4.9.5 Recycling Collection Fuel Use Recycling collection efforts essentially are duplicates of MSW collection efforts. In some instances as with automated single -stream recycling collection, the vehicles involved are used for both collections. If the collection vehicle is dedicated to recycling collections only, with the load weights involved with recycling being less than garbage, the necessary horse power and torque requirements can be less than MSW vehicles. Solid waste industry vehicles are all heavy duty in nature and their fuel consumptions are significant. Lowering the horse power and torque requirements of recycling collection vehicles 10-25% doesn't necessarily lower fuel consumption by a linear amount. As discussed earlier, this report addresses the relational nature of fuel consumption. Therefore the assumption for fuel economies will be the same for recycling collection activities as was used for MSW services. As presented in the MSW collection portion of this section, the factors involved with distances between stops and the distances between households serviced will be presumed to be identical in that all communities require haulers to provide recycling services (except St. Paul who contracts with a single hauler for recycling collection). Although these services are provided, not every household will participate in every collection. This is also the case for the MSW collection activities. Without having the ability to determine setout rates for either service, the assumptions will be that every household sets out materials at every opportunity. Eagan In order to demonstrate the relationship of fuel consumption for the recycling collection services, the system in Eagan is displayed in two different ways. The current system has differing levels of collection frequencies not all of which were fully determined by the data collection process. The two tables for the city of Eagan display the data as though the entire city is collected on an every other week basis. Doing so tends to minimize the projected fuel use (i.e., provide a sort of "best case" for the existing system fuel use). Table 4-19 models the existing Eagan recycling collection system based on all households collected every other week with a 15 second loading time per stop. The fuel consumption factor for this analysis shows that 216% more fuel is projected to be used in the existing system than in a projected organized system with every other week collection and 15 seconds loading time. The difference is solely attributable to the market share percentages of the existing system versus a 100% market share for an organized system with the same collection parameters.
