London, UK — December 2025 — Seaweed Greens — the ocean innovation company nominated for The Earthshot Prize by The Mills Fabrica, a leading global incubator for sustainable and materials innovation — is bringing its regenerative vision to central London with a striking scientific-art activation launching 15 December.
A single London taxi has been wrapped with artwork derived from magnified microgreens grown using Seaweed Greens’ pioneering sargassum-based biostimulant. The imagery showcases the intricate architecture of plant roots supported by the company’s breakthrough process that removes arsenic and toxins at scale, solving one of the biggest barriers to safe global sargassum use.
The technology — developed by British engineer and founder Andrew Sneath, together with British-American artist, co-founder, and museum-collected creative Camilla Webster — represents a major advancement in coastal management, regenerative agriculture, and climate-smart soil systems. Both founders bring decades of innovation across engineering, environmental design, and fine art, including Webster’s work featured by the U.S. State Department’s Art in Embassies Program and the World Expo in Japan.
To create the taxi’s visual centerpiece, Sneath captured laboratory images of microgreens grown in sargassum-enhanced media. Webster transformed this scientific data into contemporary botanical artworks inspired by medieval manuscripts and early naturalist drawings — merging ancient observation with modern environmental technology.
“These artworks reveal nature’s hidden architecture when waste becomes value,” said Webster. “They show the public what regeneration looks like — emotionally, visually, and scientifically.”
“Our technology converts a global ocean challenge into a high-performance agricultural solution,” said Sneath. “We can now safely process toxic sargassum at scale, sustainably and profitably, turning a coastal crisis into renewable agricultural inputs.”
Seaweed Greens is currently in discussions to supply its biostimulant, organic byproducts, and British-engineered processing systems to governments, resorts, agricultural enterprises, and coastal operators across the Caribbean, the UK, and other international markets.
The global sargassum crisis — spanning West Africa, the Caribbean, Mexico, and Florida — has created urgent demand for solutions that are safe, scalable, and economically viable. Seaweed Greens’ platform converts this challenging biomass into clean, regenerative agricultural materials while supporting coastal cleanup and local economies.
The London taxi activation offers a rare, visually arresting moment at the intersection of art, science, and environmental engineering, inviting Londoners to reimagine how creativity and technology can address some of the planet’s most pressing challenges.
