Thanks to an East Tennessee science powerhouse, recycling might become easier 

This is the first in a series about ORNL’s Technology Innovation Program 2023

OAK RIDGE — Researchers at Oak Ridge National Laboratory developed a catalyst they say can break down a range of plastics, including polyesters, polycarbonates, polyurethanes and polyamides through a low-energy green process. In lay terms, the process can recycle many plastic-based carpets, ropes, other textiles, bottles, mattresses, protective equipment, car components and other things that weren’t previously easy to recycle into valuable chemicals.

Tomoronori Saito, a researcher at ORNL’s chemical sciences division presented some results of research at ORNL on July 14 as part of a symposium highlighting commercially valuable work that takes place at one of the country’s main science laboratories. Saito and fellow researcher Arif Arifuzzaman showed off plastics in varying levels of disintegration using their catalyst. It was part of the lab’s Technology Innovation Program 2023, promoting the lab’s research for possible business partnerships.

Poignant plastic-waste art exhibit washes ashore at Tennessee Aquarium  

CHATTANOOGA — Visitors to the Tennessee Aquarium will see a dire warning in the guise of colorful art crafted from plastic debris at a unique exhibit beginning April 16.

Washed Ashore is an Oregon-based nonprofit organization dedicated to repurposing plastic waste through artists and sparking conservation conversations. The Tennessee Aquarium will host an exhibit of its sculptures and collages.

Those who walk ocean and lake beaches see the accumulated debris. Some may try to ignore it. Others may abandon their favorite places for recreation and relaxation because they can no longer bear the unsightly wreckage. Plastics impact every living creature.

Kamikatsu, Japan, famously declared its goal was to go waste-free by 2020. It didn’t quite get there.

One of the many unfortunate outcomes of the coronavirus pandemic has been the quick and obvious increase in single-use plastic products. After COVID-19 arrived in the United States, many grocery stores prohibited customers from using reusable bags, coffee shops banned reusable mugs, and takeout food with plastic forks and knives became the new normal.

Despite recent scientific evidence that reusables don’t transmit the virus, the plastic industry has lobbied hard for a return to all things disposable plastic. Inevitably, a lot of that plastic will continue to flow into our environment.

While COVID-19 has certainly thrown a wrench into the hard-earned progress we’d been making in reducing waste, eliminating plastic pollution entirely was always going to be challenging — with or without a pandemic. The jarring rise of single-use plastics is an expedited version of a familiar trend. Plastic production has been steadily increasing for quite some time.

As a zero-waste advocate, I’ve seen how the tsunami of plastic continuously being produced and flooding our planet has made achieving zero-waste goals incredibly difficult. The sheer amount makes it hard to safely and efficiently dispose of plastic, no matter how hard we try.

But as I examine the problem, and search for solutions, I keep coming back to one noteworthy example.
