E.V.A. Biosystems, a start-up emerging from the University of Edinburgh in Scotland, has developed a novel plastic that self-destructs in marine environments without generating microplastics.

The innovation recently secured the top prize in the Net Zero category at the Converge Awards, highlighting its potential impact on the food and beverage industry amid increasing scrutiny over sustainability practices.

The start-up's technology integrates special bacteria into conventional plastics. These bacteria can detect seawater and activate enzymes to break down the plastic, effectively mitigating the environmental hazards posed by traditional plastic waste.

Dr Alexander Speakman, founder of E.V.A. Biosystems, notes that while biodegradable plastics exist, they are often prohibitively expensive and constitute only about 1% of global plastic use.

“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,” he said.

The urgency of this innovation is underscored by alarming statistics: approximately 12 million metric tons of plastic enter the oceans annually, equating to more than 100,000 blue whales.

The company received £30,000 in cash and £19,500 in business support from SSE and Converge’s network of industry partners to further develop its technology.

Additionally, E.V.A. Biosystems won the IBioIC Award, which recognises innovative biotech solutions that meet market needs, earning an extra £20,000 for the University of Edinburgh.

E.V.A. Biosystems' approach could resonate with food and beverage manufacturers facing increasing pressure to adopt sustainable packaging solutions.

This development comes at a time when the food and beverage sector is under scrutiny for its environmental impact, particularly regarding single-use plastics. Industry players are increasingly seeking alternatives that align with consumer demand for sustainability.

E.V.A. Biosystems' technology could provide a viable option for companies looking to enhance their environmental credentials without sacrificing performance.

The Converge Awards also recognised other projects, including Ujamaa Spice, which focuses on ethical sourcing in the spice industry, and SEASAT, which uses machine learning for aquaculture monitoring.

Adam Kosterka, executive director of Converge, noted the importance of supporting innovators like E.V.A. Biosystems: "These companies are not just creating products; they are shaping a more sustainable future".
