Revolutionary Breakthrough: Scientists Transform Plastic Waste into Carbon-Eating Material

Experts estimate that plastic production and disposal release nearly 2 billion tons of greenhouse gases annually. Most of this plastic waste ends up in landfills. But what if we could transform some of this waste into a tool for fighting climate change?

A research team in Denmark might have found just that. In a recent study published in Science Advances, they developed a method to convert decomposed PET (polyethylene-terephthalate) plastic into a material capable of capturing carbon. “The beauty of this method is that we solve a problem without creating a new one,” said Margarita Poderyte, the lead author and a chemistry PhD candidate at the University of Copenhagen.

As the planet warms, scientists are racing to find ways to remove carbon dioxide (CO2) from the atmosphere. Meanwhile, the plastic waste crisis grows, threatening both human and environmental health. This innovative study aims to address both issues.

Using a process called aminolysis, the researchers transformed PET—a common plastic found in bottles and food packaging—into a sorbent material known as BAETA. This powdery substance can be shaped into pellets that efficiently absorb CO2. In fact, one pound of BAETA can capture up to 0.15 pounds of CO2, which is impressive compared to many existing systems.

BAETA is also more heat-resistant than other materials used for carbon capture, remaining effective at temperatures up to 482°F (250°C). However, it does require more energy to reach its maximum absorption capacity. The researchers believe that despite potential costs, BAETA could be a practical solution on a larger scale.

Humans generate a staggering amount of PET waste. Recent studies revealed about 27 million tons of plastic particles floating in the North Atlantic, with unknown effects on marine ecosystems. Poderyte emphasized that if we can access the decomposed PET plastic in oceans, it could serve as a valuable resource for this new method.

“Our material can create a clear economic incentive to cleanse the oceans of plastic,” said Jiwoong Lee, co-author and associate professor at the University of Copenhagen. This innovative approach not only tackles climate change but also offers hope for reducing marine pollution, proving that the solutions to these pressing issues are interconnected.

This research highlights how repurposing waste can lead to innovative solutions. As the climate crisis intensifies, sustainable methods like BAETA become vital. Keeping up with these developments can inspire action and hope for a cleaner, healthier planet.
