A University of the Free State (UFS) researcher is shaking up the fight against plastic pollution with groundbreaking research into biodegradable polymers. Dr Julia Puseletso Mofokeng, a senior lecturer, is exploring how these environmentally friendly alternatives can replace harmful petroleum-based plastics in disposable product packaging.
Plastic pollution is no joke, with millions of tonnes ending up in our oceans and ecosystems every year. But thanks to Mofokeng, there’s hope for change.
She believes biodegradable polymers could be the key to reducing plastic waste and protecting the environment, calling on industry leaders and policymakers to push for their use in packaging.
Mofokeng’s journey began in her hometown of Bophelong in Qwaqwa, Free State. Growing up, she witnessed plastic waste being burned and dumped in her community, sparking her passion to find a solution. Now, her research aims to tackle the environmental havoc caused by plastic waste, ensuring cleaner water and reducing pollution.
The real game-changer? These biodegradable polymers come from natural sources like vegetable oils and starches, and break down without leaving harmful residues.
“My research focuses on creating completely biodegradable polymer blends that can replace petroleum-based plastics,” says Mofokeng. “By adding natural fibres and minerals, we can match their properties and ensure they’re just as strong.”
The promise of biodegradable polymers
The beauty of biodegradable polymers is that they degrade quickly, unlike traditional plastics that can linger in the environment for centuries. In fact, some of Mofokeng’s experiments show these eco-friendly materials breaking down in just a few months under the right conditions.
With more food outlets and restaurants already opting for bio-based packaging, Mzansi seems to be moving in the right direction. But Mofokeng stresses the importance of stricter regulations to make biodegradable packaging the norm.
She and her team are also diving into new research, collaborating with local communities in Qwaqwa to tackle groundwater contamination using these advanced materials. It’s all part of Mofokeng’s mission to not only clean up the planet but also make sure everyone has access to safe drinking water.
Her work is making waves, both locally and globally. Mofokeng has built research partnerships with institutions in Libya and Serbia, and her research group continues to grow, inspiring the next generation of scientists dedicated to sustainable solutions.
