Researchers Turn Algae Into a Material as Hard as Steel

Algae in a pond may look flimsy. But scientists are using algae to develop industrial-strength material that's as hard as steel but only a fraction of the weight.




Thomas Brück of the Technical University of Munich, Germany, and his team developed a process that uses algae oil to create carbon fibers. They're strong, lightweight materials that can be used in cars, airplanes and buildings.

Making these carbon fibers uses far less energy and produces far less carbon pollution than making concrete or steel. But that's not its only climate benefit.

Algae absorb CO2 as they grow, so when algae oil is used as a raw material for carbon fibers, the CO2 gets locked inside.

Years later, when those carbon fibers need to be disposed of, they can be ground up and permanently stored underground.

"So you have this very new advanced material where you can actually store atmospheric carbon indefinitely," Brück says.

He says scaling up will require big investments in algae cultivation. But once that's in place, this new technology could create strong industrial materials that also benefit the climate.

President Trump's claim that the U.S. has the cleanest air and water in the world has been widely refuted by statistics showing harmful levels of pollution. Now, a new biannual ranking released by researchers at Yale and Columbia finds that the U.S. is nowhere near the top in environmental performance, according to The Guardian.

New Jersey has invested in the future health of the planet by making sure the next generation of adults knows how human activity has had a deleterious effect on the planet. The state will be the first in the nation to make the climate crisis as part of its curriculum for all students, from kindergarten all the way to 12th grade, as NorthJersey.com reported.

The SARS-CoV-2 virus is novel, but pandemic threats to indigenous peoples are anything but new. Diseases like measles, smallpox and the Spanish flu have decimated Native American communities ever since the arrival of the first European colonizers.

The ocean is our lifeline - we rely on it for the food we eat, the air we breathe, as well as for millions for jobs worldwide.

As we continue to grapple with the issues of overfishing, plastic pollution, and climate change, there exists an opportunity to address these existential threats with new innovations, many of which unidentified or insufficiently supported.

Pipeline giant Kinder Morgan is cutting a 400-mile line across the middle of Texas, digging up vast swaths of private land for its planned Permian Highway Pipeline. The project is ceaseless, continuing through the coronavirus pandemic. Landowner Heath Frantzen said that dozens of workers have showed up to his ranch in Fredericksburg, even as public health officials urged people to stay at home.
