Christopher Hailstone brings a unique perspective to the circular economy, bridging the gap between industrial energy management and the evolving landscape of resource recovery. As an expert in utilities and electricity delivery, he has spent years navigating the complexities of grid reliability and the security of supply chains that power our modern world. His deep understanding of how large-scale infrastructure projects transition from fossil-fuel reliance to renewable systems makes him a vital voice in the debate over advanced recycling technologies. Today, he helps us unpack the regulatory friction in Colorado and across the United States, where the accounting of recycled materials is no longer just a technicality, but a pivotal battleground for the future of the American manufacturing and waste sectors.
Throughout our discussion, we explore the intricate balance between litigation and collaboration in state-level environmental policy, specifically focusing on the recent legal maneuvers in Colorado. We delve into the technical differences between mass balance allocation methods—such as free allocation versus fuel-excluded models—and how these choices dictate the scalability of multibillion-dollar chemical recycling investments. We also examine the economic pressures facing the recycling industry, the potential impact of state-specific legislation like California’s textile and packaging bills, and the ongoing tension between industry-led standards and federal oversight.
In many states, the choice between litigation and collaborative administrative review has shaped the roadmap for Extended Producer Responsibility (EPR). How do you evaluate the current pathway for approving alternative mass balance methods, and what specific steps must producers take to ensure third-party certifications meet rigorous transparency requirements?
The shift we saw in Colorado, where the American Chemistry Council voluntarily withdrew its lawsuit on February 9th, signifies a move toward a “wait and see” collaborative approach rather than a full-scale legal war. However, it is clear that litigation remains a “just in case” tool for industry players who feel that regulatory agencies are overstepping their authority or showing “inexplicable hostility” toward advanced recycling technologies. For producers, the current pathway is defined by the Circular Action Alliance’s role as the Producer Responsibility Organization, which now has the power to review third-party certifications for alternative mass balance methods. To succeed, producers must move beyond self-regulation and embrace a framework where every unit of recycled content is traceable and verifiable, ensuring that no material diverted for energy recovery is counted as recycled content. This requires a rigorous audit trail that can withstand the scrutiny of a program plan amendment, which is exactly the mechanism the Colorado Department of Public Health and Environment has established for future summer discussions. It’s about building a bridge between the high-level legal complaints filed in November 2025 and the ground-level operational reality of managing thousands of tons of complex packaging waste.
Free allocation allows for flexible credit assignment across product lines, while fuel-excluded methods prevent credits from being applied to energy recovery. What are the operational challenges of transitioning between these specific methodologies, and how do these accounting choices directly impact the scalability of advanced chemical recycling infrastructure?
The transition between these methodologies is not just a bookkeeping exercise; it is an infrastructure challenge that touches the billions of dollars currently being invested by companies like Dow, Eastman, and LyondellBasell. Free allocation offers the highest degree of freedom, allowing a facility to assign recycled credits to any product in its portfolio, which is essential when you’re dealing with the messy, varied outputs of chemical recycling that often include oils and fuels alongside polymers. If a state moves toward a fuel-excluded approach, as we see the European Commission doing, the operational challenge becomes one of precise segregation, where recycled units used for energy are essentially “lost” from the system and cannot be monetized as PCR content. This creates a high-stakes environment where the “proportional” method—which assumes recycled units flow exactly like virgin units—can feel too rigid for the dynamic nature of chemical reactors. Without the flexibility of free allocation, the economic incentive to scale these facilities diminishes, as producers cannot easily prove to their brand-owner customers that the plastic in a specific container is “recycled” in a way that consumers understand and trust.
Market volatility for virgin fossil fuel-based plastics often undermines the economic viability of mechanically recycled materials. How can mass balance accounting help establish a stable price premium for recycled content, and what metrics should companies track to prove this shift actually reduces the overall demand for virgin plastic?
Recycling is, at its core, a business that is currently in significant trouble, particularly when we see the market for mechanically recycled PET bales crashing due to the low cost of virgin fossil fuel-based alternatives. Mass balance accounting acts as an “economic counter” to the direct subsidization of the virgin plastic industry by allowing companies to sell products at a premium even when the physical molecules are difficult to isolate. To make this credible, companies must track the “displacement metric,” which measures how much virgin feedstock was actually avoided at the beginning of the production cycle rather than just focusing on the end-of-pipe output. We also need to see a clear correlation between the adoption of mass balance credits and a measurable decrease in total virgin plastic procurement across a company’s entire multi-state supply chain. If we can’t prove that these accounting maneuvers are ending plastic pollution and reducing our reliance on new fossil fuels, then even the most sophisticated “polymer-to-polymer” systems will fail to win the trust of environmental advocates who view free allocation as a form of greenwashing.
Recent legislative efforts to redefine postconsumer material could exclude credit-based accounting for diverse products like textiles, paper, and glass. How would a move away from technology-neutral definitions complicate the recycling of complex materials like polyester blends, and what specific internal processes are needed to verify physical recycled content?
Moving away from technology-neutral definitions, as proposed in California’s AB 2253 and the textile-focused SB 707, creates a massive hurdle for materials that are notoriously difficult to process, such as a simple polyester-blend shirt. If legislation excludes mass balance or “book-and-claim” accounting, we run the risk of making it legally impossible to claim recycled content for products that literally cannot be recycled through traditional mechanical means. Internal processes would need to shift toward “segregated” or “controlled blending” models, where every batch of post-consumer material is physically tracked through the furnace or reactor, a process that is significantly more expensive than credit-based systems. For glass and paper, which have used forms of mass balance for years, this redefinition could disrupt decades of established supply chain logic, forcing a total overhaul of how “recycled” labels are applied. The industry’s priority is to defend the billions invested in these technologies, but they must do so by proving that their internal verification systems are as transparent as the glass containers they are trying to recycle.
While the European Commission is moving toward a fuel-excluded approach for certain plastics, U.S. federal proposals aim for broader national marketing standards. How does the lack of a unified federal standard in the U.S. affect multi-state supply chains, and what oversight mechanisms are necessary to maintain consumer trust?
The lack of a unified federal standard in the United States creates a fragmented “patchwork” where a bottle sold in Colorado might meet recycled content standards that would be illegal in California or unrecognized in Europe. This creates an enormous logistical burden for multi-state supply chains, as companies must navigate different definitions of “post-consumer material” and varying levels of oversight from state agencies like the CDPHE. Federal proposals like the Recycled Materials Attribution Act aim to solve this, but critics worry they might simply “hand the keys to the castle” to industry-led third-party bodies that lack sufficient government oversight. To maintain consumer trust, we need an oversight mechanism that includes independent, government-verified audits of these third-party certifiers to ensure that claims aren’t just “self-regulation” in disguise. Without a federal baseline that mirrors the rigor of the EU’s Single-Use Plastics Directive, we risk a “race to the bottom” where the threshold for what counts as recycling is set by the most lenient state rather than the most effective technology.
What is your forecast for the future of mass balance accounting in U.S. circularity policy?
I forecast that the U.S. will eventually gravitate toward a “fuel-excluded” mass balance standard, much like the European model, as a necessary compromise between industry flexibility and environmental integrity. While the American Chemistry Council and various state agencies are currently locked in a cycle of litigation and debate, the economic reality of multi-state commerce will force a harmonization of these rules by the end of the decade. We will likely see a move away from “pure” free allocation as consumer advocacy groups and state regulators demand more “physical-link” accounting to prevent greenwashing. The ultimate success of this policy will depend on whether we can build the digital and physical infrastructure to track these molecules with the same precision we use for electricity on the grid. If we can achieve that level of transparency, mass balance will become the gold standard for scaling the circular economy; if not, it will remain a source of legal and regulatory friction for years to come.
