Citywide develops and adopts technology to drive improvement in environmental performance.
The first service company in Australia to use compressed natural gas (CNG) in waste vehicles, Citywide continues to trial emerging technologies for application on customer contracts.
North Melbourne Asphalt Plant
In February 2008, Citywide opened the doors of its redeveloped North Melbourne asphalt plant, the most environmentally sensitive asphalt production facility in the Southern Hemisphere. The new plant is designed to achieve gas and electricity consumption savings of over 30% and also reduces noise, dust and odour. It produces standard mix asphalt as well as recycled (RAP) and Citywide Greenpave asphalt.
Greenpave
A producer of asphalt and provider of road maintenance services, Citywide investigated energy use and the level of emissions produced along its supply chain with the aim of reducing its carbon footprint and that of its customers.
In 2007 Citywide partnered with Shell to produce Australia’s first warm mix asphalt, Citywide GreenPave, which achieves 30% reduction in fume emissions, 30% reduction in greenhouse gases, 55% reduction in fine dust and energy savings of up to 30%.

Alternate Fuel Trials
Citywide is continually reviewing the latest in alternative fuel technology. The recent trial of a new LPG system has seen a number of units fitted to waste compactors in the City of Manningham Citywide’s duel fuel LPG trial has confirmed that by combining the two fuels a far higher percentage (between 95% and 97%) of the diesel fuel is burnt during the combustion cycle. This results in reduced emissions, lower exhaust temperatures and improved fuel consumption.
Significant tangible benefits of the trial have included:
- a massive 10-15% reduction in fuel costs
- a 12% reduction in NOx
- a reduction of CO2 emissions of up to 14%
- lower exhaust temperatures
- cleaner oil
