Using a significant database of origin postcodes, a study was designed to estimate the current annual mileage associated with visitor trips to household waste recycling centers (HWRCs)—known as manned recycling drop-off centers in the United States—and to identify how this mileage could be reduced if a series of "bring sites" (unmanned recycling drop-off centers) in the community were enhanced to take green garden waste. The total annual distance driven by approximately 4,677,000 visitors to the 26 HWRCs in Hampshire, United Kingdom, is estimated to be 40 million kilometers (assuming that 60% of visitors made dedicated trips), costing approximately £14 million (£1 = $1.896 in April 2005 U.S. dollars) in private transport and emitting approximately 1,873 tonnes of CO2 (as carbon) into the atmosphere. Providing a network of 104 bring sites capable of accepting green waste, in addition to the existing facilities provided by the 26 HWRCs, could save approximately 8.5 million kilometers (21%) of vehicle travel per annum (£3 million in visitor transport costs and approximately 369 tonnes of CO2 as carbon). Such a scheme would require a fleet of approximately 78 refuse collection vehicles at an annual cost to the scheme provider of slightly more than £1.5 million. If HWRCs become a major channel for the return and reprocessing of waste electrical and electronic equipment and some newly classified hazardous waste items, space at existing sites could become an issue. More local consolidation of certain waste categories (e.g., green waste) would enable HWRCs to focus their activities better.
