Republic operates a fleet of more than 1,400 CNG vehicles and 26 natural gas fueling stations nationwide. Approximately 50% of all Republic vehicles purchased in 2013 are powered by the domestic fuel source. It plans to have more than 3,100 trucks nationwide running on natural gas and other alternative fuels by the end of 2015. At press time it announced it’s deploying 53 CNG solid waste and recycling trucks to serve customers throughout the Charleston, S.C., metro area.RRR Transportation
The majority of this 135-truck fleet features 2013 and 2014 trucks with the Volvo XE efficiency package. Transtex trailer fairings and ATDynamics Trailer Tails are on the trailers, and Anderson Flow through mudflaps are on tractors and trailers. Older reefer units are being replaced with Thermo King Precedent Units with electric shore power. In addition to diesel electric APUs, this year RRR added an electrical grid at its terminal for shore power and reefer standby. It uses electrified truck parking when possible to avoid running the diesel APU, and is adding PeopleNet to better monitor drivers and optimize routes.
Ruan Transportation Management Systems
Des Moines, Iowa
This 2012 SmartWay Excellence Award winner runs 3,900 vehicles, including 44 heavy-duty CNG. It says its CNG fleet servicing an Indiana dairy client is the largest in the nation. Biodiesel emissions are reduced by 86% compared to petroleum diesel. Auxiliary power unit usage reduces engine idle time. Lighter weight equipment, aerodynamics, automatic tire inflation systems and low-viscosity lubricants are among the technologies that improve fuel consumption, along with reduced standard highway speeds and driver training. Beyond the truck fleet, Ruan has seen a 99% reduction in paper in communicating between its corporate and field offices since 2007, uses low-environmental impact solvents and materials and has LEED-certified buildings.

This fleet of 287 has been an early adopter of a number of aero technologies. It was the first to install Utility’s new side skirts on their 2011 trailers, and now has trailer skirts on the entire fleet. After evaluating ATDynamics TrailerTails through a program managed by the Department of Energy, it decided to launch a fleet-wide retrofit program. It uses fuel-efficient tires on the entire fleet and has an mpg bonus program for drivers. Using IdleAir has saved the company more than $45,000 so far this year by cutting idling.
Staples has improved its fleet average mpg by 30% since 2005, on its way to a goal of 40% by 2015. Out of its 15 Class 7-8 trucks and tractors, 10 are CNG. The bulk of its trucks, more than 1,700 of them, are in Class 3-6. They all use biodiesel, plus there are 53 electric and 20 flex fuel. All trucks are controlled to a top speed of between 58-63 mph. Idle is limited to 3 minutes unless certain temperature or operating conditions are met. The 53 Smith all-electric first generation trucks have been in service since 2010, and five new next-generation models are set for delivery in January. It’s also working with Roush Clean Tech and Ford for LPG F-550 rated at 19,500 pounds as a potential flagship truck for Staples delivery.
