In a new project aimed at combating microplastic pollution, Louisiana Tech University welcomes Dr. Gaurav Pandey, a recipient of the prestigious Fulbright Fellowship, to the research team of Dr. David K. Mills, retired professor of biological sciences, and Dr. Rebecca Giorno-McConnell, professor of biological sciences. The team will develop innovative solutions to the global challenge of microplastics in soil and wastewater.

"Joining this research team at Louisiana Tech is an incredible opportunity to address one of the most persistent environmental challenges of our time-microplastic pollution," Pandey said. "The pervasive and enduring presence of microplastics in our environment is a challenge that demands innovative and sustainable solutions."

Plastic particles can take centuries to decompose. Microplastics pose a significant threat to wildlife and human health, with evidence linking them to adverse effects on fish and potential health concerns for humans as they enter food and water supplies.

"The challenge with plastic pieces and microplastics in our soil and water is their non-biodegradability," Mills said. "As a synthetic material, natural ecosystems cannot quickly process plastic. It is estimated that plastics can persist for 450 to 600 years, increasing the potential for more harmful effects and underscoring the need for immediate and sustainable solutions."

Microplastics, typically smaller than 5 millimeters, accumulate rapidly in the environment. Plastic products dominate global markets, but only about 9 percent of plastic waste is recycled annually, while the remainder often enters agricultural soils, waterways, and ecosystems.

The research team aims to address this issue by using natural materials and light-powered technology. This combination of methods is anticipated to achieve more effective and sustainable degradation of microplastics, marking an innovative approach to managing plastic waste.

"Our goal is to develop advanced methods that not only effectively break down these persistent pollutants but also ensure that our approaches are environmentally friendly and scalable for real-world applications," Pandey added. "Being part of a team led by such esteemed scientists who are equally dedicated to tackling this critical issue is both inspiring and fulfilling. I am passionate about leveraging our collective expertise to create meaningful and lasting impacts, helping to protect ecosystems and improve the health of our planet for future generations."

"I am delighted to host Dr. Pandey at Louisiana Tech," said Giorno-McConnell. "Biodegradation of microplastics with bacteria is an environmentally friendly approach for eliminating this plastic waste but is very slow and therefore ineffective for a global solution. Dr. Pandey's approach of immobilizing bacterial enzymes to nanoparticles could address these limitations."

The project stands as a testament to Louisiana Tech's commitment to addressing global environmental challenges through cutting-edge research and collaboration.
