. .... .. .... ... .......... <br /> i <br /> The calculations below illustrate estimated savings that are projected annually from the Walnut <br /> Grove Church Road convenience center compactors based on the first approximate ten months <br /> of operation. These calculations can help to justify the purchase of new compactors based on <br /> the experience compactors have provided in improved efficiency and effectiveness. <br /> i <br /> At Walnut Grove Church Road Convenience Center,the corrugated cardboard was previously <br /> collected in ten eight-cubic yard containers three times a week. This equates to 240 cubic yards <br /> a week hauled an average distance of 23 miles to market. Under the use of the new { <br /> compactor,that same load is hauled once a week in a container that has been loaded using a i { <br /> compactor. The compactor saves 2,400 road miles a year or an estimated 600 gallons of diesel <br /> fuel assuming an optimistic 4 mpg for hook lift trucks. At an average trip time of about 30 <br /> minutes one way,plus dumping time of ten minutes, the hauling time savings are <br /> i <br /> approximately 121 hours per year(or approximately 6%of one employees annual time)that j <br /> could be used on other tasks. <br /> Payloads in previously used un-compacted single stream roll-off containers averaged about 1.9 <br /> tons and containers from the single stream compactor at the Walnut Grove site haul an average I <br /> of 6.5 tons now.Hauling savings from this remote site are significant at 36 miles per round trip. <br /> The single stream containers are pulled approximately two times a week. Doing the calculation <br /> for saved miles and converting to gallons of diesel saved results In an estimated annual savings <br /> of approximately 2,340 gallons. <br /> i <br /> Estimated hauling savings from the nearby Eubanks Road site,where compactors are in close <br /> proximity to the county recycling processing area,is about 300 miles a year(151 trips saved <br /> based on current data for compactor and roll-off tonnages for single stream loads and a total <br /> single stream tonnage from last year at Eubanks site of 405 tons). There would be an annual <br /> estimated savings of 65 gallons of diesel fuel or$255 at a current price for diesel fuel of$3.92. <br /> There is also an unquantiflable savings In safety improvement due to a reduction of 151 trips by <br /> a large truck at a crowded and active site. Labor savings were estimated using 10 minutes total <br /> per trip,including dumping time, resulting in 26 hours of hauling time that can be used for <br /> other recycling efforts. <br /> As discussed above,the new compactors will enhance an already existing service;however,as <br /> illustrated by recycling compactors installed at another convenience center, these new <br /> compactors for the Eubanks Road convenience center will increase program efficiency,save <br /> personnel time as well as costs relating to hauling,fueling and vehicle maintenance,and <br /> improve the safety of recycling customers. <br /> Location: <br /> 1514 Eubanks Road <br /> Chapel Hill, NC 27516 <br /> Orange County 2014 CWRAR Proposal Page 3 <br />
