Reducing Environmental Impact in the Waste Industry

Reducing Environmental Impact in the Waste IndustryAs fuel costs continue to rise and vehicle emissions standards grow increasingly stringent, both municipal and private fleet managers must find new ways to contain operating costs by increasing the efficiency of their operations.

It is also evident that virtually every company serving the waste collection and processing industry is committed to their obligation to act as environmental stewards throughout their operations and in their products.

Parker shares this focus and is partnering with its customers to develop and implement new products and systems which will help the waste industry achieve their environmental and sustainability goals.

Innovative coating to extend cylinder life

Reducing Environmental Impact in the Waste Industry - Global Shield CoatingParker’s Global Shield Coating is a new exclusive plating technology available from Parker. When applied to cylinders used throughout the waste industry, whether on refuse collection vehicles or industrial recycling or shredding facilities, the Global Shield coating provides extended cylinder life in abusive environments without the negative environmental impact that occurs with hexavalent chromed solutions.

Global Shield coating provides up to eight times the corrosion resistance of a traditional nitride or chrome coating, reducing the total cost of ownership.

Electronic flow control increases responsiveness and efficiency

Parker’s Intelligent Flow Control (IFC) system architecture is applicable to both mobile and industrial motion and control applications. IFC utilizes electronic displacement controlled pumps, available from Parker, in conjunction with multiple valve designs to provide significantly faster system response to improve productivity, often by 15-20%, while reducing parasitic losses experienced in open center systems or in the form of margin pressure savings in load-sense systems.

Advanced series hybrid drive reduces fuel consumption and emissions

RunWise is an advanced series hybrid drive system with brake energy recovery. The brake energy recovery system converts the vehicle’s kinetic energy into stored energy by compressing nitrogen gas in a storage device called an accumulator. This stored energy is then released during acceleration to reduce the energy required from the engine to propel the vehicle.

Reducing Environmental Impact in the Waste Industry - RunWise System Parker HannifinThrough the series drivetrain architecture, the engine can be operated at speeds independent of vehicle speed. As a result, the engine always operates at the ideal spot for any power level demanded by the vehicle operator, which can be a limitation of a conventional transmission.

By reducing energy demand, RunWise reduces fuel consumption, regardless of fuel source, by 35 to 50 percent, depending on route density and operating conditions. A truck equipped with RunWise hydraulic hybrid system can consume 4,300 gallons less fuel per year than a truck utilizing a standard transmission. This equates to an average annual reduction in CO2 emissions of 48 tons per year, equivalent to removing 10 midsized cars from the road or planting 1,100 trees and letting them grow for 10 years.

In addition to reducing fuel consumption and emissions, Parker’s brake energy recovery technology lengthens the brake replacement cycle to one or two brake jobs throughout the life of the truck (depending on duty cycle), dramatically reducing maintenance costs as well as the disbursement of brake dust into the atmosphere. By improving acceleration and braking, RunWise can also reduce collection times by 1-2 hours.

Technology to protect the environment and improve the bottom line

Parker is committed to maintaining its leadership in advancing motion and control components, systems and technologies with focus on improving its own environmental footprints as well as assisting its customers and served markets in achieving their environmental goals.
