California city replaces diesel fuel with natural gas powered fleet
In 2012, the City of Pomona, California purchased 22 natural gas-powered MACK TerraPro Low Entry vehicles, converting its entire fleet to alternative-fuel technology.
“The City of Pomona is committed to reducing its environmental footprint,” said Howard Morris, Pomona Solid Waste manager. “We liked what Mack had to offer, especially its excellent reputation and the durability and reliability of its products.”
The natural gas-powered TerraPro refuse vehicle combines the advantages of domestically produced natural gas with the power and torque customers have come to expect from Mack. In creating their new all-Mack natural gas-powered fleet, the City of Pomona ordered 20 TerraPro Compressed Natural Gas (CNG) side-loaders and two rear-loaders. The City worked with Dan Huntsinger at TEC Equipment, Inc., La Mirada, California, to complete the purchase.
“Refuse is an ideal application for natural gas because these trucks return home each day for refuelling,” said James Waterbury, Mack Pacific District sales manager. “The natural gas powered Mack TerraPro refuse vehicles offer an alternative domestically sourced fuel in a durable truck.”
Mack offers natural gas power, in both their MACK TerraPro Low Entry and MACK TerraPro Cabover refuse models. Units feature maintenance-free aftertreatment and require only a three-way catalyst to meet EPA 2010 and CARB emissions standards, which according to Mack, sets a new benchmark for lower lifecycle costs in alternative fuel vehicles. Mack’s natural gas-powered trucks are available with compressed (CNG) or liquefied (LNG) fuel systems.
“Mack has a long history in alternative driveline technologies, and in particular, natural gas,” said Kevin Flaherty, president, Mack Trucks North American Sales & Marketing. “We’ve offered natural gas since it became clear that it was a viable energy solution in the refuse segment.”
Mack says they are also investigating other alternative driveline technologies, including high pressure direct injection, which uses a combination of natural gas and a small amount of diesel in the combustion process, and DME (dimethyl ether), which can be produced from natural gas. In addition, the company continues to move forward on development of diesel-electric hybrid TerraPro models, recently delivering additional Low Entry test units to the New York City Department of Sanitation for evaluation.
“For more than 35 years, we’ve counted on Mack for trucks that can withstand the tremendous rigours of our operations,” said Rocco DiRico, deputy commissioner, Department of Sanitation, Support Services, New York City. “We look forward to putting these new vehicles with the latest version of Mack’s diesel-electric hybrid technology to the test.”
Mack says their diesel-electric hybrid technology provides up to a 30 percent fuel economy improvement in stop-and-go applications such as refuse and recycling, with a corresponding greenhouse gas emissions benefit.
