Mack now offers refuse trucks with the Cummins Westport engine powered by compressed or liquefied natural gas.
LAS VEGAS, Nev. — Mack Trucks has introduced a natural gas-powered version of its TerraPro Low Entry model truck targeted towards refuse applications.
The engine is supplied by Cummins Westport and a cabover version of the truck will be introduced later, Mack announced at the WasteExpo trade show this week.
The 9-litre Cummins Westport ISL G engine is rated at 320 hp and can use either compressed natural gas (CNG) or liquefied natural gas (LNG). It is equipped with a three-way catalytic converter to comply with EPA2010 emissions standards, Mack says.
“We’re bringing the Mack tradition of application excellence to alternative fuel vehicles,” announced Dennis Slagle, Mack president and CEO. “The natural gas products we’ve now brought to market will extend our position of leadership in refuse into this emerging segment.”
Chicago-area waste hauler Groot Industries has already placed an order for 20 CNG-powered refuse trucks, Mack announced. They’ll be put into service by the end of the year.
“Refuse companies these days are expected to be environmental leaders in their communities,” said Brian Curry, director of fleet and facilities for Groot Industries. “We look for ways to serve customers with the cleanest and most efficient trucks available, which is why we were so interested in Mack’s natural gas solution. Our Mack TerraPros will help us reduce emissions and our carbon footprint, as well as lessening the US’s dependence on foreign oil.”
Mack says it has noted an increase in the number of municipalities that have mandated their contractors use alternative fuel vehicles as a condition of their contracts.
“Natural gas has a number of significant benefits,” said Tom Kelly, Mack senior vice-president of product portfolio management. “It burns very cleanly, there is an abundant supply here in North America, and it’s comparable to diesel in terms of cost over the life of the vehicle.”
