94% of European households throw Used Cooking Oil (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 bacterial strain to bioremediate and remove domestic UCO, producing a clean output that be used to water plants. This project challenges our current human behaviour by incorporating a living unharmful bacteria in our daily lives to achieve a sustainable bio designed solution.
