Seaweed fermentation revolution: unlocking sustainable solutions at Edinburgh's Heriot-Watt University

March 19, 2024

The FlexBio project at Heriot-Watt University is showcasing the innovative use of bacteria to derive valuable products from seaweed, signaling a new era in sustainable biotechnology.

At Edinburgh's Heriot-Watt University, a pioneering project demonstrates the power of bacteria to extract valuable elements from seaweed, offering a glimpse into the future of sustainable bioprocessing. The FlexBio facility, managed by Neil Renault and backed by the Industrial Biotechnology Innovation Centre (IBioIC), is scaling up fermentation processes to transform algae into a source for pharmaceuticals, biopolymers, and potentially even electric vehicle battery components.

Seaweed, once a staple for basic needs, is now at the forefront of biotechnological research. The FlexBio facility's unique approach involves pre-processing and fermenting seaweed to stabilize key biochemical constituents, adapting to client-specific needs. This method not only accelerates the fermentation process but also enhances understanding and control over the production of desired products.

FlexBio serves a critical role in bridging experimental stages to industrial-scale processes, offering services that maintain client confidentiality and intellectual property ownership. With equipment funded by Marine Fund Scotland and the Scottish Funding Council, the facility is a testament to Scotland's commitment to growing its bioeconomy sector. Renault highlights the importance of cost-effectiveness and market demand in developing scalable bioprocessing solutions.

The potential applications for seaweed-derived products are vast and varied, from replacing plastic packaging to creating sustainable alternatives to lithium batteries. As demand and interest in FlexBio's services increase, the project underscores the untapped potential of seaweed in driving a sustainable future. The collaboration between IBioIC, Heriot-Watt University, and industry partners points to a vibrant ecosystem ready to explore new frontiers in biotechnology.
