Earlier this year, the city of Nottingham gloriously unveiled their first 30 double-decker buses powered entirely by food waste, farm waste and sewage – making Nottingham one of the UK’s greenest transport cities.
A further 23 buses will be added to the roads early next year.
The initiative joins the movement of bio-fuel buses in the UK with similar schemes already in place in London, and with Bristol soon to follow.
The buses run on bio-gas innovation developed by Swedish company Scania. This technology turns naturally produced waste into fuel by capturing methane emitted during anaerobic digestion processes.
“When this fuel is used, emissions are 84% lower than their diesel counterparts, thereby making them – from ‘Well-to-Wheel’ – the greenest buses on the road”, states Nottingham City Transport (NCT) Engineering Director, Gary Mason.
The move to bio-gas comes amidst growing concerns over air pollution levels, which has prompted a new draft of the Air Quality Plan for tackling nitrogen dioxide (NO2).
It has been reported that 37 of the 43 air quality zones currently fail to meet the legal limit set by the European Commission on NO2 levels. However, Nottingham’s greener double deckers are expected to reduce the city’s nitrous oxide emissions by 36,000kg.
During this period of uncertainty following Brexit, the move to bio-gas buses is an encouraging effort to improve air quality in the UK and foreshadows an optimistic future for greener transport opportunities.
