An innovative new project called LIFE+ Methamorphosis is pioneering a new sustainable biofuel for cars. Car company SEAT and water management company Aqualia have transformed wastewater into the alternative fuel. Powered with this biofuel produced during one year at a treatment plant in Spain, a vehicle could circumnavigate the globe 100 times.
SEAT and Aqualia came up with a creative answer to the issues of pollution from traditional car fuels – which have led to traffic restrictions in cities like Madrid – and reusing water, a scarce resource. To make their biomethane, wastewater is separated from sludge in treatment plants, and then becomes gas after a fermentation treatment. Following a purification and enrichment process, the biogas can be utilized as fuel. Compared against petrol, production and consumption of the biofuel releases 80 percent less carbon dioxide, according to SEAT. The new biofuel works in compressed natural gas (CNG)-fueled cars.
The project aims to show feasibility at industrial scales through two waste treatment systems. The UMBRELLA prototype will be set up in a municipal waste treatment plant serving Barcelona. The METHARGO prototype will create biomethane at a plant handling animal manure. The biogas made with the second prototype can be utilized directly in cars or could be added to the natural gas distribution network, according to the project’s website.
A mid-sized treatment plant can handle around 353,000 cubic feet of wastewater every day, which could yield 35,000 cubic feet of biomethane, according to companies involved with the project. All that biomethane could power 150 vehicles driving around 62 miles a day.
SEAT will supply vehicles to test the biofuel over around 74,500 miles. The European Commission is funding the project. Other companies participating include Fomento de Construcciones y Contratas, Gas Natural, the Catalan Institute for Energy, and the Barcelona Metropolitan Area.
