Soil-Equivalent Foam as ADC on Balefills
However, unlike the sloped face at a typical conventional landfill, the vertical wall of a balefill requires a unique solution for daily cover.
Soil is not a viable option because of the large amount required and the need to remove it the following day to restore the vertical face before placing additional bales. Tarps can present problems with deployment, retrieval, odor sealing, safety, and wind.
The Monmouth County Reclamation Center (MCRC) in Tinton Falls, NJ, had been using the Rusmar self-propelled foam system as an ADC for a few years before converting to a balefill in 1997. Leading up to the conversion, John Gray, superintendent at MCRC, and his staff worked closely with Rusmar to develop a foam that would adhere to the vertical working face, meet all other ADC requirements, and maintain the user friendly characteristics of the foam application system.
The solution was the special formulation—AC-667SE Soil Equivalent Foam—and the customized 1600/40 Pneumatic Foam Unit.
MCRC and Rusmar removed the foam unit from the standard trailer and mounted it on a U.S. Army surplus chassis. An operator platform and fire-fighting monitor were added at the rear.
The truck drives along the base of the working face and the operator "spray-paints" the foam onto the exposed bale faces. The entire operation takes about 30 minutes at this 1700-tpd facility.
The foam consumes no airspace and does not require removal the following day. No equipment clean up is required nor is it necessary to use all of the foam on a given day. The equipment is freeze-protected for outdoor storage year-round. No other equipment at the landfill is required and the foam system is an excellent supplement to MCRC's fire-fighting apparatus.
