measures, a campaign interruption, or a need for extensive feedstock preparation would likely compress ACT's commercialization multiple and extend its external-financing runway risk.

Saipem's involvement modestly improves engineering credibility but does not yet constitute EPC commitment, performance guarantees, customer offtake, or construction funding. SPM's earnings exposure is immaterial at this stage; its principal upside is strategic optionality if chemical recycling progresses into a repeatable engineering-services funnel, while its larger waste-to-value competitors and established pyrolysis providers retain the advantage in operating history and balance-sheet capacity. The contrarian view is that apparent process-control improvement may be exactly what a pilot should deliver, not evidence that scale-up risk has been retired.

Key Decisions for Investors

• Do not add directional ACT exposure solely on this release; treat it as a watch catalyst until the company reports at least multi-day mixed-waste operation with uptime, contaminant handling, energy intensity, residue disposal and independently specified product quality.
• For existing ACT longs, retain only venture-style sizing through the next campaign and use a 15-20% post-release rally without accompanying economic data to trim; upside requires a credible feedstock/offtake or funded FOAK milestone, while downside is a delayed campaign, weaker yield on contaminated material, or a capital raise.
• Avoid using SPM as a direct read-through long: the engagement presently creates limited earnings sensitivity. Reassess only if Saipem discloses an EPC award, meaningful backlog value, or contractual performance/technology-risk allocation.
• Set alerts for FOAK capex guidance and financing terms. A capex estimate materially above peer chemical-recycling projects, or financing before durable-feedstock data, would be a bearish ACT falsifier because dilution and cost-of-capital would overwhelm pilot progress.
