Mersea Farming is a purpose-led business dedicated to making a real impact on people, planet and the future of sustainable food and energy. At our core, we believe business should be a force for good and we put this into practice by empowering vulnerable groups (including the homeless, ex-military personnel and youth), through meaningful employment and pathways to shared ownership. By offering not just jobs but also a stake in the company, we help build financial security and long-term dignity for those who need it most.
Our innovative approach centres around growing both micro and macro algae, supplying processors with high-quality raw materials to develop cutting-edge products for food, feed, biofuels and beyond. Algae farming is one of the most resource-efficient, climate-positive agricultural practices available today. It enhances marine biodiversity, sequesters carbon and requires no freshwater or arable land.
Mersea Farming operates with a community-owned innovation model. We start with Mersea-led operations and transition ownership of our farms to community members from vulnerable backgrounds. This hybrid structure ensures quality and impact from day one, while embedding long-term social value through inclusive ownership.
With people, planet and purpose at the heart of everything we do, Mersea Farming is pioneering a new wave of ocean-based, inclusive climate solutions. We welcome partners, collaborators and supporters to join us in growing a sustainable and equitable algae economy.
High above Liverpool’s iconic skyline, the Liver Bird stands watch, its emerald wings outstretched to the wind. For centuries, this mythical creature has embodied the city’s resilience and spirit, proudly gripping a strand of algae (locally known as "lava seaweed") in its beak. Legends have sparked curiosity: why seaweed? The answer lies in Liverpool’s origins as a bustling port city deeply entwined with the ocean’s rhythms.
The seaweed in the Liver Bird’s beak symbolises Liverpool’s enduring connection to the sea, a vital thread that links the city’s maritime past to its innovative future. For generations, this detail has reminded communities that the sea, with all its mysteries and resources, is both a protector and provider. It is a symbol of nourishment, regeneration and the unyielding possibilities that flow from our coastal roots.
Mersea Farming draws inspiration from this enduring emblem. Our journey back to Liverpool is not just a return to a city, but a reconnection with the very source of life: the ocean. Through sustainable algae farming, we honour the Liver Bird’s spirit - creatively reimagining seaweed as a cornerstone for regeneration and environmental renewal.
Algae, like the lava seaweed grasped by our city’s powerful symbol, is more than a resource; it’s a catalyst for community empowerment and marine innovation. By cultivating algae, we help regenerate local ecosystems, support sustainable livelihoods and ignite a wave of positive change for Liverpool and beyond.
Together, we celebrate heritage and embrace a shared future, one where the Liver Bird’s legacy takes flight in every strand of algae we harvest and every life our work touches.

Our advanced algae systems provide natural, effective solutions for treating contaminated water sources. Through photosynthetic processes, our cultivated algae absorb pollutants, heavy metals and excess nutrients, transforming contaminated water into clean, safe resources.

Specialised solutions for the mining industry, addressing the environmental challenges of tailing ponds. Our micro algae cultivation system transform these contaminated water bodies into productive ecosystems whilst extracting valuable minerals and reducing environmental liability.

Converting algae biomass into high-value commercial products. Our processing capabilities transform cultivated algae into biofuels, nutritional supplements, agricultural fertilisers and industrial materials. Creating economic value from environmental remediation.
