Winter weather poses significant challenges for road maintenance, with snow and ice accumulation causing hazards and necessitating costly clearing operations. However, researchers at Drexel University have developed a groundbreaking solution: self-heating concrete integrated with a phase-change material. This innovation promises to melt snow and ice for extended periods without the need for salt or manual intervention, offering a sustainable and efficient alternative for road management.

The integration of a phase-change material, specifically paraffin, into concrete slabs enables them to release heat when temperatures drop, effectively melting snow and ice. By maintaining a surface temperature above freezing, the self-heating concrete reduces the need for plowing and salting, mitigating the associated costs and environmental impacts.

In a wooded area along the Hudson River, a unique structure is slowly taking shape. This building, however, is not conventional; it’s designed to house not just humans but also animals and plants. What sets it apart is that it’s constructed from, or rather, by growing trees. This groundbreaking project is the brainchild of Terreform One, a non-profit organization focusing on art, architecture, and urban design, led by architect Mitchell Joachim.

The concept of this tree-integrated building had its roots around 2002 when Habitat for Humanity initiated a design competition seeking fresh approaches to suburban housing. Joachim, pursuing a Ph.D. in architecture at MIT, collaborated with researchers Lara Greden and Javier Arbona to explore ecological processes for large-scale housing construction. Their goal was to leverage computing, fabrication systems, and ecological principles to guide nature in creating usable structures.

In a groundbreaking development, researchers have unveiled an economically viable method to reduce the environmental impact of both the steel and aluminum industries. By utilizing hydrogen to melt down the toxic red mud, a byproduct of aluminum production, scientists from the Max-Planck-Institut für Eisenforschung in Germany have devised a process that yields green steel in just 10 minutes.

The aluminum industry annually generates approximately 198 million tons (180 million tonnes) of bauxite residue, known as red mud, which poses environmental challenges due to its high alkalinity and rich content of toxic heavy metals. Traditionally, red mud is disposed of in large landfills, incurring high processing costs. Simultaneously, the steel industry contributes significantly to global carbon dioxide emissions, accounting for 8%. Despite these environmental concerns, the demand for steel and aluminum is expected to surge by up to 60% by 2050.

The state of California has recently passed a new regulation that will ban the sale of diesel-powered trucks starting in 2036, in an effort to promote cleaner air and reduce carbon emissions. The new rule is part of the state’s Advanced Clean Fleets program, which aims to make California’s entire trucking industry zero emissions by 2045. The California Air Resources Board (CARB) voted in favor of the rule last Friday, but it still awaits approval from the Environmental Protection Agency (EPA) to take effect.

While the ban on diesel trucks is a step towards a cleaner future, not all zero-emission trucks will be battery-powered. Fuel cell trucks that generate electricity through the combination of hydrogen stored in tanks with atmospheric oxygen also qualify under the rule. The only byproduct of fuel cell trucks is water vapor, making them a cleaner alternative to diesel-powered trucks.

Section of the Garbage Patch in 2019.

By CARLY CASSELLA

Our oceans are swirling concoctions of waste that scientists have for years reported are fed by an influx of pollution from both the land and the sea.

But working out what rubbish winds up in the Great Pacific Garbage Patch in the North Pacific, where it comes from, and who is responsible is an ongoing challenge. Now a new study further implicates the global fishing industry in the mix.

“Here we show that most floating plastics in the North Pacific subtropical gyre can be traced back to five industrialized fishing nations,” data scientist Laurent Lebreton and colleagues write.

When analyzing 573 kilograms of (dry) hard plastic debris collected by Lebreton and The Ocean Cleanup organization in 2019, the researchers found more than a quarter of the fragments were from ‘abandoned, lost or otherwise discarded fishing gear’ (aka ALDFG) – and that’s not including discarded fishing nets and ropes.

This waste category includes items like oyster spacers, eel traps, and lobster and fish tags, as well as plastic floats and buoys.

Another third of the debris was unidentifiable.

When the authors used computer models to simulate how their samples ended up in the patch, they found that a plastic fragment was 10 times more likely to originate from fishing activities than land-based ones.
