<br /> 2.5 Problems Encountered and Lessons Learned <br /> Information and data presented in this section were taken from published data from <br /> KRRC contractors and vendors, from a limited traffic survey conducted by Recycle <br /> Hawaii, from a limited user survey conducted by RCAC, and from interviews with key <br /> persons conducted by RCAC. <br /> 2.5.1 Contamination. Contamination was a problem from the beginning, although it <br /> decreased with customer education efforts, improvements in signage, and <br /> increased staffing at KRRC. Contamination included: <br /> • Plastic bags, metal, and tires in the greenwaste bin. <br /> • Plastic bags in the plastics bin. <br /> • Motor vehicle parts containing used motor oil and other fluids in the scrap <br /> metal bin. <br /> • Bags of rubbish leR adjacent to recycling bins because people did not want to <br /> stop twice to unload. <br /> Paying the full tip fee on contaminants removed from recycling bins was a <br /> hazdship for vendors contracted to remove the materials from KRRC. Vendors <br /> had little or no control over the level of contamination in any given bin. Also, the <br /> level of contamination in bins varied widely and could not be predicted by <br /> vendors when they prepazed cost proposals to Recycle Hawaii. This is a difficult <br /> issue, especially in a dropoff environment, but one that must be resolved if the <br /> County intends to rely on private vendors to service its recycling centers. <br /> 2.5.2 Education. Educational workshops for adults were successful. Activities for keiki <br /> were less successful, perhaps because the site environment with its heavy traffic <br /> was not suitable for children. Jay West suggested that more workshops be offered, <br /> and that workshops could be a potential source of revenue. A permanent <br /> education center more remote from dust and noise sources such as traffic would <br /> enhance KRRC's ability to draw workshop participants. <br /> Due to liability issues, Recycle Hawaii was constrained by contract from <br /> allowing outsiders to sponsor events at KRRC, so was unable to meet demand for <br /> more workshops. KRRC appears to have potential for becoming a community <br /> focal point and gathering place for environmental activities and education, given <br /> proper facilities. It may also have potential as a cottage industry incubator site. <br /> Signs created by Jay West helped considerably with customer education by <br /> instructing people as to how and where to recycle various materials. Nelson Ho <br /> recommended more signs, specifically focusing on the why of recycling. <br /> The temporazy workshop azea was not secure enough. Some customers removed <br /> art work and workshop materials, appazently thinking they were free for the <br /> taking like items in the adjacent reuse center. <br /> 2.5.3 Eauiument. Several equipment problems/needs were noted: <br /> • Lack of spaze or backup bins resulted in bans on dumping materials for <br /> approximately four hours whenever a full bin was hauled out. <br /> 10 <br /> <br />
