Mack Trucks unveil world’s cleanest concrete mixer

(Sydney, Australia) — Mack Trucks’ New Breed Granite, installed with a Cummins Westport ISL-G gas engine, is the world’s cleanest concrete mixer because it is the only concrete agitator that reduces particulate matter by 92 per cent and nitrous oxides by 90 per cent compared with the current Australian legislative requirements.

It is also 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.

Shane Graham, Boral’s general manager, ACM Concrete, said that 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.
