By modernising the humble waste truck, STG Global is set to shake-up Australia’s waste management sector. Regan Yendle, STG Global Director, explains.
Adelaide waste and resource recovery authority East Waste will commission South Australia’s first fully electric-powered waste collection truck in December.
East Waste will install a 30 kilowatt solar system at its Ottaway depot to provide renewable energy to charge the truck’s batteries.
The truck, supplied by Australian company Superior Pak with drivetrain technology from SEA Electric, will be the first in a fleet replacement program.
East Waste Chairman Brian Cunningham said the new truck will replace a diesel-powered truck and remove the equivalent of 20 vehicles generating 63 tonnes of carbon dioxide every year.
“This is much more than a terrific environmental initiative by East Waste. It will create financial gain to better manage the cost of kerbside collections of recyclable resources and waste,” Mr Cunningham said.
“We conservatively project that our new electric truck will save in excess of $220,000 over the seven-year life of a diesel truck.”
Mr Cunningham said the truck’s drivetrain generates electricity each time it reduces speed, which returns charge to the batteries.
“Residents in suburban streets will fall in love with our new truck without realising it,” Mr Cunningham said.
Commercial vehicle manufacturer Scania has teamed up with Swedish waste company Renova to develop a fuel cell powered refuse truck with a fully electrified power train and compactor.
The two companies aim to reduce emissions and noise to make the electrified vehicles an attractive alternative when working in residential areas at early hours of the morning.

- Waste fleet adds hybrid electrics
Renova and other waste handling companies have previously carried out trials with electric refuse trucks, however this will be the first with fuel cells.
Scania Electric Powertrain Technology Project Manager Marita Nilsson said the company is highly interested in gaining more experience of fuel cells in actual customer operations.
“Fuel cells constitute a promising technology in the needed decarbonisation of transports,” Ms Nilsson said.
Renova Head of Development Hans Zackrisson said electrification using fuel cells fuelled by hydrogen is a highly appealing alternative for heavy commercial vehicles such as refuse trucks.
“The trucks benefit from all the advantages of electrification while maintaining some of the best aspects of fossil-fuel operations, namely range, hours in service and payload,” Mr Zackrisson said.
Scania has also previously partnered with Norwegian food wholesaler Asko to develop hydrogen fuel cell technology for its production plant.
The project is being implemented in cooperation with the Swedish Energy Agency and Stockholm’s Royal Institute of Technology. The fuel cell refuse truck is expected to be delivered in the end of 2019 or by the beginning of 2020.
