Abstract
This research conducts both experimental evaluation and resident's assessment of zero food waste system (ZFWS) in multifamily housing estates in order to explore the feasibility of ZFWS embedded in fermentation and extinction technology utilizing wood chips turned into fertilizer. Having been established in a multifamily housing estate, ZEFWS was proved to be functional and effective. During the 3-month experimental period, the weight between infused food waste and its reactor was reduced significantly enough, and the chemical analysis showed that the concentration of organic compounds went from 87.9% to 75.8%, $H_2O$ decreased from 69.7% to 45.5%, NaCl rose from 0.2% to 0.5%, pH increased from 4.6 to 7.8, and ATP escalated from 505.3 nmol/L to 723.5 nmol/L. Also, the chemical analysis of the output in the experimentation indicated adequacy of the organic fertilizer. In the self-administered questionnaire survey for residents participating in the field project, almost all the respondents viewed that ZFWS can compete with conventional food waste disposal methods and an idealistic way to upcycling food waste into fertilizer.
