An innovative project demonstrates how waste can be transformed into biomethane, reducing emissions and contributing to sustainable mobility.
The transition to clean and sustainable energies advances with projects that surprise by their creativity. A striking example occurs in Barcelonawhere An urban collective works thanks to a fuel produced from human excrements.
Although it sounds unusual, the key is in the sludge that comes from wastewater, which are transformed into biomethane. This renewable gas allows carbon dioxide emissions to be reduced by 80% compared to traditional natural gaspositioning itself as a much more friendly alternative with the environment.

In the Catalan capital, A V3 line bus has been driving for five years driven by this biofuel. Experience is part of the Nimbus projectdeveloped by Veolia, Metropolitan Transport of Barcelona (TMB) and the Autonomous University of Barcelona.
Its objective is clear: Convert daily waste into a valuable energy resource within the logic of the circular economy.

The process consists of Treat four cubic meters of mud per hour, of which purified biomethane is obtained thanks to the combination of carbon dioxide with hydrogen from renewable sources. The result is a clean fuel and with great expansion potential.
The success reached opens the door to a production on a larger scale, promoted by European financing. The goal is that more public transport units can stock up with this gasmarking a concrete advance towards a more sustainable urban future.
