Researchers are using machine learning to analyze satellite radar data to detect icebergs in the Southern Ocean around Antarctica as a way to better understand their life cycle and environmental impact.

To drive down the cost of biodiesel, researchers have developed an eco-friendly way of extracting triacetin, a combustion-enhancing additive, from an abundant waste source, cigarette butts, both reducing waste and providing a sustainable use for it.

Researchers have created a floating, solar-powered device that converts contaminated water or seawater into clean hydrogen fuel and drinking water. Because it works with any open water source, it could be used in resource-limited or remote places.

While the use of recycled plastics is normally considered a noble endeavor, a new study says it's time to think twice. In an analysis of the material from more than 10 different countries, hundreds of potentially harmful chemicals were uncovered.

Disposable diapers are a huge source of global waste, largely because they're difficult to recycle. A new process, however, could salvage the "superabsorber" polymer utilized in the liners of those diapers – and yes, even if they're soiled.

Checking for pollutants in the environment via soil sampling and other traditional methods can be a laborious process, but what alternatives are there? Well, scientists have now engineered a plant to turn red when exposed to specific toxic chemicals.

Purifying polluted soil can be a difficult process, often requiring the soil to be dug up and transported to an offsite remediation facility. Now, however, scientists have developed an eco-friendly method of treating it where it lays – by zapping it.

Salmon are very much a cold-water fish, so they can get quite stressed when swimming up increasingly warm rivers to spawn. A new study shows that by installing "cooling stations" in those rivers, we could help the threatened fish make the trip.

According to some estimates, the generation of the heat used to produce traditional portland cement is responsible for 5% to 8% of all human-made CO2 emissions. A new substance known as C-Crete, however, is claimed to be a much greener alternative.

So-called "bonded leather" is really just leather fibers mixed with eco-unfriendly polyurethane or PVC. reProLeather, on the other hand, converts leather waste into what is claimed to be a recyclable, biodegradable, new-leather-like material.

Each day we’re learning of new, devastating impacts of climate change, and what's now brewing has researchers sounding the alarm on the future of European beer, thanks to a steady decline in the quality and quantity of high-quality hops from the region.

With a continuing hot streak felt across the Earth, 2023 is now on track to be the warmest year on record. And September was no exception; in fact, it broke existing records by a large margin, according to the World Meteorological Organization.

It was just last month that we heard how waste coffee grounds could be utilized to boost the strength of concrete. Well, new research shows that such otherwise-unwanted grounds could also be used to 3D-print plant pots, single-use cups and more.

Although lithium can be found in hard mineral ores, it's more often extracted from very salty (aka briny) groundwater. The latter task could soon be much quicker and eco-friendlier, thanks to a new string-based extraction technique.

A new study has found that we’re doing something right when it comes to air pollution. An analysis of global data has found that exposure to fine particulate matter, a leading environmental health risk, has fallen.
