Introduction

Aguas de Murcia (Emuasa) designed and started up a plant where biogas is cleaned and later transformed into an ecological automotive fuel at the Murcia East Sewage Plant for use by company vehicles.

Objectives and target audience

Citizens:-
•    Show citizens the environmental possibilities of managing the city’s sewage;
•    Show citizens technologies for transport as an alternative to fossil fuels.

Financial Resources and Partners involved

Process

Results

• To prevent the emissions that contribute to the greenhouse effect as one ton of methane gas released into the atmosphere has the same effect as 21 tons of carbon dioxide;
• To reduce carbon dioxide emissions given that the fuel that is produced by the process produces less carbon dioxide emissions than any conventional fuel such as gasoline or diesel oil.  Also including the fact that it is cheaper;
• Biogas does not contain lead, it makes it possible to eliminate nitrogen oxide emissions and other contaminants.  It also makes it possible to replace one fossil energy source for a renewable energy with prevention of the production of odours that come from the emissions of sulphur compounds.

Critical Success Factors / Challenges

One major factor for success was due to the appropriateness and the technical performance of the gas cleaning system.  Another factor for success of the plant is the viability of renewable energy in vehicles.  This would be noticed by citizens and would cause a gradual increase of renewable vehicles by citizens.

How could it be transferred to another municipality/organisation?
By studying the possibility of implementing similar treatments at their sewage plants.
