B. A visual audit was conducted of construction and demolition (C&D) debris and other bulky wastes delivered to the County's landfill. This waste stream also contained a substantial amount of materials that have the potential to be recycled, including rock/gravel (26.3%), yard trash (14.9%), untreated wood (11.9%), drywall (14.1%), corrugated cardboard (1.8%), carpet and padding (1.6%), rigid plastics (1.4%) and scrap metals and appliances (1.2%). TM5 identifies options and opportunities related to the County's solid waste collection and recycling systems that can help the County maximize recycling, lower costs, and/or enhance efficiencies. A. Collection Opportunities: Based on an analysis of the County's existing collection system, KCI developed the menu of options provided in Table 2 that seek to increase collection efficiency and thereby lower rates, modernize the collection system, and increase recovery of recyclables. Options may be considered independently, but provide greater opportunities in combination with one another. A discussion of each is provided in TM5 and will be discussed in the presentation to the Board. 1. Joint County -municipal collection agreement 2. Curbside collection service options a. Conversion to carted single stream recycling b. Conversion to carted garbage collection c. Use of Radio Frequency Identification (RFID) d. Conversion to weekly garbage collection 3. Universal collection in all of the unincorporated County or in an Urban Service Area 4. Possible closure of one or more CCCs 5. Limit CCC use to County residents only B. Current Waste Diversion and Recycling: KCI estimates that 44% of waste generated in Indian River County in CY 2013 was diverted from disposal. However, based on State rules for determining recycling rates, the County's 2013 recycling rate is calculated at 34%. The primary difference between the two figures is the 32,246 tons of vegetative debris processed by INEOS. Although diverted from disposal, the renewable energy credit received is based on the megawatt -hours generated, which equated to 892 tons. C. Recycling Opportunities: Based on the County's CY 2013 data and WCS results, Figure 1 depicts the types of potentially recoverable materials that are still being disposed, as well as the system changes that would assist in diverting more of these materials from disposa1.1 If all of the recyclables and yard trash accepted in the County's existing programs were diverted from disposal, the recycling rate would be increased by approximately 19%. However, implementing all of changes to the existing program 1 The percentages in Table 1 and Figure 1 differ because those in Table 1 apply only to the residential and commercial waste stream, while Figure 1 includes all waste generated in the County, including C&D debris, yard trash sent to INEOS, and special wastes such as asbestos and industrial waste.
