94% of European households throw UCO down the sink generating catastrophic environmental impact. The most disruptive being the effect on aquatic ecosystems and fat-berg sewer blockages. Bi-Oleum is an affordable easy-to-use household kit that attempts to solve this issue. It incorporates a non-pathogenic bacterial strain to bioremediate and remove domestic UCO, producing a clean output. This project challenges current human behaviours by incorporating a living, unharmful bacteria into our daily lives to achieve a sustainable biodesigned solution.
