Barcelona to Fuel City Buses Sustainably with Sewage


A groundbreaking discovery in Barcelona has revealed that brown nuggets might hold the key to the city’s future energy needs. The innovative project, known as NIMBUS (Non-IMpact BUS), aims to power a fleet of buses with the waste produced by the city’s residents.

Contrary to popular belief, this isn’t just a load of BS. The concept behind NIMBUS revolves around harnessing the natural gas produced from organic matter, such as poop, through a process called anaerobic digestion. This gas, primarily methane, can then be used to fuel engines designed for natural gases like propane.

The resulting fuel, known as “biomethane,” is a sustainable and eco-friendly alternative to traditional fuels. Barcelona isn’t the only city getting in on the action – the Glenfiddich Scotch distillery in Europe has also discovered a way to produce biogas from barley waste left over from the whiskey-making process.

According to Rubén Ruiz, the general manager of Aigües de Barcelona, waste recovery projects like NIMBUS are essential for promoting sustainable mobility and achieving an ecological transformation in urban environments. By converting waste into energy, Barcelona is embracing a circular economy model that prioritizes environmental responsibility.

Javier Lafuente, from the Universitat Autònoma de Barcelona, emphasized the importance of utilizing technology to transform water treatment into an opportunity to recover valuable resources, both material and energy-wise.

In a nutshell, Barcelona’s poop-powered buses are a key component of the city’s commitment to sustainability and environmental stewardship. As residents gear up to utilize this innovative public transit system, it’s clear that Barcelona is leading the way in revolutionizing urban planning and transportation for a more sustainable future.
