In the Swedish city of Västerås, regional public companies for energy, water and waste cooperate with a real estate company in order to reduce blockages in the sewer system; blockages mainly caused by used cooking oil being poured down the drains. The companies use the EkoFunnel together with information brochures to inform people on how to dispose of the used cooking oil and to facilitate collection. Ones filled with used cooking oil, the bottles are taken to collection points in the area.
The cooking oil is then taken to the regional waste company where the bottles are emptie and the oil is used for production of biogas. The biogas is used as fuel for the public transport in Västerås and Stockholm.
