In a new study published in the journal Chaos, scientists Larry Pratt and Irina Rypina from the Woods Hole Oceanographic Institution in Massachusetts turned to 3D modeling to understand how microplastics move in chaotic environments like the ocean. Because oceans are so vast, gathering sampling data isn’t an option. So the researchers delved deep into modeling how tiny particles move in a 3D fluid, and found that microplastics tend to eventually form an “idealized eddy” (circular current) that closely resembles a kind of closed-loop tornado of ecological destruction.

The idea seems futuristic: At ETH Zurich, various disciplines are working together to combine conventional materials with bacteria, algae and fungi. The common goal: to create living materials that acquire useful properties thanks to the metabolism of microorganisms – "such as the ability to bind CO₂ from the air by means of photosynthesis," says Mark Tibbitt, Professor of Macromolecular Engineering at ETH Zurich.

An interdisciplinary research team led by Tibbitt has now turned this vision into reality: it has stably incorporated photosynthetic bacteria – known as cyanobacteria – into a printable gel and developed a material that is alive, grows and actively removes carbon from the air. The researchers recently presented their "photosynthetic living material" in a study in the journal Nature Communications.

Arbikie Distillery has partnered with Dr Dongyang Sun, Edinburgh Napier University, and Dr. Wenbin Zhou, University of Dundee, to use mycelium, the root structure of fungi, and distillery by-products like spent grain to create durable, lightweight packaging. The material created is impact-resistant, fire-retardant, and fully compostable, offering an eco-friendly alternative to plastic. Over the next 10 months, the project team will focus on proof of concept, testing the material, and the design. Funded by Scotland Beyond Net Zero – a coalition of leading climate and sustainability experts from Scotland's universities – this project is one of 11 new research collaborations aimed at accelerating Scotland's transition to net zero. Each project involves cross-sector collaborations to address sustainability challenges in energy, finance, food, the built environment, natural systems, and transport.

Advocates are particularly concerned over the use by datacenters of PFAS gas, or f-gas, which can be potent greenhouse gases, and may mean datacenters’ climate impact is worse than previously thought. Other f-gases turn into a type of dangerous compound that is rapidly accumulating across the globe. Two kinds of cooling systems are used to prevent the semiconductors and other electronic equipment stored in datacenters from overheating. Water cooling systems require huge volumes of water, and chemicals like nitrates, disinfectants, azoles and other compounds are potentially added and discharged in the environment. Many centers are now switching to a “two phase” system that uses f-gas as a refrigerant coolant that is run through copper tubing. In this scenario, f-gas is not intentionally released during use, though there may be leaks, and it must be disposed of at the end of its life.

A team of McGill University researchers has developed a cost-effective, high-throughput technology for detecting nanoplastics and microplastics in the environment. These particles are pervasive, posing health and environmental risks, yet detecting them at the nanoscale has been difficult. The 3D-printed HoLDI-MS test platform overcomes the limitations of traditional mass spectrometry by enabling direct analysis of samples without requiring complex sample preparation. The researchers say it also will work for detection of waterborne plastic particles. HoLDI-MS stands for hollow-laser desorption/ionization mass spectrometry. According to Chemistry Professor Parisa Ariya, who led the study published last month in Nature’s Communications Chemistry, “It requires little energy, is recyclable and costs only a few dollars per sample."

A study describes a new method of recycling silicone waste (caulk, sealants, gels, adhesives, cosmetics, etc.). It has the potential to significantly reduce the sector's environmental impacts. This is the first universal recycling process that brings any type of used silicone material back to an earlier state in its life cycle where each molecule has only one silicon atom. And there is no need for the raw materials currently used to design new silicones. Moreover, since it is chemical and not mechanical recycling, the reuse of the material can be carried out infinitely.

More than half of the 7.5 million bales of cotton produced annually in the U.S. will be used in clothing manufacturing. The finishing techniques used to make cotton fabric smooth, water-repellant and resistant to wrinkling can be detrimental to the environment and the wearer.

Most remediation of per- and polyfluoroalkyl substances (PFAS) involves adsorbing and trapping them, but certain microbes can actually break apart the strong chemical bonds that allow these chemicals to persist for so long in the environment. Now, a University at Buffalo-led team has identified a strain of bacteria that can break down and transform at least three types of PFAS, and, perhaps even more crucially, some of the toxic byproducts of the bond-breaking process.

Pesticides banned years ago in the European Union are drifting through the skies and turning up in clouds above France, raising concerns about how long these toxins persist and how far they can travel, with potentially harmful global health impacts, according to a pathbreaking new study.  The research, published in Environmental Science & Technology, is the first to detect dozens of agricultural chemicals—including insecticides, herbicides, fungicides, and other substances—suspended in cloud water droplets. That means pesticides not only linger in the environment but also move through the atmosphere and fall back to Earth in rain or snow, sometimes at levels exceeding European safe drinking water limits, the research suggests.

Years of persistence and experimentation led to a biodegradable coffee pod that improves brewing performance. Inspired by baristas tamping down grounds for espresso, the Keurig team sought to compact the coffee tightly enough to maintain its patty shape without a container. Along the way, the new format also yielded a stronger brew. However, the team realized those naked coffee pods would not survive distribution. They tried beeswax before landing on an algae-based coating that kept the pods intact. Their prototyping advanced in 2021 in the company lab with a small pilot line of coffee pods. The team used a hand crank to encapsulate roasted and ground coffee in a layer of alginate. This coating was found to tolerate pressure levels up to approximately 200 pounds per square inch, meaning the pods could be used to brew espresso. Today, about 200 consumers are beta-testing the pods, called K-Rounds, in their homes, providing daily data that helps with product refinement.

Tile drainage is a common practice used in agricultural fields to remove excess water, but it also transports harmful nutrients into water bodies, contributing to algal blooms that deprive aquatic life of oxygen. Woodchip bioreactors are an efficient way to reduce nitrogen pollution by treating the water as it exits the field. However, these denitrifying bioreactors may leach phosphorus from the woodchips into the environment.
