New method converts food waste into plastic and organic fertilizer
Researchers at Binghamton University, led by PhD student Tianzheng Liu and supported by Professors Sha Jin and Kaiming Ye, have developed an innovative microbial process that converts food waste into biodegradable plastic and organic fertilizer. Using the bacteria Cupriavidus necator, which synthesizes polyhydroxyalkanoate (PHA) from fermented food waste containing lactic acid and ammonium sulfate, the team can harvest about 90% of the bioplastic produced. This method addresses two major environmental issues simultaneously: the massive food waste in landfills that emits greenhouse gases and the growing problem of plastic pollution. The process is robust and adaptable, working with various types of food waste as long as the mixture ratios remain consistent, and the waste can be stored for at least a week without impacting results. The leftover residue from fermentation is also being evaluated as an organic fertilizer alternative to chemical fertilizers. The researchers aim to scale up the system for industrial application, seeking partnerships and additional funding to expand the

Researchers at EPFL and Kyoto University have developed the first hydride-based deep eutectic solvent (DES), a hydrogen-rich liquid stable at room temperature that could revolutionize hydrogen storage. This liquid is created by mixing ammonia borane and tetrabutylammonium borohydride in specific ratios (50%-80% ammonia borane), resulting in a transparent, stable liquid containing up to 6.9% hydrogen by weight—surpassing the US Department of Energy’s 2025 hydrogen storage target. The DES remains liquid due to strong hydrogen bonding disrupting the crystalline structure of the individual components, and it does not crystallize even when cooled below −50°C, instead undergoing a glass transition. This new hydrogen storage medium offers significant advantages over existing methods, which rely on high-pressure gas compression or cryogenic cooling, both energy-intensive and cumbersome. The liquid releases pure hydrogen gas at a relatively low temperature of 60°C, requiring less energy than many solid-state storage materials, and only the

The article highlights an innovative approach to reducing pollution from maritime shipping, a sector responsible for about 3% of global carbon emissions. London-based company Seabound has developed a retrofit technology that captures carbon dioxide emissions from a ship’s existing internal combustion engines and converts the CO2 into limestone, a key ingredient in cement. This system is currently installed on the UBC Cork, a cement carrier sailing in the Mediterranean. The limestone produced during the voyage will be offloaded in Norway and used at Heidelberg Materials’ net-zero cement plant in Brevik, thereby closing a carbon loop between shipping and cement production—two industries that together contribute roughly 11% of global emissions. The technology offers a practical alternative to other decarbonization methods like batteries or ammonia fuel, which either lack sufficient energy density for long voyages or require extensive engine overhauls. Seabound’s retrofit allows ships to maintain their existing engines while capturing emissions directly from exhaust pipes. This innovation aligns with the International Maritime Organization’s (IMO

Apple has committed $500 million in a multi-year deal with MP Materials, the only U.S.-based company that mines, processes, and manufactures rare earth materials entirely domestically. This partnership aims to reduce reliance on China for critical rare earth elements, especially neodymium magnets used in Apple devices. As part of the agreement, Apple will purchase American-made magnets from MP Materials’ expanded Independence facility in Texas, which will feature new manufacturing lines tailored for Apple products and is expected to begin global supply by 2027. The expansion will create advanced manufacturing and R&D jobs, alongside training programs to build U.S. expertise in rare earth magnet production. Additionally, Apple and MP Materials will establish a state-of-the-art rare earth recycling plant at the Mountain Pass facility in California to recover materials from electronic waste and industrial scrap, further integrating recycled rare earths into Apple’s supply chain. This initiative builds on Apple’s prior use of recycled rare earth elements since 2019 and supports its broader commitment to invest

A collaborative team of scientists from multiple U.S. Department of Energy national laboratories, led by the National Renewable Energy Laboratory (NREL), has uncovered how light activates nickel-based catalysts to drive chemical reactions while preserving their reactivity. Published in Nature Communications, the research reveals that exposure to light breaks a bond in nickel dihalide catalysts, lowering nickel’s oxidation state and making it reactive. Crucially, the freed halide ion (chlorine radical) interacts with the solvent to form a previously unknown, stable nickel intermediate. This intermediate prevents the reactive nickel atoms from binding to each other and deactivating, thereby maintaining the catalyst’s activity. This discovery advances understanding of light-driven nickel catalysis, which offers advantages over traditional palladium catalysts, including lower cost, milder reaction conditions, and the ability to facilitate novel chemical transformations. Nickel is significantly cheaper than palladium—about 50 cents per ounce versus nearly $1,000 per ounce for palladium—and can be activated by light rather than heat

Researchers at Chung-Ang University in South Korea have developed a novel air filtration system inspired by the mucus layer in the human nose, which naturally traps dust, allergens, and harmful particles. This bioinspired filter, called the particle-removing oil-coated filter (PRO), uses a thin, stable film of biocompatible oil (200 to 500 nanometers thick) applied to standard filter fibers. This coating mimics the sticky mucus barrier and enhances particle capture through capillary adhesion, significantly improving retention compared to conventional filters that rely on weaker van der Waals forces. Field tests conducted in various indoor environments in Seoul, including offices, exhibition centers, and stadiums, demonstrated that the PRO filter not only traps more airborne pollutants but also lasts twice as long as traditional filters. Additionally, its sticky oil layer prevents particles from being dislodged by strong winds, making it suitable for high-airflow locations such as construction sites and metro stations. The filter is compatible with existing HVAC and air purifier systems

New Zealand-based Aspiring Materials has developed a patented chemical process that extracts valuable battery metals—specifically nickel-manganese-cobalt (NMC) hydroxide—from the mineral olivine without generating waste or carbon dioxide emissions. This innovation addresses the traditionally low economic value of olivine by transforming it into critical materials used in lithium-ion batteries for electric vehicles and energy storage, while also supporting industrial decarbonization efforts. The process yields multiple products: about 50% silica, usable as a partial substitute for Portland cement; roughly 40% magnesium products applicable in carbon sequestration and wastewater treatment; and the remaining 10% comprising iron combined with NMC hydroxide. Beyond carbon capture, this approach enables broader utilization of olivine-derived minerals, potentially reducing reliance on international supply chains for critical battery metals. Aspiring Materials has completed the first phase of its pilot plant and is expanding capacity to produce up to 250 kg of product daily, advancing domestic, low-carbon production of essential

Researchers have developed a lignin-based film separator derived from wood that significantly enhances the safety and longevity of lithium-ion batteries (LIBs), particularly for electric vehicles (EVs) and portable electronics. This wood-based separator remains dimensionally stable at temperatures up to 300°C (572°F), outperforming conventional polyethylene and polypropylene separators that suffer from thermal shrinkage and instability. The lignin film prevents internal short circuits and thermal runaway, reducing fire risks, while also extending battery cycle life by 60%, meaning the battery can be charged and discharged many more times before degrading. The lignin separator is produced using a solvent-free dry process, which is environmentally friendly and scalable, generating no waste or emissions. Made from lignosulfonate—a natural polymer byproduct of pulping and biorefinery—the film is thin (about 25 micrometers) yet effective at maintaining battery stability. This sustainable manufacturing approach not only reduces environmental impact but also leverages abundant natural materials without additional processing. Overall

A recent study from Brandon University, led by Dr. Bryan Cassone, reveals that waxworms—the caterpillars of the greater wax moth—can rapidly degrade polyethylene, the most common plastic worldwide. Remarkably, about 2,000 waxworms can consume an entire polyethylene bag within 24 hours, a process that normally takes decades or centuries in the environment. The research shows that waxworms metabolize the plastic into lipids stored as body fat, similar to how humans store fat from food. However, an all-plastic diet is lethal to the caterpillars, causing mass loss and death within days. Cassone suggests that co-supplementing their diet with other food sources could sustain and even enhance their health, enabling mass rearing. The implications of this discovery are twofold: waxworms could be farmed on a supplemented polyethylene diet to help reduce plastic waste as part of a circular economy, or scientists could isolate and replicate the enzymes responsible for plastic degradation in laboratory or industrial settings

A recent international study led by Kiel University highlights the potential of lithium-sulfur batteries (LSBs) to revolutionize electric vehicle (EV) charging by enabling full charges in as little as 12 minutes, significantly faster than current lithium-ion batteries that typically require 20 to 30 minutes for partial charges and longer for full ones. LSBs offer a theoretical energy density of up to 2,600 watt-hours per kilogram—nearly ten times that of conventional lithium-ion cells—due to their sulfur cathode paired with a metallic lithium anode. This could translate to much longer driving ranges and help alleviate range anxiety, a major barrier to EV adoption. Additionally, sulfur is abundant, eco-friendly, and cost-effective compared to cobalt and nickel used in lithium-ion batteries. Despite these advantages, LSB technology faces several challenges. Sulfur’s poor electrical conductivity requires mixing with carbon-based materials, which adds weight and complexity. The sulfur cathode also undergoes significant volumetric changes during charging cycles

Researchers at the University of Tokyo have developed a novel synthetic polymer inspired by the natural loofah sponge, featuring a porous, loofah-like structure that is stronger than typical plastics yet lighter than foam. This innovative material exhibits remarkable mechanical properties, achieving a stiffness of up to 11 gigapascals at a low density of 0.5 grams per cubic centimeter—about four times stronger than conventional polymers. The polymer is pH-responsive, becoming more rigid or flexible depending on acidity, and its fine pore network (around 70 nm) allows fluids to pass while filtering and killing bacteria and viruses, making it highly suitable for filtration, structural applications, and potentially medical devices. The polymer is synthesized simply using water, applied voltage, and a mixture of resorcinol and an aldehyde, producing an ultrathin porous membrane without requiring post-processing. This process is scalable and compatible with roll-to-roll manufacturing, enhancing its industrial viability. Made from a lignin-like base, the material

Researchers at Harvard’s John A. Paulson School of Engineering and Applied Sciences have successfully grown green algae (Dunaliella tertiolecta) inside bioplastic pods designed to simulate Mars-like conditions. The team recreated Mars’ thin atmosphere, with pressure over 100 times lower than Earth’s, and used 3D-printed chambers made from polylactic acid bioplastic. These chambers effectively blocked harmful UV radiation while allowing enough light for photosynthesis. Despite the low atmospheric pressure that typically prevents liquid water from existing, the pods maintained a pressure gradient stabilizing water, enabling algae survival in a harsh, carbon dioxide-rich environment. This breakthrough suggests the potential for creating self-sustaining, closed-loop habitats on Mars, where bioplastic shelters could grow algae that in turn produce more bioplastic, enabling habitats to maintain and expand themselves over time. This biomaterial approach contrasts with traditional, resource-intensive construction methods by mimicking natural growth processes. Combined with previous innovations like silica aerogels to address

Scientists at IOCB Prague have developed an innovative water-only method to recycle rare earth elements, specifically neodymium and dysprosium, from discarded magnets. This breakthrough offers a cleaner, more cost-effective alternative to traditional recycling processes that rely on toxic solvents and generate hazardous waste. The new technique uses a specially designed chelator molecule that selectively precipitates neodymium while leaving dysprosium in solution, enabling efficient and environmentally friendly separation. This approach not only reduces environmental impact but also holds promise for industrial-scale application, supporting sustainable “urban mining” to meet the growing global demand for rare earths critical to technologies like smartphones and wind turbines. The technology, already patented, addresses key challenges in rare earth recycling and could help reduce dependence on geopolitically sensitive supply chains dominated by China. The research team, led by Miloslav Polášek and including doctoral candidate Kelsea G. Jones, is awaiting feasibility study results to transition the method from laboratory to commercial use.

A collaborative research effort involving the National Renewable Energy Laboratory (NREL), the University of Massachusetts Lowell, and the University of Portsmouth has advanced enzymatic recycling of polyethylene terephthalate (PET), a common plastic used in packaging and textiles. Building on prior work engineering improved PETase enzymes capable of breaking down PET, the team integrated chemical engineering, process development, and techno-economic analysis to create a scalable, economically viable recycling process. This approach addresses limitations of current PET recycling methods, particularly their incompatibility with low-quality, contaminated, or colored plastic waste, by using enzymes that selectively depolymerize PET into monomers that can be reused or upcycled into higher-value materials. Key innovations in the process include optimized reaction conditions and separation technologies that drastically reduce the need for costly acid and base additives by over 99%, cut annual operating costs by 74%, and lower energy consumption by 65%. These improvements have brought the modeled cost of enzymatically recycled PET down to $1.51 per kilogram

Australian researchers at Swinburne University of Technology, led by Dr. Yat Wong, have developed sustainable bricks made from spent coffee grounds (SCGs), offering a significant reduction in construction-related carbon emissions. By blending coffee waste with clay and an alkali activator, these bricks can be fired at just 200°C—about 80% lower than traditional brick firing temperatures—resulting in up to an 80% reduction in electricity-related CO₂ emissions per unit. This innovation not only diverts large quantities of coffee waste from landfills, thereby reducing methane emissions, but also produces bricks that exceed Australian minimum strength standards, making them both environmentally friendly and durable. Globally, around nine million tonnes of ground coffee are consumed annually, generating approximately 18 million tonnes of wet SCGs, much of which ends up in landfills contributing to greenhouse gas emissions. In Australia alone, over 1.3 million cups of coffee are sold daily, producing about 10,000 tonnes of coffee

Yale scientists, in collaboration with New Haven ceramic artist Kiara Matos, have developed a sustainable ceramic glaze made from eggshell waste, addressing the global issue of approximately 80 million metric tons of eggshells discarded annually. Eggshells, which are about 95% calcium carbonate, were processed by burning at 800°F to remove organic material, then ground into a fine powder to create ceramic glazes. These eggshell-based glazes were tested against traditional glazes made from mined calcium carbonate and found to have comparable, if not superior, qualities in appearance, durability, and resistance to wear and dishwasher cycles. The eggshell glaze demonstrated a smoother texture and vibrant color, prompting Matos to transition her pottery business entirely to this sustainable material. This innovation not only offers a practical reuse for eggshell waste—which can be hazardous and malodorous if untreated—but also promotes environmental sustainability by replacing mined materials with a renewable waste product. Matos sources eggshells from local bakeries and restaurants

Researchers at the Korea Institute of Science and Technology (KIST) have developed a biodegradable memory device that can reliably store data, endure over 3,000 bending cycles, and dissolve completely in water within three days. The device is based on a novel polymer called PCL-TEMPO, which combines polycaprolactone (a biodegradable material) with TEMPO, an organic molecule capable of electrical data storage. This innovation addresses the environmental challenge of electronic waste by offering a sustainable alternative that maintains strong data retention—distinguishing ON and OFF signals over one million cycles and retaining data for over 10,000 seconds—while also being fully biodegradable. A key feature of this technology is its biocompatibility and controlled degradation, making it suitable for medical implants that safely dissolve in the body after their function is complete, potentially eliminating the need for surgical removal and reducing healthcare costs. The device’s durability and performance under mechanical stress also open possibilities for disposable wearables, health monitors, and temporary military

Researchers in China have developed a novel recycling method called tribocatalysis that recovers valuable lithium and cobalt from dead lithium-ion batteries without generating toxic emissions or waste. This technique uses friction between surfaces combined with a weak acid to extract metal ions from the battery cathode. Unlike traditional recycling methods—pyrometallurgy, which involves high-temperature burning and releases harmful gases, and hydrometallurgy, which uses strong chemicals and produces toxic byproducts—tribocatalysis operates at low temperatures without harsh chemicals, making it safer, cheaper, and more environmentally friendly. The research, led by Professor Changzheng Hu at Guilin University of Technology and published in the Journal of Advanced Ceramics in June 2025, demonstrated through computer modeling and experiments that tribocatalysis efficiently recycles battery materials while reducing pollution and waste.

Caltech researchers have developed an innovative system that converts carbon dioxide (CO₂) from the air into durable, industrial-grade plastics using only electricity and chemistry. This breakthrough mimics natural photosynthesis but employs machines instead of plants, utilizing renewable electricity to first transform CO₂ into simple building blocks such as ethylene and carbon monoxide. These compounds are then fed into a second catalytic loop where they are converted into polyketones—high-strength plastics valued for their durability and thermal stability, commonly used in adhesives, automotive parts, sports equipment, and industrial piping. Unlike previous methods relying on fossil-derived ethylene, this process uses sustainably sourced CO₂, water, and electricity, potentially reducing emissions and dependence on petroleum-based feedstocks. The system operates via two separate loops optimized for different reaction conditions. The first loop uses gas diffusion electrode cells with copper-coated hydrophobic polymers to electrochemically reduce CO₂ into ethylene and carbon monoxide at relatively high concentrations (11% and 14%, respectively). These gases

Researchers at Flinders University, led by Professor Justin Chalker, have developed an innovative, toxin-free method to extract high-purity gold from ore and electronic waste. This new approach uses a low-cost, environmentally benign compound called trichloroisocyanuric acid—commonly used in water treatment—that, when activated by saltwater, dissolves gold effectively. The dissolved gold is then selectively captured by a specially designed sulfur-rich polymer, which is synthesized using a sustainable UV light-initiated process. Importantly, the polymer can be recycled after gold recovery, enhancing the method’s environmental credentials and reducing waste. This technique addresses the significant environmental and health hazards posed by traditional gold extraction methods that rely on toxic chemicals like cyanide and mercury. By providing a safer alternative, especially for small-scale mining operations that often use mercury, the new method has the potential to reduce mercury pollution globally. Additionally, it offers a promising solution to the growing challenge of electronic waste, which contains valuable metals but

The National Renewable Energy Laboratory (NREL) has developed a novel, scalable, and cost-effective method to recycle all components of carbon fiber composites (CFCs), materials widely used in high-value products like aircraft, bicycles, and automobiles. CFCs consist of carbon fibers embedded in epoxy-amine resins, which are strong, lightweight, and expensive, but difficult to recycle due to the chemically interlocked and complex nature of the resin. Traditional recycling methods have been limited by the inability to dissolve or break down these resins without degrading the valuable fibers or wasting the resin’s chemical components. NREL’s breakthrough involves using hot acetic acid—essentially vinegar—to cleave the key bonds in the epoxy resins, solubilizing the polymer networks while preserving the chemical building blocks for reuse. This method was optimized to handle diverse resin formulations from various industries and was shown to recover carbon fibers without compromising their strength. In a demonstration, recycled fibers extracted from a scrap mountain-bike frame were used to

Researchers led by Dr. Chi Zhou at the University at Buffalo have developed a sustainable thermal insulation material by 3D-printing fibers derived from wheat straw, an agricultural byproduct typically burned after harvest. Wheat straw’s natural fibrous and porous structure provides effective thermal insulation, high mechanical strength, and enhanced flame retardancy compared to other organic materials. The process involves pulping wheat straw into a slurry, drying it into a thick ink, and cross-linking the fibers with an organic binder to ensure material integrity before 3D printing. This innovation offers a renewable, biodegradable alternative to conventional insulation materials like glass and rock wool, which rely heavily on fossil fuels and contribute to greenhouse gas emissions. To address the slow printing speed of early methods, Zhou’s team redesigned the 3D printer with a slot-die nozzle and multiple nozzles for faster, more uniform material deposition, making the process scalable for industrial production.

Researchers at the Paul Scherrer Institute (PSI) have developed an AI-driven approach to design low-carbon cement recipes up to 1,000 times faster than traditional methods. Cement production is a major source of CO₂ emissions, primarily due to the chemical release of CO₂ from limestone during clinker formation. To address this, the PSI team, led by mathematician Romana Boiger, combined thermodynamic modeling software (GEMS) with experimental data to train a neural network that rapidly predicts the mineral composition and mechanical properties of various cement formulations. This AI model enables quick simulation and optimization of cement recipes that reduce carbon emissions while maintaining strength and quality. Beyond speeding up calculations, the researchers employed genetic algorithms to identify optimal cement compositions that balance CO₂ reduction with practical production feasibility. While these AI-designed formulations show promise, extensive laboratory testing and validation remain necessary before widespread adoption. This study serves as a proof of concept, demonstrating that AI can revolutionize the search for sustainable building materials by efficiently navigating complex chemical

The black, window-sized panel, made from a water-absorbent hydrogel enclosed in a glass chamber with a cooling polymer coating, exploits natural temperature fluctuations between night and day to absorb and then release water vapor. Tested in California’s Death Valley, one of the driest places on Earth, the prototype successfully extracted up to 160 milliliters of water daily even at low humidity levels (around 21%), demonstrating its effectiveness in arid environments. The hydrogel’s unique composition, stabilized with glycerol to prevent salt leakage, ensures the collected water remains safe to drink without the need for additional filtration. Its dome-shaped, bubble wrap–like surface design increases absorption efficiency by maximizing surface area. Unlike previous technologies that depend on electricity, batteries, or solar panels, this device operates autonomously, making it particularly suitable for resource-limited

Researchers at the University of Michigan, led by chemist Charles McCrory, have developed a novel method to capture carbon dioxide (CO₂) from the air and convert it into metal oxalates, stable solid compounds that can serve as precursors for cement production. This approach aims to transform CO₂, typically viewed as a waste product, into valuable building materials, potentially reducing the carbon footprint of construction. The work is part of efforts by the Center for Closing the Carbon Cycle (4C), funded by the U.S. Department of Energy, which focuses on converting captured carbon into useful fuels and industrial products. The team’s innovation centers on using trace amounts of lead as a catalyst to convert CO₂ into metal oxalates via electrochemical reactions. By employing specially designed polymers, they reduced the lead catalyst to parts per billion—levels comparable to natural impurities—addressing previous environmental and health concerns associated with higher lead usage. In the process, CO₂ is electrochemically transformed into oxalate ions, which then combine with metal ions released from an electrode to form solid metal oxalates. These solids are stable and do not revert to CO₂ under normal conditions, making them promising for cleaner cement production. While electrolysis of CO₂ is already being scaled up industrially, the researchers note that further work is needed to scale the metal oxalate production step, but they remain optimistic about its feasibility. This breakthrough offers a potential pathway to reduce the environmental impact of traditional Portland cement manufacturing, which is energy-intensive and a major source of global carbon emissions. By turning pollution into building blocks, the research opens new avenues for sustainable construction materials and carbon capture utilization. The study detailing these findings was published in the journal Advanced Energy.

The article highlights the urgent call by the United Nations Environment Program (UNEP) for global action to #BeatPlasticPollution, the theme of World Environment Day 2025. It emphasizes the critical importance of addressing the full lifecycle of plastics—from production to disposal—rather than relying solely on recycling. With over 460 million tons of plastic produced annually, plastics and microplastics have become pervasive pollutants, infiltrating terrestrial and marine ecosystems, soils, the atmosphere, and even human bodies, including lungs, blood, and fetuses. This widespread contamination poses serious threats to human health, planetary ecosystems, and economic stability. The article also notes that plastics contribute significantly to carbon emissions and are filling oceans, harming marine life and coastal communities. South Korea, the 2025 World Environment Day host, is identified as the fourth largest producer of plastic polymers globally, underscoring the challenge of plastic pollution even among environmentally engaged nations. The article draws attention to the prevalence of polyethylene terephthalate (PET) plastics, which constitute about 50% of microplastics in wastewater and 12% of global solid waste, highlighting ongoing research into biodegradation methods. Looking ahead, plastic production is projected to triple by 2060 unless decisive global measures are taken. A key upcoming event is the August 2025 vote in Geneva on a global plastics treaty aimed at banning certain plastics, though progress faces resistance from petrochemical-producing countries. Advocates stress the need to “turn off the plastics tap” and implement systemic changes to reduce plastic pollution worldwide.
