Resource Abundance Weekly Review 2026-07-02

Week In Review

The past week’s resource abundance news kept returning to a single theme: how much of the industrial base we can rebuild without touching the mine face. Cornell’s Direct Electrode-to-Electrode Regeneration (DEER) process proposes reviving spent lithium-ion cells in an electrochemical bath rather than shredding and smelting them, aiming to cut recycled-cell manufacturing cost by more than half. In parallel, Stegra closed a $1.6 billion financing round for its hydrogen-based steel plant in northern Sweden — the largest single check written for a green-steel first-mover. And QuantumScape and Honda formalised a joint R&D agreement that focuses as much on manufacturing process as on cell chemistry, signalling that the solid-state battery race is now about factories rather than lab records.

A second thread ran through separations and clean water. A multi-institution team led from CSIR-CSMCRI in India engineered polyoxometalate-cluster membranes with perfectly uniform one-nanometre pores, promising precision filtration for pharmaceuticals, textiles and drinking-water treatment. Aarhus University researchers separately showed that intense UV light can generate hydrogen radicals in plain water strong enough to cleave the carbon-fluorine bonds in PFAS, a chemical-free route to breaking down “forever chemicals” that until recently seemed indestructible. And a Kyushu University group turned that logic upside down with a solid-state material that upconverts ordinary visible sunlight into ultraviolet, a new energy source for air purification and photocatalysis that doesn’t require lamps or grid electricity.

Materials of biological origin took a step out of the pilot plant and into the marketplace. Bottega Veneta released a limited collection of Intrecciato small leather goods woven from Ephea Uma, the mycelium-based material from Italian startup Sqim, giving a heritage luxury house’s craft tradition to a mushroom-grown material. And Perfect Day confirmed that its Gujarat precision-fermentation plant is on track to begin producing recombinant whey protein this year, one of the largest animal-free dairy facilities anywhere.

Local infrastructure and older, still-load-bearing breakthroughs rounded out the week. PetStar and Bepensa opened a new circular-economy transfer center on the Mexican island of Holbox, a small facility with an outsize educational role in Mexico’s first zero-waste pilot. And the University of Rochester’s laser-textured solar desalination panel, unveiled in late May and continuing to draw attention, quietly reframes desalination brine from a disposal problem into a mineable feedstock. Together, the week’s items suggest a resource-abundance story less about single miracle materials and more about redesigning the loops through which existing atoms move.

Cornell’s Electrochemical Bath Regenerates Spent EV Battery Electrodes to 95% Capacity

A Cornell team led by Lynden Archer has demonstrated a battery-recycling technique they call Direct Electrode-to-Electrode Regeneration, or DEER. Rather than shredding a spent lithium-ion cell and smelting the fragments to recover raw metals — the dominant industrial approach — DEER opens the cell, removes the electrodes intact, and soaks them in a solvent (1,3-dimethyl-2-imidazolidinone) that dissolves the solid-electrolyte-interphase layer accumulated during charging cycles.

After the bath, the electrodes recover up to 95% of their original capacity and can be reassembled into new cells. In their calculations, published on June 9 in Energy & Environmental Science, the researchers estimate the process would cut recycled-cell manufacturing cost by 56% while sharply reducing water use and air pollution compared with pyrometallurgical or hydrometallurgical recycling.

The economics matter because current recycling routes destroy the electrode’s careful nanostructure — the same structure the industry spends enormous energy building in the first place. If DEER scales, the same physical piece of cathode material could ride out multiple battery lives.

Cornell has filed for intellectual-property protection, and the team is now working on scaling to larger battery packs and adapting the chemistry to address permanent lithium loss, not just interphase buildup. Trade coverage this week noted that regenerating electrodes in-place would also shorten the effective critical-minerals supply chain for the United States.

Stegra Closes $1.6 Billion Financing for Europe’s Flagship Green-Steel Plant

Stegra — formerly H2 Green Steel — announced on June 24 that it had completed a €1.4 billion (roughly $1.6 billion) financing round led by a Wallenberg Investments consortium, with continued participation from Temasek, Hy24, Just Climate and Altor. The proceeds keep construction of the company’s Boden, Sweden plant on track; when finished, it is expected to be Europe’s largest primary green-steel facility, replacing coal-based blast-furnace reduction with hydrogen produced from renewable electricity.

The financing is significant beyond its size. Green-steel projects globally have faced a slowdown over the past year as fossil steel prices declined and customer offtake terms hardened. Stegra’s ability to close a nine-figure round in that environment — with several existing investors doubling down — reads as a vote of confidence in Boden as the credible near-term test case for the technology.

The plant is designed to use direct-reduced iron produced with hydrogen from an on-site electrolyzer, followed by electric-arc-furnace melting. If commissioned on schedule, Stegra’s Boden operations will be one of the first industrial-scale demonstrations that steel can be made without the coke ovens that have anchored the industry since the nineteenth century.

Volvo and Scania have previously signed multi-year offtake agreements for near-zero-emissions steel from the plant, effectively pulling their own supply-chain decarbonisation forward. The financing announcement suggests the project’s counterparties see the same trajectory.

Bottega Veneta Weaves Mycelium Leather into Its Signature Intrecciato

Bottega Veneta unveiled a limited collection of six small leather goods this month made from Ephea Uma, a mycelium-based material developed by the Italian biomaterials startup Sqim. The pieces use the house’s signature Intrecciato — a hand-woven strap-braiding technique that has defined its craft identity since 1975 — applied for the first time to a material grown from fungal roots rather than tanned from an animal hide.

Sqim’s Ephea is produced by cultivating fungal mycelium into a dense, hide-like mat, which is then finished in Italy using techniques adapted from traditional leather-making. The result behaves mechanically similarly enough to leather that it can be cut, dyed and — as the collection demonstrates — braided by hand without breaking.

The launch is more than a novelty. Kering, Bottega Veneta’s parent group, deepened its involvement with Sqim earlier this month, and the Intrecciato collaboration was announced as part of the Fall 2026 men’s collection under new creative director Louise Trotter. That places a mycelium material inside the design system, rather than positioning it as an “eco” alternative in a separate line.

For the alternative-materials industry, the story is a familiar shape: sustained R&D by a small European startup finally graduates into a headline-grabbing luxury deployment. The interesting question is whether the artisanal Intrecciato technique — which depends on a very specific balance of stiffness and pliability — can survive the transition to volume production of the underlying material.

Aarhus Team Uses UV-Generated Hydrogen Radicals to Break Down PFAS Without Reagents

A team at Aarhus University’s Centre for Water Technology, led by Zongsu Wei with Lu Bai and Shuang Luo, has published new mechanistic evidence for a chemical-free route to destroying per- and polyfluoroalkyl substances — the “forever chemicals” whose extreme stability against heat, light and reactive species has made industrial-scale destruction so difficult.

The Aarhus group directed intense ultraviolet light, at wavelengths below 300 nanometres, into ordinary water containing PFAS molecules. The energetic photons dissociate water molecules and generate hydrogen radicals — highly reactive single-hydrogen fragments — that can attack the carbon-fluorine bonds at the heart of PFAS. In laboratory tests, GenX, one of the more widely used “short-chain” PFAS replacements, showed up to 49.1% degradation and 21.2% defluorination within five hours of exposure, without any added chemical reagents.

That is a mechanistic result rather than a deployable water-treatment technology, but it is significant. Most existing PFAS approaches — activated-carbon capture, ion-exchange resin, incineration — either concentrate the pollutants or move them somewhere else. A reagent-free photolytic pathway offers, for the first time, a plausible route to breaking the carbon-fluorine bond at the point of collection.

Aarhus’s next steps focus on scaling the light-source geometry and on characterising the reaction products to confirm that intermediate breakdown compounds are themselves benign. The work was published in Environmental Science & Technology.

Precisely One-Nanometre Pores: A New Membrane for Ultra-Selective Water Filtration

An international collaboration between India’s CSIR-Central Salt and Marine Chemicals Research Institute, IIT Gandhinagar, Nanyang Technological University in Singapore, and the S. N. Bose National Centre for Basic Sciences has developed a new class of membranes whose separating layer is built from polyoxometalate (POM) clusters — inorganic molecular cages with a naturally occurring central opening exactly one nanometre wide.

Conventional nanofiltration membranes rely on statistical pore-size distributions in polymer films. Getting truly uniform sub-nanometre pores has been one of the field’s long-standing challenges, because most fabrication routes yield a spread of hole sizes that limits sieving precision. The POM-cluster approach sidesteps that problem: every pore is atomically identical, and the geometry is fixed by chemistry rather than by post-processing.

The team reported that their membranes deliver sharp size-based separation of small molecules with high water permeance, and that the POM framework remains stable under the operating conditions typical of pharmaceutical purification and textile wastewater treatment. The membranes also filter salts and organic pollutants with markedly less pressure — and therefore less energy — than commercial reverse-osmosis or nanofiltration alternatives.

If the process can be adapted from lab coupons to industrial rolls, the implications reach beyond drinking water. Ultra-selective separations are the bottleneck in recycling lithium and cobalt from mining brines, purifying biopharmaceutical intermediates, and reclaiming solvents from industrial waste streams. Precise pores are a rare commodity.

Kyushu Researchers Make Ordinary Sunlight into UV with a Solid-State Upconverter

A team at Kyushu University reported on June 23 in Nature Communications a molecular solid-state material that converts visible sunlight into ultraviolet light through a process called triplet-triplet-annihilation photon upconversion. In effect, two visible-light photons are combined into one higher-energy UV photon; the team measured a conversion efficiency of 1.9%, meaning roughly two UV photons emerge for every hundred visible photons absorbed.

Photon upconversion is not new, but making it work under sunlight — as opposed to laser illumination — and inside a stable solid has been technically difficult. The Kyushu material is synthesised from inexpensive starting reagents and requires no exotic conditions to operate, opening the door to devices that use plain sunlight as a UV source.

The practical significance is that UV is currently generated almost entirely by grid-powered lamps, most of which use mercury vapour or specialised LEDs. Applications include air and water disinfection, dental and orthopaedic curing, semiconductor lithography and photocatalytic chemistry. A passive material that harvests UV directly from the sun could remove electricity — and, in the case of mercury lamps, hazardous materials — from those workflows.

The Kyushu group frames the result as a first step: 1.9% efficiency is enough to drive small photocatalytic reactions but not yet enough to displace lamp-based UV in the field. The interesting near-term application is likely to be low-intensity, high-selectivity photochemistry, where a passive sunlight-driven source is worth more than a factor of two in photon flux.

Holbox Zero-Waste Center Opens as Mexico’s First Circular-Economy Pilot

Mexican Coca-Cola bottlers PetStar and Bepensa Beverages, working with the industry consortium ECOCE, opened a new circular-economy transfer center on the Yucatan-coast island of Holbox on June 26. Holbox — a small, car-free tourist island with no permanent bridge to the mainland — has been chosen as the pilot site for Holbox Circular, a three-year initiative launched in 2024 to build Mexico’s first zero-waste circular-economy model.

The new center accepts plastic, aluminum, cardboard and glass, sorts the streams on-island, and consolidates them for transport back to the mainland for recycling. Because the island’s waste-management logistics were previously dominated by simply moving mixed refuse across the water, on-site separation is a much larger operational change than it looks: material that had effectively been landfilled elsewhere is now brought back into recycling supply chains.

The project’s design reflects a shift in how bottlers are approaching post-consumer PET. Rather than treating recycling as a downstream cost, Arca Continental (parent of PetStar) has framed the Holbox center as an educational and behaviour-change asset — one that gets visitors to a heavily touristed island to see the loop between the bottle they buy and its downstream use. A separate PetStar visitor centre opened in Nuevo León earlier in June with similar goals.

Small-island circular-economy pilots have often been treated as showcases rather than templates, but the Holbox model — a bottler-funded transfer center with clear commercial recovery in mind — is one of the more replicable examples so far.

Perfect Day’s Gujarat Facility on Track for Late-2026 Start of Animal-Free Whey Production

Perfect Day, the California-based precision-fermentation company that pioneered recombinant whey-protein production, confirmed this month that its joint-venture facility with Zydus Wellness in Gujarat, India, is on schedule for commissioning in the second half of 2026, with a “controlled ramp-up” through 2027. When at full run rate, it will be one of the largest precision-fermentation dairy facilities globally.

Perfect Day’s process uses engineered microbes to produce beta-lactoglobulin — the same whey protein present in cow’s milk — without the cow. Fermenter production takes days rather than the months required to raise a dairy animal, uses a fraction of the water and land, and avoids methane emissions from ruminant digestion. The resulting protein is chemically identical to the animal-derived version, which means existing dairy formulations can be reformulated without changing the end-product texture or nutritional profile.

India was a strategically deliberate choice. It is the world’s largest dairy producer and consumer, has a maturing biomanufacturing base and — critically — a large vegetarian consumer segment that has historically been well-served by dairy but not by conventional plant-based dairy analogues. Perfect Day’s whey protein is compatible with vegetarian diets and doesn’t require the flavour compromises of plant-based casein substitutes.

The Gujarat commissioning also matters for the industry’s cost curve. Precision-fermentation companies have long argued that per-kilogram protein costs will fall as fermentation scale grows and utility contracts get better; a plant of this size is the first serious test.

Rochester’s Laser-Textured Desalination Panel Turns Brine into a Feedstock

A Rochester University team led by Chunlei Guo unveiled a solar desalination panel that combines two design ideas that had previously been considered incompatible: it uses only sunlight to evaporate seawater, and it produces no toxic brine stream. Rather than concentrating salt into a hard-to-dispose liquid, the panel deposits dissolved solids as dry crystals on a passive region of the panel surface, where they can be swept off and reused.

The panel is made from black metal — copper or aluminium — that has been textured with a femtosecond laser to create a nano-patterned surface that is simultaneously super-absorbent to sunlight and super-wicking to water. A thin film of seawater flows across the illuminated active region, evaporates rapidly, and the salts diffuse laterally to the untreated passive edges rather than clogging the working surface. Tests on water from three different oceans showed sustained operation without the salt-fouling that plagues most solar-still designs.

Because the recovered solids can be mined for lithium, potassium and other high-value minerals, the panel reframes desalination brine from waste to feedstock. In coastal areas near lithium-rich seawater, that could turn a water-treatment plant into a mineral producer with only sunlight as input.

According to the United Nations, 2.2 billion people still lack safely managed drinking water; the Rochester group frames their design not as a replacement for large industrial desalination plants, but as a modular, off-grid option for the smaller-scale contexts where centralised infrastructure has not been built.

QuantumScape and Honda Formalise Solid-State Battery R&D Partnership

QuantumScape and Honda R&D announced on June 18 a joint research agreement to advance QuantumScape’s solid-state lithium-metal battery technology. The multi-year program covers both cell development and manufacturing-process refinement — a notable framing, because most of the past decade’s solid-state coverage has focused almost exclusively on cell chemistry rather than on how to build large volumes of cells reproducibly.

The Honda deal follows a detailed technical evaluation phase in which Honda’s research division tested QuantumScape’s cells hands-on and benchmarked them against conventional lithium-ion cells. Honda concluded that the technology’s energy-density and safety advantages justified a formal partnership, joining Volkswagen as QuantumScape’s second major automotive OEM.

QuantumScape’s specific architecture uses a ceramic separator between a lithium-metal anode and a lithium-metal-oxide cathode, with the anode self-forming during the cell’s first charge. That eliminates the need to manufacture and handle metallic lithium as a discrete step — historically one of the hardest parts of building a solid-state cell — but pushes the difficulty into the ceramic separator, which must remain flat and defect-free at scale.

Solid-state batteries promise higher energy density, faster charging, wider operating-temperature ranges, and — most importantly — reduced fire risk relative to today’s liquid-electrolyte lithium-ion cells. Whether the technology becomes real for consumer vehicles depends primarily on manufacturing yield. The QuantumScape-Honda framing suggests the industry now sees that as the binding constraint.
