"Forty-five landfills and associated transfer stations, balers, shredders, and transportation networks were analyzed to determine costs for building and operating a landfill and to identify the factors that have the greatest impacts on those costs. The landfills studied ranged in size from under 100 to more than 5000 tons per day and were located across the continental United States. A primary concern of the study was to determine whether failing or shredding reduced landfill costs. Analysis incurred at the landfill, due to prior bailing or shredding, usually does not compensate for the added cost of these more sophisticated processing facilities for the average case. On the other hand, baling or shredding might be feasible in a situation where component costs for the entire landfilling system are high. Another important finding is that landfilling is only a small portion of total costs. On the average, both the haul and the processing components of the system are more expensive than the landfilling component."
