Comparing the tonnages collected before and during the pilot: The single-stream routes resulted in statistically significant increases in total tonnages recovered, even when their relatively high portions of non-targeted materials were subtracted out, as compared to the same areas collected as dual- stream routes in the "Before" period. The Larger Bin Capacity route resulted in a statistically significant increase in total tonnage recovered, net of non-targeted materials, as compared to the same area collected in the "Before" period. Table ES-2 compared the pilot routes in which the recyclable materials were collected every other week. Because the Tuesday pilot route was collected weekly, the pounds collected per household were not comparable to those collected every other week, so a comparison of the weekly routes was conducted separately. During the pilot, the average gross pounds of recyclable material collected per household on the weekly route was 14.95 pounds. The average pounds of non- targeted materials per household was .55 pounds per week, resulting in the net pounds per household per week of 14.40 pounds. The effects of weekly collection of recyclable materials can be compared to every other week collection on an annual basis. Table ES-3 below shows the projected annual pounds per household for each route, based on the average pounds collected per collection event during the pilot, net non-targeted materials.
