Where CDF capacity is diminishing, volume reduction of incoming material might seem to be

indicated in all cases (Figure 2). However, the benefit will be dependent upon the nature of the

incoming material and the amount of volume reduction to be derived compared to the processing

cost incurred. In cases where the incoming material is not suited to volume reduction, then removal

of previously placed materials to recover in-CDF capacity might be another option, depending upon

the nature of the materials previously placed (Figure 3). Where both incoming and previously placed

materials lend themselves to volume reduction, the third alternative could be implemented

(Figure 4).
