A university startup has developed a plastic that can detect when it is in the ocean and automatically breaks itself down without creating harmful microplastics.

The breakthrough technology, developed by EVA Biosystems, addresses one of the world’s most urgent environmental challenges.

The solution was recognised in his year’s Converge Awards, which celebrate Scottish academic innovation.

EVA Biosystems earned a £30,000 cash prize and £19,500 of in-kind business support from SSE and Converge’s network of industry partners to develop the business.

The company also won the IBioIC Award, a prestigious prize presented to an innovative biotech business with a product or process that addresses a real market need, netting £20,000 for the University of Edinburgh.

“We’re all struggling with plastic pollution, and while there are many people developing biodegradable plastics, they’re too expensive and only make up about 1% of the world’s plastic,” said Alexander Speakman, founder of EVA Biosystems.

“Our technology works with existing plastics, making them ‘smart’ enough to break down when they end up where they shouldn’t be, like in our oceans or landfills.”

Adam Kosterka, executive director of Converge, said: “The calibre of innovation emerging from Scotland’s universities continues to be world-class.

“These companies are not just creating products; they’re shaping a more sustainable and inclusive future for Scotland and beyond.”
