Abstract
As a naturally occurring resource around the UK coastline, seaweeds continue to gain recognition both nationally and internationally, as one of the most sustainable and energy efficient feedstocks for use within a circular bioeconomy. Seaweeds are known to contain a wealth of valuable compounds locked up within their structures, for applications in pharmaceuticals, nutraceuticals, food and cosmetics, or conversion into biofuels. This comes at an imminent time of need as we need to find alternative sources, or feedstocks, to replace petrochemically derived materials and fuels in the hope to prevent climate change, and to also create more environmentally friendly chemicals and products. Research has revealed the exciting potential seaweeds have to help tackle some of our current global issues through the development of cascading biorefinery processes which are capable of producing multiple valuable products. However, a number of key challenges still exist which are preventing the scalability and commercialisation of seaweed-based processes and products. In my pioneering research, I have already shown viable processing routes for producing novel bioproducts from seaweed, within a biorefinery concept, and with this Future Leaders Fellowship I will firmly put the seaweed-based circular bioeconomy on the engineering and polical landscape of the UK, and world-wide. To achieve this, I will build upon the seaweed process already established in my research, however with the specific aim of overcoming unique challenges hindering the development of seaweed biorefineries. New approaches of biomanufacturing valuable products, food/feed sources and materials (for bioplastics and natural materials applications) and biofuels from seaweed will be explored. Process waste-stream fractions will also be utilised to minimise waste. Novel reactor devices operating under continuous flow will be built to make the recovery of valuable products, such as polysaccharides, more efficient with potential to be scaled up to industrial level. The environmental impacts and costs of the new processes will be assessed to ensure that the new biomanufacturing processes are sustainable, environmentally friendly, and profitable. Furthermore, strategies will be put in place during this Fellowship to make sure there is public acceptance of seaweed biorefinery research and to promote the potential of building a sustainable UK seaweed industry, particularly within coastal communities. Engagement links with policy makers will also be established to facilitate the alignment of government policy establishing seaweed as UK sustainable resource. With all these ingredients for a circular seaweed bioeconomy addressed, the UK will be ready to make the transition to a greener bioeconomy thanks to research the research proposed in my Fellowship, and the Fellowship will enable me as a woman to become a champion of cutting-edge research for net-zero.

Seaweed and the bioeconomy: enabling growth through aquaculture policy
| Description | The majority of time spent in the past year was focussed on setting up a new laboratory space, and as such, research only commenced in early December 2025. As there was a delay in starting research, significant progress was made on the responsible research and innovation (RRI) and policy work set out in this fellowship. The first RRI work package was held in Oban, Scotland and findings from this stakeholder workshop identified key challenges that need to be overcome in order to make UK seaweed biorefineries for the manufacture of bio-based products become a reality. Seaweed pre-processing steps such as sustainble drying emerged as a major bottleneck the industry is facing. This has been highlighted area of importance that warrents further exploration and collabaration with seaweeed farmers, either within this fellowship or through other funding means. A review of the aquaculture policy landscape and interviews with stakeholders across the seaweed value chain were held, and a policy brief was written and published that details four key recommendations to support the UK seaweed industry including: 1. Understanding of market potential of seaweed-based products; 2. To streamline the licensing and permitting process for seaweed aquaculture; 3. To establish a dedicated UK body for the seaweed industry; 4. Provide financial support for the industry. Laboratory research started 3 months ago due to laboratory set up delays, and in this short time, an optimised process for the precipitation of seaweed polysaccharides has been identified. Both alginate and fucoidan polysaccharide precipitation times have been reduced. This is a significant finding as these fundamental trials will aid with the design and building of our continuous processing reactor. |
| Exploitation Route | Researchers and industries working in the field with a focus on polysaccharide extraction could use these findings. However, we would ideally like to patent our process and decide how to best licence out our technology (once built). The policy brief has detailed recommendations that could be used by policymakers to support an upscale of the seaweed industry in the UK. The publics could use the published policy brief to enhance their understanding and acceptance on the use of seaweeds for the bioeconomy. |

| Description | UK-Mexico Collaboration |
| Organisation | Autonomous University of Coahuila |
| Country | Mexico |
| Sector | Academic/University |
| PI Contribution | Contributions made by myself to this new collaboration include the external supervision of 2 PhD students (under the supervision of Dr Hector Ruiz) who are also working on seaweed bioprocessing methodologies and intellectual input to their theses and publications (one book chapter has already been published and a research article has just been accepted for publication in Bioresource Technology). There will also be the opportunity for Dr Hector Ruiz to visit UCL (hopefully, depending on Covid) for future research area discussions and a research seminar. |
| Collaborator Contribution | Dr Hector Ruiz has provided intellectually insight and support to a review article I wrote during lockdown, related to the topic of my BBSRC Discovery Fellowship. This manuscript has been submitted for review to the journal Renewable and Sustainable Energy Reviews. Furthermore, Dr Ruiz and myself are in discussions about new research project ideas and collaboration related to the seaweed-infestation problems Mexico is currently facing, and ways in which we can support each others research. |
| Impact | A book chapter has been an output from this collaboration: https://doi.org/10.1016/B978-0-12-817943-7.00015-9. A research article 'High-pressure technology for Sargassum spp biomass pretreatment and fractionation in the third generation of bioethanol production' has just been accepted for publication in Bioresource Technology (no DOI yet, paper was accepted 2 days ago). A review article 'Macroalgal Biorefinery Concepts for the Circular Bioeconomy: A Review on Biotechnological Developments and Future Perspectives' (lead author ETK) has been written in collaboration with Dr Ruiz and has been submitted for review. Finally, I was recently awarded a small pot of funding from UCL's Global Engagement Fund (£4k) to enable myself and Dr Ruiz travel to each others' research institutes for a tour of the research centers and discuss new collaborative projects that will compliment our research areas. Research seminars will also be held between the two groups. Also, we are aiming to discuss ways that UCL and the Autonomous University of Coahuila can 'fight Mexico's seaweed infestation problem with biotechnology' through collaborative research project ideas and potential funding calls we can apply to. Dr Ruiz will also be a key collaborator (related to this topic) for any potential future Fellowship/Lectureship positions I intend to apply for. |

| Results and Impact | 70 individual stakeholders in the seaweed sector attending this workshop on seaweed biorefineries, in order to for my and my group to gather data on how different stakeholders feel about the future of the seaweed biorefineries. They were given the opportunity to express their hopes, concerns and current challenges that are preventing this sector from growing, and also discussed what needs to be done to overcome these challenges so we can achieve our hopes for this sector. Data was collected and a report was written by me in this workshop. Data from this workshop was used in a policy brief that was recently written by me and my policy adviser at UCL. |
