Following in the footsteps of the famous Bristol ‘poo bus’, which was the first in the UK to be powered by biomethane, Wessex Water’s new trucks run on bio-CNG and are helping reduce the company’s carbon emissions and fuel costs, besides representing a transport revolution that could potentially slash greenhouse gas emissions and improve local air quality. Each vehicle converted from diesel to biomethane achieves a carbon saving that is equivalent to removing more than 100 cars from the roads.
All fuel used in the trucks, which are hitting the roads this summer, comes from the anaerobic digestion of sewage and food waste at Bristol Bioresources and Renewable Energy Park.
“The tankers collecting sewage sludge for treatment and the trucks delivering the output fertilizer are both powered by the gas generated from this treatment, so we’re closing the loop when it comes to our recycling,” said Sean Hill, Wessex Water’s director of bioresources. “This will make a huge difference to our carbon footprint and help improve the air quality of communities in our region, as well as improving operational efficiency and bringing cost benefits.”
“Two vehicles have been purchased initially and we hope to eventually roll out the use of bio-CNG across our entire tankering and biosolids fleet,” he added.
Wessex Water is the first water and sewerage company to transport both sludge and biosolid fertilizers using vehicles powered by gas from the waste it is treating.
