Dispersal of 10-14-mesh corncob granules in stacked tires.
Dispersal of 10-14-mesh corncob granules was evaluated in 2 random-stacked tire piles, one shingle-stacked tire pile, and one column-stacked tire pile located in a used-tire storage facility in Chicago, IL. Ninety percent and 98%, respectively, of the tires in the 2 random-stacked piles contained granules. In the shingle-stacked tire pile 87% of the tires sampled contained granules, and the number of granules per tire was dependent on depth. The 2 bottom rows of tires were 73.9% less likely to contain granules than the 5 rows above them. In the column-stacked tire pile 91.2% of the tires contained granules and the relationship between granule recovery and tire depth was logarithmic. Overall, the dispersal of 10-14-mesh corncob granules was comparable to that of 8-mesh corncob granules evaluated in a previous study at this site.
