摘要

Informed multi-family dwelling (MFD) waste reduction and recyclables collection programs require empirical knowledge of the composition, variability, and generation rates of recyclables associated with the waste disposal behavior of MFD residents. A full sampling of MFD residents' non move-out, non-bulky disposal over four study periods was undertaken at a 28-unit apartment complex having no children in Fayetteville, Arkansas. Generation rates for commonly collected categories of recyclables were calculated based on the results of the test for significant difference between period means. Using analysis of variance and a 10% significance level, no significant difference was found between the period means for corrugated boxes, rigid pa-perboard, mixed paper, HDPE bottles and jugs, steel cans and lids, aluminum cans, and clear glass constituent recyclable material groups. Significant differences were, however, found between the period means for newspaper, PET bottles and jugs, the glass material group brown glass, green glass, and total recyclable disposal. The period average total recyclable generation rate ranged from 1.97 kg/person/wk to 2.77 kg/person/wk across the periods. Fifty-two percent of the average resident's generated weekly solid waste was recyclable- an amount that would likely have been noticeably higher had cats not been permitted. Implications for future MFD waste characterization studies are discussed.
