Barcelona buses could soon be running on sewage sludge. In fact, the Catalan city tries to make use of biofuel for the city’s immense public transport system. What’s more, the city is launching a pilot project to produce biomethane, a renewable natural gas, from sewage sludge.
This is a part of the Nimbus Project which receives funding from the European Union. The project aims to encourage a circular economy, starting with greener public transport. Transportes Metropolitanos de Barcelona (TMB) is the Catalan capital’s main public transport operator. TMB stated that 70 per cent of its fleet ran on diesel fuel in 2010. However, around 75 per cent of the buses were hybrid or running on less polluting energy in 2020. It’s still far from the EU’s commitment for over 30 percent of energy consumption for transport from renewable sources by 2030.
