Instruct the loader operator to capture recyclable materials from two randomly <br />selected cells in the grid - one from the top half of the load and one from the <br />bottom balf. These two cells should be randomly selected prior to sampling using <br />a random number generator. The desired cell numbers should be written on each <br />load's data sheet (see Attachment C). <br /> <br />3. Mix the recyclable materials extracted from the two cells on a hard, flat surface. <br />Instruct the loader operator to mix the recyclables so as to distribute the various <br />materials throughout the pile (i.e., first mix the recyclables back and forth in one <br />direction, then take recyclable materials from a cross-section of the pile <br />perpendicular to the mixing direction) to ensure a representative sample (see <br />Figure 2 below). <br /> <br /> <br />~ I Extract Sample for Sorting <br /> <br />Figure 2 - Mixing and Extracting Waste <br /> <br />I The number of cells in this grid can be adjusted downward for small loads. For example, a small load <br />can be divided into eight cells instead of 16 to ensure that a sufficient amount of recyclable materials <br />(between 200 and 300 pounds per cell) is captured for sampling. <br /> <br />B-4 R.
