CURBSIDE COLLECTION OF YARD WASTE: II. SIMULATION AND APPLICATION

Curbside collection of yard waste can be prohibitively expensive due to the inherent costs of curbside collection and the small amounts collected compared to the total waste stream. The authors of this paper use a simulation model to investigate the effect of collection method and route characteristics on route time. Simulation analyses reveal that route time (RT) varies almost linearly with set-out rate (SOR)--the percentage of residences placing materials out on a given day. Route time per unit (RTU) of material collected remins relatively constant for higher SORs, but increases rapidly as SOR decreases below a given point. The characteristics of the collection technique and neighborhood can signficantly effect RT and RTU. However, set-out distribution seems to have little effect over a SOR of 5 percent. Thus, a simple technique for estimating route time is presented, which coupled with a method for predicting collection needs, can be employed to predict vehicle and labor requirements for compost curbside collection programs.
