In August 2022, John Dorgan, a professor of chemical engineering and materials science at Michigan State University, stood in front of colleagues at the American Chemical Society’s fall national meeting in Chicago and ate a gummy bear made from a wind turbine blade. The presentation, titled “Composite resins for the circular economy: From wind turbines to gummy bear candy and beyond,” was a conference talk backed by a university press release, not a peer-reviewed journal paper — and it detonated across the science press within days. Scientific American, ScienceDaily and dozens of outlets ran versions of the same story: a Michigan chemist had found a way to dissolve a wind blade and turn part of it into candy.
The premise was sound, even if the “gummy bear” framing made for better headlines than chemistry lessons. Wind blades are built to survive decades of flexing in weather, which means the glass fiber inside them is bonded with a thermoset epoxy — a resin that, once cured, cannot be melted, dissolved or reshaped. That permanence is a design virtue in service and a disposal problem afterward. Dorgan’s team built something structurally similar but chemically different: a resin that could be deliberately taken apart once the blade’s working life ended.
What the original material actually did
The MSU resin combined glass fibers with a plant-derived polymer, polylactide (PLA), dissolved into a synthetic monomer, methyl methacrylate (MMA). Under vacuum, that syrupy mixture impregnated the fibers and then hardened into rigid composite panels — structurally a fiberglass laminate, but chemically a thermoplastic, not a thermoset. The distinction is the entire point: a thermoplastic can be dissolved back into its starting ingredients, while a thermoset cannot.
At end of life, the team’s process used alkaline digestion to break the cured resin apart into separate streams. The glass fibers came out intact, reusable in new composite parts. The polymer fraction split into poly(methyl methacrylate), or PMMA — the acrylic used in vehicle taillights and windows — and poly(methacrylic acid), a superabsorbent polymer used in diaper filling. A portion of the plant-derived component broke down further into potassium lactate, a compound already used as a food preservative and flavoring, which the team formed into the now-famous gummy candy and, separately, into a bathroom sink made of cultured stone. Dorgan ate the gummies himself, on stage, as a demonstration that the material’s end products were genuinely food-safe — a step beyond merely non-toxic.
The research was funded by the David L. and Denise M. Lamp Endowment, which also funds the chair Dorgan holds at MSU. It does not appear to have been published afterward as a peer-reviewed paper — searches of academic databases and Dorgan’s own publication and patent record turn up no journal article matching the wind-blade resin, and his listed patents cover other biorenewable materials — lignin blends, biorenewable polyamides, degradable polymer cascades — rather than this specific glass-fiber/PLA/MMA composite. The 2022 coverage rests entirely on a conference presentation and its accompanying press materials. No citable study followed it.
The caveats were in the room from the start
Dorgan’s own comments at the 2022 meeting undercut the tidier versions of the story that circulated afterward. He told reporters that the bio-based resin could not yet be produced at anything like the volume the wind industry would need — global blade manufacturing runs on a scale that plant-derived PLA supply chains were not built for. He also noted that recovered materials would need to be worth more than it cost to landfill the blade in the first place, an economic threshold that recyclable materials research routinely fails to clear even when the chemistry works. And he raised, half as a joke and half seriously, the question of whether people would actually want to eat candy that had once been part of a turbine blade, regardless of how food-safe the potassium lactate was. Those three qualifications — supply, economics and public appetite — turned out to anticipate most of what happened, and didn’t happen, next.
Searching for what happened after 2022
Four years on, the trail for Dorgan’s specific resin is quiet. There is no follow-up MSU release, no trade-press update, no announced licensing deal, spinout company or pilot installation tied to this material. Searches through 2023, 2024, 2025 and 2026 coverage of wind-blade recycling — including detailed industry roundups — do not mention the MSU project at all. A December 2023 feature in Future Power Technology magazine and a related Power Technology piece on the “circular industry” both cited Dorgan’s approach as one competing idea among several, without reporting any progress beyond the original demonstration. Neither piece, nor anything found since, describes a scale-up, a corporate partner or a timeline.
That absence is itself informative. Academic materials-science demonstrations generate press coverage disproportionate to their development stage — a lab bench result and a shipped product look identical in a headline — and the gap between the two is usually where a story like this one goes quiet without anyone announcing that it failed. The reporting doesn’t say the MSU resin was abandoned, disproven or shelved. It also doesn’t say it advanced past proof-of-concept. The honest state of the record is that a compelling conference demonstration was covered widely, then simply wasn’t followed up on by trade or science press, which is a different and more common outcome than either “commercialized” or “debunked.”
Meanwhile, the industry solved the same problem differently
The wind industry’s blade-waste problem did not wait for MSU’s chemistry. Several companies pursued parallel approaches, and unlike Dorgan’s resin, they have public commercial footprints. Arkema’s ZEBRA project (Zero wastE Blade ReseArch), launched in 2020, completed a 62-meter fully recyclable prototype blade using a different thermoplastic resin system by March 2022 — arriving at a similar chemistry class to Dorgan’s work, but with an actual blade-scale prototype rather than a lab sample.
Siemens Gamesa took a third route: it kept the epoxy thermoset instead of switching to a thermoplastic, developing RecyclableBlade with Aditya Birla Advanced Materials, using an epoxy resin called Recyclamine that contains a hardener designed to be chemically cleaved after service. That blade went into service offshore at RWE’s Kaskasi wind farm in Germany in July 2022 and was extended to onshore projects later that year. By 2025, industry tracking put roughly 100 RecyclableBlade units in operation, with materials supplier Swancor now partnering for larger-scale rollout and its own EzCiclo resin scheduled to begin supplying Siemens Gamesa turbines in 2026.
A fourth approach targets the blades already installed instead of the blades not yet built. Vestas, working with Aarhus University, the Danish Technological Institute, epoxy manufacturer Olin and recycler Stena Recycling under a project called CETEC, announced in February 2023 a chemical process capable of breaking existing, already-cured epoxy blades down into virgin-grade material — useful precisely because it processes the legacy fleet already in the ground or headed for landfill, with no redesign of future blades required. Vestas described the technology as ready for industrialization but still requiring scale-up before wide deployment.
The waste problem the gummy bears were meant to solve is still growing
What has not changed since 2022 is the underlying urgency. Wind capacity additions continue to outpace end-of-life solutions: research firm IDTechEx has projected cumulative global blade waste reaching more than 14 million tons by 2046, with over 117 gigawatts of new wind capacity added in 2024 alone adding to the pipeline of blades that will eventually need disposal. Most decommissioned blades today are still landfilled or mechanically shredded into filler for cement production — a use that recovers some value but destroys the fiber and resin instead of reclaiming either.
Europe has begun forcing the issue instead of waiting for the market to resolve it. WindEurope reports the region generates roughly 20,000 tonnes of blade waste annually already, a figure projected to reach 55,000 tonnes a year by 2030, and the European wind industry adopted a self-imposed ban on landfilling blades that took effect on January 1, 2026. That deadline has done more to concentrate industry attention on the RecyclableBlade and CETEC-style projects — which have installed hardware and named commercial partners — than any renewed interest in MSU’s laboratory demonstration has done for that material.
The gummy-bear framing made the 2022 story unusually memorable. Memorable and consequential turned out to be two different things. The chemistry behind it was real, reviewed carefully enough to survive scrutiny from science journalists who checked with outside experts at the time, and it correctly identified an available reaction pathway from cured composite back to food-grade compound. What it did not have, then or apparently since, was a route past the three obstacles Dorgan named himself: not enough bioplastic supply to match turbine-scale demand, no clear case that recovered material would be worth more than landfill tipping fees, and an open question about whether the public wanted a candy whose backstory involved a turbine blade at all. The idea did not visibly fail. It appears to have simply stayed exactly where it started, while a handful of differently financed approaches — with wind-farm-scale prototypes, named industrial partners and now a regulatory deadline behind them — moved into the gap.
