33 The case examples for this synthesis highlight effective solid waste management strategies at commercial service airports. Information was collected about practices that have become some- what standard and about innovative and state-of-the-art approaches to reduction, diversion, recycling, composting, and disposal. Twenty commercial service airports agreed to contribute a case example, and representatives from each of these facilities participated in phone interviews. One airport did not participate in the first survey but did contribute a case study. In addition, a representative from Snohomish County participated in a case example interview and provided information about the county’s facility. Snohomish County Airport – Paine Field is currently a general aviation facility and is planning for a future passenger terminal. Information collected from Snohomish County is included here to serve as a comparison to the commercial service facilities and as a reference for other general aviation airports. The organizations and airports participating in the case examples are listed in Table 4 by hub size and three-letter identifier. The table gives an overview of the characteristics of each case example airport and lists notable effective program elements. These elements may also be practiced by several other airports and are in addition to baseline practices such as recycling in terminals and employee areas. The full case example program descriptions are included in the appendices, which can be found at http://www.trb.org/acrp/acrpsynthesis92.aspx.
