From crustacean waste to battery electrodes (RD148)

Project Outcome:

The research focused on further developing microbial extraction methods of chitin from crab waste and converting chitin into a bio-carbon and activating electrodes for the use in Sodium-Ion batteries. ROR worked with ULB Brussels on extraction methods and this resulted in a clear pathway for how microbes can be used as an alternative extraction method for chitin, replacing conventional chemical processes. This sustainable method ensures the production of a true ‘green’ chitin and aims to reduce chemical secondary waste streams that result from traditional chemical processes.

ROR closely worked with Swansea University and Greenmatt Labs (University of Liege) exploring the electronic conductive capacities of a chitin-based bio-carbon. Tests indicated that chitin is a very suitable natural resource to be integrated in sustainable battery technology, mainly Sodium-Ion and Redox Flow batteries. ROR was supported by the University of Exeter to conduct regional and global market studies related to the UK fishery production, the legislative environment, and global chitin and battery markets. The funding also allowed for ROR to engage directly with stakeholders in the UK crab industry and closely collaborate with the Shellfish Association of Great Britain (SAGB).

ROR was able to construct an evidence-led business plan and is currently pursuing further public and private funding opportunities in collaboration with their research partners. ROR is aiming to initiate a pilot-scale plant for chitin extraction in 2025 and aspires to start construction of a larger factory by the end of 2026, potentially leading to the creation of 50 new jobs in the South-West of England.
