University of Central Florida Researchers Unveil Breakthrough in Greenhouse Gas Recycling

UCF researchers Richard Blair (left) and Laurene Tetard (right) are long-time collaborators and have developed new methods to produce energy and materials from the harmful greenhouse gas, methane.

In a significant step toward sustainable energy, researchers from the University of Central Florida (UCF) have innovated methods to convert the potent greenhouse gas, methane, into green energy and advanced materials.

Methane, with an impact 28 times greater than carbon dioxide over a century, is a notable contributor to global warming. Its emissions predominantly arise from energy sectors, agriculture, and landfills. Now, UCF’s groundbreaking methods might turn this environmental challenge into an opportunity, as they utilize methane for producing green energy and crafting high-performance materials for smart devices, solar cells, and biotech applications.

Behind these inventions are UFC researchers, nanotechnologist Laurene Tetard and catalysis specialist Richard Blair. Tetard is an associate professor and associate chair of UCF’s Department of Physics. He is also a researcher with the NanoScience Technology Center. Blair is a research professor at UCF’s Florida Space Institute. The two have been collaborating on research projects for the past decade.

Their pioneering technique produces hydrogen from methane without carbon gas emission. Utilizing visible light sources, like lasers or solar energy, and defect-engineered boron-rich photocatalysts, the process emphasizes the advanced potential of nanoscale materials.

Blair highlights the dual benefits: You get green hydrogen, and you remove — not really sequester — methane. You’re processing methane into just hydrogen and pure carbon that can be used for things like batteries.” Traditional methods, Blair notes, produce CO2 along with hydrogen. Their innovation not only tackles methane emissions but also transforms it into valuable hydrogen and carbon. Market applications include possible large-scale hydrogen production in solar farms and methane capture and conversion.

“Our process takes a greenhouse gas, methane and converts it into something that’s not a greenhouse gas and two things that are valuable products, hydrogen and carbon. And we’ve removed methane from the cycle.”

Additionally, this technology from Tetard and Blair offers the ability to manufacture carbon structures at nano and micro scales using light and a defect-engineered photocatalyst. Envisioning it as a “carbon 3D printer,” Blair notes the dream is to make high-performance carbon materials from methane.

“It took a while to get some really exciting results,” Tetard says. “In the beginning, a lot of the characterization that we tried to do was not working the way we wanted. We sat down to discuss puzzling observations so many times.”

Countries lacking significant power sources could potentially benefit, requiring only methane and sunlight to leverage the innovation. As Blair summarizes, the process takes a greenhouse menace and turns it into precious, non-polluting commodities.

These Scientists Are Making Antibacterial Bandages Out Of Fruit Waste

  • Scientists at Nanyang Technological University in Singapore are transforming discarded durian husks into antibacterial gel bandages.

  • The process extracts cellulose powder from the fruit’s husks after they are sliced and freeze-dried.

  • The husks, which make up more than half of the composition of durians, are usually discarded and incinerated, contributing to environmental waste.

Scientists at Nanyang Technological University (NTU) in Singapore are tackling food waste by turning discarded durian husks into antibacterial gel bandages.

The process extracts cellulose powder from the fruit’s husks after they are sliced and freeze-dried, then mixes it with glycerol. This mixture becomes soft hydrogel, which is then cut into bandage strips.

“In Singapore, we consume about 12 million durians a year, so besides the flesh, we can’t do much about the husk and the seeds and this cause environmental pollution,” said Professor William Chen, director of the food science and technology programme at NTU. The fruit’s husks, which make up more than half of the composition of durians, are usually discarded and incinerated, contributing to environmental waste.

Chen added that the technology can also turn other food waste, such as soy beans and spent grains, into hydrogel, helping limit the country’s food waste.

Compared to conventional bandages, the organo-hydrogel bandages are also able to keep wound areas cooler and moist, which can help accelerate healing.

The researchers say using waste materials and yeast for the antimicrobial bandages is more cost effective than the production of conventional bandages, whose antimicrobial properties come from more expensive metallic compounds like silver or copper ions.

A durian wholeseller, Tan Eng Chuan, said he goes through at least 30 crates of durians a day during durian season – as much as 1,800 kg. Being able to use the parts of the fruit that are ordinarily discarded, he said, was an innovation that would make enjoying it “more sustainable”.

TED & Future Stewards Host Countdown Global Launch

TED and Future Stewards Host Global Countdown Event Mobilizing Millions to Halve Greenhouse Gas Emissions by 2030 in the Race to a Zero-Carbon World

Countdown, a global initiative to champion and accelerate solutions to the climate crisis, launches today, Saturday, October 10, 2020 with a free five-hour live virtual event featuring leading thinkers and doers.

Countdown is one part of a broader series of actions and events this fall including the Bloomberg Green Festival, Climate Week NYC, and others, all with the collective objective of informing and activating millions in the lead-up to a successful UN Climate Change Conference in November 2021.

Speakers will touch on topics such as:

  • Climate science and the climate crisis: Where are we today?
  • Why climate justice matters
  • Putting climate back on the political and social agenda
  • What businesses can do—and are doing—to transform and transition
  • Rethinking our cities
  • Stepping up at work and at home
  • The path to a safer, cleaner, fairer future for people and the planet

A full agenda and speaker list can be found here.

The moment to act on climate change has been upon us for too long, and now is the time to unite all levels of society—business leaders, courageous political actors, scientists and individuals—to get to net-zero emissions before 2050.”

—Chris Anderson, Countdown founding partner and Head of TED

“Countdown brings together a powerful collaboration of partners from all sectors to act on climate change.”

—Lindsay Levin, Countdown founding partner and CEO of Leaders’
Quest

Countdown aims to answer five fundamental, interconnected questions that inform a blueprint for a better future:

  • ENERGY: How rapidly can we switch to 100% clean power?
  • TRANSPORT: How can we upgrade the way we move people and things?
  • MATERIALS: How can we re-imagine and re-make the stuff around us?
  • FOOD: How can we spark a worldwide shift to healthier food systems?
  • NATURE: How do we better protect and re-green the earth?

Countdown is asking companies and organizations to join the Race to Zero through Business Ambition for 1.5°C, which is a commitment to set science-based targets aligned with limiting global warming to 1.5°C, and through The Climate Pledge, which calls on signatories to be net zero carbon by 2040—a decade ahead of the Paris Agreement goal of 2050.

We can inspire others through action and example, because there is no hope without action.”

—17-year-old climate justice activist Xiye Bastida, a lead organizer of the Fridays for Future

Five years after the unanimous signing of the Paris Agreement, many countries, companies and citizens are doing what they can about the climate crisis. But this is not enough.”

—Christiana Figueres, former UN climate chief (2010-2016), now co-founder of Global
Optimism
