Plump, wiggly slugs may look innocuous, but they can wreak serious havoc on a carefully-curated garden, even causing total crop failure.

"The unfortunate part is that in order to be able to support an entire industrial base, you've got to have that whole supply chain node-matched in terms of capacity," Zach Detweiler, co-founder and CEO of Radify Metals, explained. He emphasized the importance of addressing the overlooked node that converts metal oxides into pure metals, which he refers to as the 'missing middle.'

"We didn't know what we had," Michele Stansfield, co-founder and CEO of Cauldron Ferm, told TechCrunch. But eventually, Stansfield realized they had more than initially thought.

Perforated metal has long been valued for its strength, versatility, and clean visual appeal. Created by punching patterns of holes into metal sheets, it offers a practical balance between airflow, light control, and structural support. Across industries such as architecture, construction, mining, and interior design, perforated metal has become a go-to material for projects that require both function and style.

Most water filter pitchers are made of BPA-free plastic. But as new research shows that bottled-water drinkers ingest tens of thousands of excess microplastic particles, wellness lovers have begun to look askance at water filters that are themselves made of plastic.

Korea Zinc, which it described as one of the world's largest smelters, is in talks with major US technology firms to recycle data center waste and extract rare earth. The move comes almost one year to the day after China announced immediate export controls on seven more rare earth elements critical to enterprise IT hardware manufacturing.

Environmental monitoring has traditionally relied on snapshots of exposure from a water sample collected on a single day, a blood sample drawn at one point in time, or soil tested from a specific location. But exposure unfolds gradually as people move through different environments and come into contact with air, dust, and surfaces throughout the day.

Crude oil is a complex mixture of hydrocarbons - molecules made mainly of carbon and hydrogen. Refineries and chemical plants separate and transform these molecules into smaller chemical building blocks known as petrochemicals. Some of the most important petrochemical building blocks include chemicals such as ethylene, propylene and benzene.

It's a little-known fact that Columbia University, in Manhattan, was home to the first mining school in America-the School of Mines-founded in 1864. For the past three decades, the university's program has been mothballed. Parts of its curriculum were subsumed into the more fashionable subjects of earth and environmental engineering. But next fall, Columbia University will offer a bachelor of science degree in mining engineering once again.

Never place batteries of any type in your curbside recycling bin. Batteries can damage recycling equipment and, if lithium batteries are mixed in, cause fires. Always use designated battery collection programs.

The Army recently published a Request For Information on Autonomous Decontamination Systems (ADS) to see what might be out there in the existing commercial market to help its Chemical, Biological, Radiological and Nuclear (CBRN) troops more easily clean up contaminated vehicles, infrastructure, and terrain. "ADS will reduce manpower and optimize resources required for decontamination operations while mitigating the risk of exposure of warfighters to Chemical and Biological Warfare Agents through robotic means," the Army said in its RFI.

According to the UN's Global E-waste Monitor 2024, a record 62 million metric tons of electronic waste was generated worldwide in 2022, an 82% increase since 2010. E-waste is projected to reach 82 million metric tons by 2030. In the U.S. alone, roughly 8 million tons of e-waste is discarded each year.

The team, from the Chinese Academy of Sciences and Beijing Institute of Technology, recently published their findings in Nature Communications. According to their research, the process not only avoids conventional leaching chemicals and extreme heat to extract lithium from old batteries, but it also uses carbon dioxide in what the authors call a sequestration step, and turns other battery transition metals into new catalysts - with CO₂-rich water doing most of the chemical work.

Amazon's data centers will reportedly utilize copper from a mine in Arizona that's leaching metal from ores using microorganisms, the Wall Street Journal reports. Amazon Web Services will be the first customer for Nuton Technologies, which developed the "bioleaching" technology. AWS will also be providing "cloud-based data and analytics support," helping to optimize Nuton's mining process. Nuton's bioleaching method uses naturally-occurring microorganisms to extract copper from low-grade ore that would otherwise be too expensive to mine,

Clean Harbors just locked in a $110 million contract for PFAS water filtration at Joint Base Pearl Harbor-Hickam. This isn't just another project win. It's validation of the company's end-to-end PFAS solution: lab analytics, water filtration, site remediation, and most critically, high-temperature incineration disposal.

Lithium-ion (Li-ion) batteries are found in many devices we use every day, like smartphones, laptops, tablets, wireless earbuds, power tools, e-bikes, and electric vehicles. By 2023, there were more than 40 million electric vehicles on the road worldwide, and billions of portable electronics used Li-ion cells. These batteries are valuable for recycling, but they can be dangerous if not disposed of correctly.

Many human activities - from improper disposal of waste to the degradation of car tyres - release small plastic particles, which have infiltrated the atmosphere, oceans and other ecosystems. These include nanoplastics - particles measuring less than 1 micrometre across - and microplastics, which range from 1 micrometre to around 5 millimetres. They've entered our bodies and brains, and scientists are still working to understand their effects on people's health.

According to research by the World Economic Forum and United Nations Development Programme, the circular economy could unlock $4.5 trillion in new global value by 2030, and investors are racing to capture part of that opportunity. Meet Elizabeth Blankenship-Singh, Director of Innovation at Overlay Capital, an Atlanta-based alternative investment firm whose Waste and Materials Fund is backing both early-stage materials innovators and later-stage recycling operations with established infrastructure.

A worker sweeps the track at the National Stadium during the 2008 Beijing Olympics, which was disrupted by heavy rain. Photograph: AFP/Getty Images The secret weapon is a network of capillary-like tubes that weave through the Bird's Nest's outer lattice, which are specifically designed to siphon away rainfall. The pipes channel rainwater into one of three underwater storage tanks, where it is filtered and prepared for recycling within the building.
