Mack Trucks…worlds cleanest concrete mixer
Friday, September 4th, 2009*The New Breed Granite, installed with a Cummins Westport ISL-G gas engine, is the world’s cleanest because it is the only concrete agitator that reduces particulate matter (soot) by 92% and nitrous oxides by 90%, compared with current Australian legislative requirements (US04)1.
In fact, it is the first concrete agitator to meet US EPA 2010 emission levels, not expected to be a requirement in Australia until 2016.

The truck was commissioned by Boral as the next generation of Hippy Trucks – powered by natural gas.
Dean Bestwick, General Manager Mack Trucks, said this world-first achievement started out as a desire by Boral to provide the next generation of environmentally friendly gas trucks – thereby establishing a strategic leadership position for both companies.
“Engineered, designed and built in our Australian factory at Wacol, this highly productive heavy-duty concrete agitator, boasts a globally unequalled exhaust emission output. It’s testament to our local innovation and engineering capability,” he said.
Shane Graham, Boral’s General Manager, ACM Concrete, said the truck has just finished a four week trial in Sydney where it matched the carrying capacity of the other vehicles in the fleet and has already proven to be a cost effective transport solution.
“We are committed to a sustainable environmental strategy, and to reducing our reliance on diesel. With five CNG tanks that provide a full day’s operating range, this truck has demonstrated that we can achieve both without compromising our rigorous operational production requirements,” he said.
