    Ascend and Koura to recycle battery graphite

    [ad_1]

    The battery recycler Ascend Elements will work with the fluorine chemical firm Koura—whose parent company, Orbia, has invested in Ascend—to commercialize technology for recycling graphite anode material in batteries. Some battery recycling processes can recover graphite, but Ascend claims that the product isn’t usually pure enough for batteries. Graphite has received less attention from recyclers because it’s less valuable than cathode metals like cobalt, lithium, and nickel. Orbia is also working with Ascend to recycle fluorine chemicals in batteries.

    From left: Pat Ward, Paul Anastas, Gregory Constantine, Mahlet Garedew, and Stafford Sheehan of the Air Company, the winner in the specific environmental benefit—climate change category, stand in front of the National Academy of Sciences holding their Green Chemistry Challenge Award.

    On Oct. 23, the US Environmental Protection Agency announced the winners of this year’s Green Chemistry Challenge Awards during a ceremony at the National Academy of Sciences in Washington, DC. One academic researcher and five companies were recognized for efforts including transforming waste products into useful materials and creating greener industrial processes.

    “The Green Chemistry Challenge Awards demonstrate how sustainable alternatives in chemistry are flourishing and improve upon traditional methods,” Albert G. Horvath, CEO of the American Chemical Society, says in a press release.

    “Green chemistry can play a vital role in protecting human health and the environment by increasing efficiency, avoiding hazardous chemicals and preventing waste while improving the competitiveness of American companies,” Jennie Romer, deputy assistant administrator at the EPA Office of Chemical Safety and Pollution Prevention, says in the EPA’s press release.

    Richard Laine, a professor of materials science and engineering and macromolecular science and engineering at the University of Michigan, won in the academic category for developing new ways to upcycle agricultural waste, like rice hulls or corn husks, into materials suitable for next-generation energy storage technologies. People burn millions of metric tons of agricultural waste for fuel each year; the burned biomass produces a silica-rich ash. Laine’s latest method for refining this ash involves a reaction that ultimately makes spirosiloxane, which can be used to create lithium-ion-conducting polymers for use in solid-state batteries. He is also working to turn the leftover silica-depleted ash into electrodes for lithium-ion supercapacitors.

    The EPA gave the award in the design of greener chemicals category to Clorox for designing EcoClean, a lactic acid–based disinfectant cleaner. Lactic acid is biodegradable and can be produced from renewable sources through fermentation. The company reports that EcoClean killed viruses and bacteria as effectively as traditional disinfectants during testing. The Clorox EcoClean bottles also contain a minimum of 25% postconsumer recycled plastic.

    In the greener reaction conditions category, the emission control technology developer Captis Aire was recognized for its chemical adsorption innovation reduces emissions (CAIRE) technology. The company says CAIRE captures over 90% of odorous terpenes produced at wood manufacturing sites that process materials such as wood pellets, plywood, and lumber. These terpenes can be irritants. The captured terpenes are turned into valuable chemicals for use in products such as biofuels, flavors, and fragrances.

    The sustainable chemical start-up Solugen won in the greener synthetic pathways category for creating the Bioforge. This manufacturing platform uses enzymatic and catalytic processes to convert plant-derived substances into chemicals that are traditionally made from fossil fuels. The company currently produces several different molecules from corn sugar, including hydrogen peroxide and glucaric acid, the latter of which is used in dishwasher detergents to boost their cleaning power.

    The EPA gave the award in the small business category to the biotechnology company Modern Meadow for developing its bio-fast resource efficient enhanced dyeing (Bio-FREED) technology. Bio-FREED uses a mixture of plant-based proteins and biopolymers to eliminate inefficiencies in dyeing processes. The company says its technology uses 95% less water, 75% less energy, and 80% fewer dyes and chemicals than traditional dyeing methods.

    In the specific environmental benefit–climate change category, the carbon utilization start-up Air Company was recognized for its Airmade technology. Airmade’s only starting materials are carbon dioxide captured from industrial plants and hydrogen produced by the electrolysis of water. It uses a catalytic process to transform these into a mixture of alcohols, alkanes, and water, which are separated by distillation. The only by-product is oxygen. Airmade products on the market so far include sustainable aviation fuel, ethanol, and methanol. The company says the carbon dioxide emissions of the full life cycle of its sustainable aviation fuel are at least 90% lower than those of traditional jet fuel.

    Since its inception in 1996, the EPA Green Chemistry Challenge Awards program has acknowledged companies and academics that have incorporated green chemistry principles into the design, manufacture, and use of chemicals. The EPA Office of Chemical Safety and Pollution Prevention sponsors the program in partnership with the ACS Green Chemistry Institute and other members of the chemical community.

    The EPA is accepting nominations for the 2024 Green Chemistry Challenge Awards. To learn more about next year’s award categories and how to apply, visit epa.gov/greenchemistry. Nominations are due Dec. 8.

    Vinyl records could be things of the past

    [ad_1]

    South Korea’s SK Chemicals and Sonopress, the manufacturing subsidiary of the German media company Bertelsmann, have developed a material for making records that might replace the polyvinyl chloride used for decades. The new records are made from recycled polyethylene terephthalate, which SK processes chemically at a plant in China. Sonopress has been trying to find an alternative to vinyl for 2 years; for the new record, it developed an injection molding machine that exerts a pressure of 300 metric tons.

  • New method spots unreported forever chemicals

    New method spots unreported forever chemicals

    [ad_1]

    Located along the Cape Fear River, about 100 miles upstream of Wilmington, North Carolina is a Chemours fluoropolymer plant.

    Researchers have identified new PFAS downstream of Chemours’s fluoropolymer plant in North Carolina.

    Per- and polyfluoroalkyl substances (PFAS) are ubiquitous synthetic chemicals found in the air, water, and soil. They have contaminated drinking water, accumulated to levels of concern in some fish, and entered the bloodstreams of animals and humans, raising serious health concerns.

    While some PFAS are being phased out, they’re often replaced with new ones that may also be toxic. Finding and keeping track of these emerging PFAS is challenging. New research has found a way to detect them.

    Most commercial laboratories target about 40 PFAS, “but we know many, many more exist,” says Erin Baker, an analytical chemist at the University of North Carolina at Chapel Hill. The US Environmental Protection Agency, for example, maintains a list of more than 14,000 PFAS that may be used in making products resistant to oil, water, and heat. The problem is that “there’s only a few hundred chemical standards available to validate that you’re actually seeing these chemicals,” Baker says, “so we’re missing over 13,000.”

    Along with her colleagues, Baker developed a new approach to detect PFAS that conventional methods may miss. It harnesses previously used techniques, such as liquid chromatography and high-resolution mass spectrometry, to identify different molecules in a mixture according to their mass, solubility, and polarity.

    Chemical structures of previously unreported PFAS chemicals in the Cape Fear River.

    In a novel addition, the research team used ion mobility spectrometry to distinguish these molecules on the basis of their size and shape. “They’re putting together a bunch of techniques that not everybody does,” says EPA research scientist Mark Strynar, who was not involved in the research. “It is cutting edge; it is different and unique.”

    This multidimensional approach helped Baker and her team detect 36 known and 11 previously unreported PFAS in North Carolina’s Cape Fear River. Eight of them weren’t on EPA’s list (Sci. Adv. 2023, DOI: 10.1126/sciadv.adj7048). “I was really shocked that we found these novel chemicals,” Baker says. “It shows that there’s a lot more out there that we’re missing and why such nontargeted analyses are so important.”

    The work involved deploying passive samplers—embroidery hoops with two pieces of mesh and resin beads that bind PFAS—upstream and downstream of the Chemours chemical plant in 2016 for 2 weeks. Chemours, along with former company owner DuPont, has attracted lawsuits and millions of dollars in fines for decades of dumping PFAS into the Cape Fear River.

    “Most PFAS we found are most likely coming from the company based on what we know they’re making and their patent literature,” says coauthor and environmental chemist Kaylie Kirkwood- Donelson, formerly a PhD student at North Carolina State University.

    While researchers are yet to understand if the new PFAS pose health risks, known examples, such as GenX, a member of the PFAS family that they detected, have been linked to issues with the liver, the kidneys, the immune system, and potential cancer risks on the basis of animal studies. Baker and Kirkwood-Donelson hope their method can help pinpoint novel chemicals lurking in the environment whose toxicity can later be tested in the laboratory.

    But their approach can’t quantify the amounts of such PFAS in the water. Also, ion mobility spectrometry is extremely expensive and not easily accessible. But “a decade ago, high-resolution mass spectrometry was not the norm,” Strynar says. “A decade from now, maybe ion mobility spectrometry is something more people will have access to,” he adds. That could help more PFAS be detected more frequently.

  • China restricts exports of graphite used to make battery anodes

    China restricts exports of graphite used to make battery anodes

    [ad_1]

    China’s commerce ministry has put the world’s battery industry on notice by restricting the export of some graphite materials that are used to make anodes for lithium-ion batteries. The move is calling attention to China’s dominance of the market and providing a push to establish graphite processing outside the country.

    Graphite anodes can be produced from synthetic graphite—made by heating petroleum coke—or from mined graphite flakes. Graphite flakes must be milled into spherical particles and then coated with carbon. Both forms are mixed with binders to create a battery anode.

    Starting in December, companies in China will have to get permission to export some forms of natural and synthetic graphite materials that are used to make anodes.

    Over 60% of the world’s mined graphite and nearly half of synthetic graphite is produced in China, according to the US Geological Survey. The country also dominates processing steps further down the supply chain. The research firm Benchmark Mineral Intelligence estimates that Chinese firms produce 99% of spherical graphite and 93% of all graphite anode materials.

    James Willoughby, a graphite analyst with the consulting firm Wood Mackenzie, says the restriction demonstrates China’s control of the graphite market but may not significantly slow battery makers outside China.

    Over the summer, the country placed similar restrictions on the export of gallium and germanium. While that caused a slowdown in trade for several months, exports have started again, Willoughby says. “It doesn’t seem like they’ve turned off the tap,” he says. “They just wanted to sort of show that they have control.” He says the graphite market might follow a similar path.

    Even before the export restrictions, several companies had announced intentions to establish graphite mining and processing or anode material production outside China.

    Westwater Resources is planning a graphite mine and processing facility in Alabama. With financial support from the US government, Syrah Resources is nearing completion of a plant in Louisiana that will produce anode material from natural graphite. The company says it already has customers. Both firms expect Chinese export restrictions to boost their business.

    Graphex Technologies is building facilities in Michigan that will produce spherical and carbon-coated natural graphite. CEO John DeMaio says the Chinese restrictions only emphasize the need for what the company already has planned. “We saw the size of the opportunity here in North America,” he says. “We knew there was going to be a need for a localized supply chain.”

    But it won’t be easy for battery makers to transition to a battery anode supply chain that avoids China, according to Daisy Jennings-Gray, an analyst with Benchmark. She says it will take a long time to build anode production capacity and get the material qualified by battery makers.

    “This announcement has certainly put graphite, and anodes, on the radar in the West,” she says. “There won’t be a quick pivot away from the reliance on graphite and anodes from China.”

  • Beam Therapeutics lays off staff, adjusts research focus

    Beam Therapeutics lays off staff, adjusts research focus

    [ad_1]

    Gene editing company Beam Therapeutics became the latest biotech to announce staff layoffs Oct. 19. The firm plans to lose 100 employees–20% of its workforce. The company, based in Cambridge, Massachusetts, also says it will cut back on its pipeline. The cost savings from these changes will keep the lights on into 2026, the company says.

    Chemist David R. Liu at the Broad Institute of MIT & Harvard, launched Beam in May 2018, two years after Liu’s lab developed base editors, the company’s key technology. Base editors deliver a twist on traditional CRISPR-Cas gene editing to make single nucleotide base changes in DNA. In theory, this technology enables the treatment of genetic diseases with more precision and with fewer off-target effects.

    But despite base editing’s potential, it’s taking time for the technology to yield a clinical product. Beam’s restructuring will pause the development of an in vivo treatment for hepatitis B virus. The company will also seek partners for further developing its CAR T-cell immunotherapy for T-cell leukemia and T-cell lymphoblastic lymphoma.

    Instead, Beam will focus on its leading therapeutic candidate, a base editing therapy for sickle cell disease (SCD), and a second therapy that delivers hematopoietic stem cells to treat SCD. Investors have largely focused on the former, for which early clinical data should emerge early next year, sayss Sami Corwin, an analyst at William Blair, in a note to investors. Beam will also continue to pursue a base editor therapy for a metabolic disease called Alpha-1 antitrypsin deficiency, for which it aims to submit regulatory applications in the first quarter of 2024.

    A handful of other companies are developing gene therapies for sickle cell disease and two firms have already gone to the US Food and Drug Administration for approval of their products. That could limit the market for Beam’s alternative and the base editing platform will be critical to Beam differentiating itself, Corwin sayss.

    It has been a tough year for layoffs in the industry; 119 biopharma firms had cut staff by Aug. 18 this year, matching the number for the whole of 2022, according to analysis by Fierce Biotech.

    “In this challenging market environment,” says John Evans, CEO of Beam, in a statement accompanying the announcement, “we need to make the difficult decision to focus our resources on those clinical programs and research areas we believe have the highest potential for near-term value creation, while continuing to build a strong company for the future.”

  • NIH revamps grant review process to reduce bias

    NIH revamps grant review process to reduce bias

    [ad_1]

    As part of a decade-long effort to level the playing field for investigators seeking money to pursue biomedical research, the US National Institutes of Health is simplifying its grant review process. Expertise and resources—two factors that can lead to potential reputation bias—will be evaluated for sufficiency but will no longer get a numerical score, the agency announced Oct. 19.

    The new framework, which goes into effect for grant applications received on or after Jan. 25, 2025, is designed to give more weight to the importance, rigor, and feasibility of a proposed research project. Such factors will continue to be scored numerically.

    “Studies have shown that consideration of reputation of the institution or investigator in the grant review process could affect assessment of scientific merit, potentially giving reputation greater weight than other factors,” Lawrence Tabak, acting director of the NIH, says in a statement. “Ultimately, the potential impact of ideas on advancing science should outweigh the reputation of who is applying and where they work.”

    The NIH has been struggling for years to make its grant review process fair and to ensure that peer review panels choose the best research proposals. The new framework also shifts some of the administrative burden from peer reviewers to NIH staff to allow reviewers to focus more on the science.

    The NIH says it will consider feedback on the new framework. It will also collect data to evaluate the impact of the changes over time so that it can improve the process as needed.

  • Shell seeks damages in ethylene cartel case

    Shell seeks damages in ethylene cartel case

    [ad_1]

    Shell Chemicals Europe has filed a claim for approximately $1 billion in damages in the District Court of Amsterdam against four companies that the European Commission found in 2020 to be operating a buyer’s cartel for ethylene. One of the companies, Clariant, issued a statement rejecting the allegations, claiming that Shell was not one of its ethylene suppliers.

    The EC that year found that Clariant, Celanese, Orbia, and Westlake Chemical fixed the price they paid for ethylene in Belgium, France, Germany, and the Netherlands between December 2011 and March 2017. Clariant was fined $175 million, Celanese $93 million, and Orbia $25 million.

    Westlake would also have been fined for price-fixing had it not alerted the commission to the cartel activities.

    “As a supplier of ethylene to the European market, we have a significant claim against the companies that were found by the European Commission to be operating a buyer’s cartel,” Shell says in a statement on its filing. “We have started litigation proceedings against them to recover these substantial damages from the impact their price manipulation has had on our business.”

    In a statement responding to Shell’s Oct. 18 filing, Clariant says it “rejects the allegation and will adamantly defend its position in the proceedings.” Clariant adds that it possesses “substantiated economic evidence that the conduct of the parties did not produce any effect on the market.”

    Celanese, Orbia, and Westlake did not immediately respond to requests for comment.
