Waste Management Launches First Rotopress Collection Vehicles

Waste Management, Inc. (Houston, TX) plans to roll out its first Rotopress collection trailers, which have been available in Europe for nearly eighty years, in an effort to improve operational flexibility and reduce fuel use and lower maintenance costs. The Rotopress trailer, built by German company Faun, employs a corkscrew method to compact waste which increases payloads by about 40 percent. A typical trailer can hold 14 tons compared to 10 tons for a conventional vehicle. It features a “decoupled tractor-trailer configuration” that gives the vehicle a tighter turning radius, among many other benefits. The company says the ability to decouple the trailer from the chassis will offer more maintenance flexibility, leading to better utilization of assets. Moreover, the unique corkscrew design moves waste to the front of the body which better distributes the weight over both axles leading to improved performance and lower maintenance costs.

Waste Management Launches First Rotopress Collection Trailers to North America
Innovative technology to provide greater flexibility and reduce trips, fuel use, greenhouse gas emissions and improved maintenance costs.
Waste Management, Inc. (NYSE: WM) announced today a pilot program that will introduce Rotopress waste collection trailers for the first time in North America to improve the flexibility of its waste collection operations.
The pilot program will first rollout in Houston, Texas, followed by pilot projects in San Diego, Calif., Sacramento, Calif., Milwaukee, Wis. and Camden, N.J. One of the new pilot vehicles will be unveiled at the company’s headquarters in Houston, Texas today. Waste Management anticipates the program to provide greater operational flexibility and reduce trips, fuel use, greenhouse gas (GHG) emissions and improved maintenance costs.
The Rotopress modular technology, combined with a decoupled tractor-trailer configuration using natural gas as its fuel source, provides a number of operational and environmental benefits to meet the challenges of a diversifying waste stream, reduces capital costs, reduces exposure to rising fuel prices and reduces vehicle emissions.
Decoupled Chassis: The decoupled tractor-trailer configuration allows for better management of assets as chassis and body can be replaced separately on a more effective schedule. In addition, these assets are decoupled, which allows for future, fuel-saving class 6 tractor operations, which will operate on natural gas.
Ease of operation: Compared with a rigid vehicle, a semi-truck trailer has a 40% smaller turning radius making it more maneuverable, which is very desirable in residential areas with cul-de-sacs and parked cars and in other tight areas. In the event of a breakdown, the truck and module can be separated reducing downtime and improved utilization of trucks.
Improved maintenance costs: The unique corkscrew design of continuously moving waste to the front of the body will help prevent the rear axles from being overloaded while keeping sufficient weight on the front axle at all times. This makes the drive smoother and reduces wear on tires. The maintenance costs related to the tractor-trailers should be improved as there is less stress on the suspension and far fewer moving parts compared to a conventional rear loader.
No odor or leakage: The Rotopress does not directly press any additional liquid out of the waste, but binds it by permanently mixing it with the dry material. This operation reduces the amount of free liquid in the system, lowering damage to the body that can be caused by corrosion and additionally reducing leakage and odors considerably.
Rotopress, manufactured by Faun, a German manufacturer of waste disposal vehicles, has been in operation across Europe for more than eight decades.
“Waste Management’s investment in unique and innovative fleet technologies like the Rotopress is helping us operate our core business activities more efficiently as well as reduce the environmental footprint of our fleet,” said Eric Woods, vice president, fleet and logistics at Waste Management. “The Rotopress will help contribute toward our corporate sustainability goal to increase fuel efficiency by 15 percent and decrease emissions by 15 percent by 2020. Our plan is to save 350 million gallons of fuel and reduce 3.5 million metric tons of carbon dioxide by 2020.”
The introduction of the Rotopress builds on Waste Management’s existing fleet of more than 1,400 heavy-duty trucks fueled with natural gas and the company’s long-standing commitment to transition from diesel to natural gas trucks and build toward a zero-emission fleet. For every truck Waste Management converts to natural gas, diesel fuel use is reduced by an average of 8,000 gallons and GHG emissions are reduced by 22 metric tons annually, providing significant economic and environmental benefits.
