NewsScientists break down shoe foam by genetically tweaking a microbe found in compost
Researchers have developed a new kind of enzyme based on a bacterium found in compost that can degrade the polyurethane material in shoe foams. The results could one day help recycle plastic waste from shoes, mattresses, kitchen sponges, and more.

NewsDairy waste to fuel: New process unlocks potential of 95,000 tonnes of salty whey
A company that helped design how astronauts grow and recycle food in space is now applying that thinking to the critical problem of dairy waste here on Earth. Scientists turned salty whey, a high-volume by-product from cheese production, into bioethanol.

NewsPairing biofertilizers with biochar turns farm and city waste into climate-smart soil solutions
A new review makes the case that organic waste from farms, cities and industries could become a resource for healthier soil and more resilient farming — if two waste-derived soil treatments, microbial biofertilizers and biochar, are used together rather than separately.

NewsCo-digestion of waste and wastewater from biomanufacturing for energy recovery
Researchers have developed the Anaerobic Baffled Continuous Stirring (ABCS) reactor, a device capable of simultaneously treating solid waste and wastewater from biomanufacturing processes while recovering methane for energy self-sufficiency.

NewsReview explores the presence, fate, and effects of pharmaceutical compounds in soil and air
Pharmaceutical contamination in soil and air has become a critical environmental concern due to its widespread sources, complex behavior, and long-lasting ecological impacts.

NewsWastewater may offer an early warning of pertussis outbreaks
Researchers found that pertussis-associated DNA in wastewater rose weeks before reported whooping cough cases, pointing to a new way to complement clinical surveillance.

NewsHerbal residue reshapes gut microbes and lipid metabolism in broilers
A research team found that dietary Radix isatidis herbal residue, a traditional Chinese medicine by-product, may improve growth, mucosal immunity, gut microbiota, and lipid metabolism in broilers.

NewsGenome-scale model-guided microbial engineering converts agricultural waste into biodegradable bioplastics
Researchers develop a genome-scale model-guided microbial engineering platform that converts kimchi industry waste into biodegradable bioplastics.

NewsCorn stalks. It’s what’s for dinner … If you’re a microbe
Engineers have developed a strain of a common bacterial species, Pseudomonas putida, that can feed exclusively on the three major sugars present in corn stalks, with broader implications for the future of biomanufacturing.

NewsBiochar made from brewery waste could help trap harmful bacteria in sandy filtration systems
Researchers have found that biochar made from a common brewery byproduct can substantially improve the ability of sand to retain Escherichia coli, pointing to a potential new use for brewing waste in water filtration and groundwater protection.

NewsRecycling food waste would bring huge benefits, but microplastics a challenge
A first nationwide look shows diversion of U.S. food waste from landfills could reduce related climate impacts by 89% and nutrient pollution by 50%, researchers say.
-
NewsLow carbon dioxide levels improve microbial production of biodegradable plastic
In an innovative gas fermentation process, reducing concentration of carbon dioxide was found to significantly improve microbial production of the biodegradable plastic, poly[(R)-3-hydroxybutyrate]. The study provides a promising strategy for sustainable carbon recycling and efficient CO2 utilization.

NewsFood waste treatment can boost renewable energy, but a hidden brown byproduct may be holding it back
Researchers have identified a key chemical obstacle in turning food waste into renewable methane, offering a new semi-quantitative way to track melanoidins and showing that higher doses can severely damage the microbial system.

NewsArctic microplastics: A ticking time bomb for climate feedback loops
A new study systematically maps the major transport pathways—atmospheric, oceanic, and local—and details how microplastics infiltrate Arctic food webs and interact with physical and biogeochemical processes that govern regional climate.
-
NewsWasted pumpkin peel can keep your food fresh
Researchers have turned agricultural by-products into a biodegradable food packaging material, offering a potential approach to both food loss and plastic pollution.

NewsSoil bacteria reveal hidden arsenic stress in brick kilns
Researchers collected soils from a shut-down brick kiln area. As arsenic levels increased, bacterial richness and diversity declined, while arsenic-tolerant groups became more abundant. The study also found that bacteria strengthened stress-response pathways and upregulated arsenic-resistance genes.

NewsTracking melanoidins to improve food-waste biogas recovery
Higher pretreatment temperatures in food-waste biogas recovery can promote Maillard reactions, generating melanoidins. A study shows that melanoidins increase with hydrothermal temperature and inhibit methane production by disrupting methanogenic microbial communities.
-
NewsMicrobes frozen in ancient rubbish heaps help reconstruct ancient Greenlanders’ farms, seal hunts, and toilets
The microbiome of ancient middens in Greenland sheds new light on the daily life of Paleo-Inuit and old Norse communities. Researchers say the middens in the cold Arctic acted like long-term natural experiments, with human- and animal-associated bacterial signals remaining detectable many centuries later.
