SECTION 2 <br />Countywide Sampling Results <br />This section presents a summary of countywide composition results for the total waste <br />stream and the three substreams (transfer stations, commercial, and self - haul), and includes <br />data for both West and East Hawai'i. Most of this information is presented in one of the <br />following two formats: <br />• A bar chart that depicts the composition by nine main waste categories: paper, glass, <br />metal, plastic, organics, construction and demolition, household hazardous, special, and <br />mixed. <br />• An exhibit that lists the ten largest of the 58 waste components, by weight. <br />More comprehensive exhibits that details the full composition results for the 58 component <br />categories are presented in Attachment A (Exhibits A -1 through A -6). <br />2.1 Total County, West Hawaii, and East Hawaii Composition <br />Exhibits 2 -1, 2 -2, and 2 -3 are bar charts that show the overall composition results for the nine <br />main waste categories of waste disposed for the entire County, for West Hawai'i, and for <br />East Hawai'i, respectively. When combined, organics and paper comprise more than half of <br />the waste stream. Construction and demolition waste accounts for another 22% by weight. <br />The construction and demolition category includes such components as clean lumber and <br />gypsum scrap. The organics main waste category contains such components as food, <br />textiles, and prunings. <br />The composition of waste disposed in West Hawaii is similar to the composition of <br />disposed waste in East Hawai'i. Two differences that merit mention include: there are more <br />organics disposed of in West Hawaii (35.3 %) than in East Hawaii (29.6 %); and more special <br />waste disposed of in East Hawai'i (5.2 %) than in West Hawai'i (1.9 %). The types of special <br />wastes disposed most often in East Hawai'i include industrial sludge, bulky items, and tires <br />(see Exhibit A -3 in Attachment A). <br />Exhibits 2 -4, 2 -5, and 2 -6 show the ten largest waste components for the entire County, for <br />West Hawai'i, and for East Hawai'i. In all three areas, the largest three components by <br />weight are food, clean and treated lumber7, and cardboard, which combined make up <br />approximately a third of the total waste stream. <br />Notable differences between West Hawaii and East Hawaii include: <br />• One component in each area appears on the list in one area but not in the other: <br />R/C meta18 is in the top ten for West Hawai'i, and film plastic in East Hawai'i. <br />7 Most of the disposed lumber in the waste stream is treated, and is not appropriate for composting <br />8 The R/C components include waste that is made mostly of one component but contains significant amounts of other <br />components, or waste that is part of a broad waste category but cannot be put into any of its component categories. Examples <br />of R/C organic waste includes carpet and disposable diapers, while materials such as paper towels and coated milk cartons <br />belong to R/C paper. <br />APPX B WASTE COMPOSITION REPORT 121709.DOC 2 -1 <br />
