UK startup creates ‘smart’ plastic that self-destructs in the sea

Plastic debris in the sea, lingering beneath the surface

University of Edinburgh start-up firm EVA Biosystems has developed a plastic that is described as being able to sense when it’s in the ocean and break itself down without creating microplastics.

The solution secured top prize in the SSE-sponsored Net Zero category at this year’s Converge Awards, an annual awards ceremony intended to celebrate and reward Scottish academic innovation.

EVA Biosystems seemingly impressed judges with its novel approach to tackling plastic pollution, earning 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 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 Dr 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.”

EVA Biosystems’ innovation involves adding special bacteria to conventional plastics. These bacteria can detect when they’re in environments like seawater and activate enzymes that break down the plastic. Unlike chemical degradation, which can create harmful microplastics, E.V.A’s unique technology can prevent these waste products. According to recent research, up to 12 million metric tons of plastic are dumped into the world’s oceans every year – the equivalent of more than 100,000 blue whales.

The Create Change category, which focuses on creative, social, and impact-driven enterprises, was won by Ujamaa Spice, also from the University of Edinburgh. Founded by Jawahir Al-Mauly, Ujamaa Spice is revolutionising the £17 billion global spice industry by forging close partnerships with smallholder farmers in Zanzibar and assuming full control of their supply chain. This approach ensures exceptional quality spices for UK consumers while combating food crime and exploitation in the industry.

In the KickStart category, designed for early-stage ideas, SEASAT from the University of Edinburgh secured top prize. Founded by Solomon White, SEASAT uses satellite images and machine learning to monitor coastal water conditions, providing an early warning system for the aquaculture industry. This allows fish farms to predict and react to potential threats, enhancing their operational efficiency.

The Net Zero category also saw SolarSub from the University of Edinburgh as runner-up. Co-founded by Sebastiaan Schalkwijk and James Taylor, SolarSub has developed a highly efficient cooling system for floating solar panels, addressing the challenge of overheating and reduced efficiency in water-based solar farms.

PalmAlt from Queen Margaret University was one of two runners-up in the KickStart category. Created by Catriona Liddle, PalmAlt offers a 100% replacement for palm oil-based shortening in bakery products, addressing sustainability concerns while improving nutritional profiles.

Adam Kosterka, executive director of Converge, commented on this year’s cohort:

“The calibre of innovation emerging from Scotland’s universities continues to be world-class. E.V.A. Biosystems, Ujamaa Spice, SEASAT, SolarSub, and PalmAlt are shining examples of how academic brilliance can lead to groundbreaking solutions with global potential. These companies are not just creating products; they’re shaping a more sustainable and inclusive future for Scotland and beyond.

“At Converge, we’re privileged to support innovative university founders by providing them with the business acumen and networks that complement their technical expertise. Together with Scotland’s universities, we’re helping to create an environment where transformative ideas can evolve into successful businesses, contributing to our nation’s reputation as a leader of technological advancement and entrepreneurial spirit.”

Deputy First Minister Kate Forbes said:

“Translating world-class research from our universities into new innovative technologies and businesses is key to delivering on Scotland’s National Innovation Strategy to drive economic growth.

“Converge plays a vital role in providing a supportive environment for innovators and entrepreneurs to showcase their ideas and connect with investors, mentors and industry leaders.

“I congratulate this year’s winners, who are addressing global challenges and bringing positive change across the country.”

Funded by the Scottish Funding Council and a network of eight corporate partners, Converge works in partnership with 18 of Scotland’s universities. Since its launch in 2011, the programme has trained over 670 aspiring founders and supported the creation of over 420 companies that enjoy an above-average three-year survival rate of over 80% (as of 1 June 2024).

Open to students, recent graduates, and staff, Converge supports new businesses through intensive business training, networking, 1-2-1 support, generous equity free cash prizes and expert, professional advice from its roster of industry partners.
