Abstract

As environmental sustainability becomes a key consideration in policy-making, more responsible consumption and utilization in daily life concern both health and quality of life. To address inequities in health in relation to environments, waste management has taken more progressive ways, and one of them is biomass-to-energy conversion that utilizes energy recovery from food waste. By extension, a food waste zero-emission system using fermentation and extinction technology gains much attention, so that this study is designed to examine residents' attitudes toward recycling food waste produced at home and toward food waste zero-emission system. Utilizing a survey questionnaire, this research collected data from 400 individual units of multifamily housing estates nationwide, and the data were analyzed using descriptive and inferential statistics. The findings indicate that food waste generated at home was highly water-contained and produced in the stage of food preparation before cooking while respondents viewed that food waste collection and treatment needed to be improved. It's noted that respondents strongly supported the use of food waste as a energy source and would have the use of the food waste zero-emission system built in kitchen sink. Regression analysis showed that educational attainment of housewives, cooking style, and planning food purchase were statistically significant factors in the attitude of the responded residents toward recycling food waste while none of the factors were in the attitude toward the food waste zero-emission system.

주택 내에서 발생하는 음식물 쓰레기의 실태를 조사하고, 음식물 쓰레기의 자원화와 바이오처리를 이용한 음식물 쓰레기 무배출 시스템에 대한 거주자의 태도를 조사하는 본 연구에서는 전국 소재의 공동주택 단지 총 400세대를 대상으로 설문조사를 실시하였다. 가설검정을 위하여 SPSS window version 18.0 통계분석 프로그램을 사용하여 빈도 및 백분율, t-검정, ANOVA, 요인분석, 로지스틱 회귀분석을 실시하였다. 분석 결과, 주택에서 배출되는 음식물 쓰레기는 국 또는 찌개류, 나물반찬, 과일류 등 수분이 다량 함유되고 쉽게 부패되는 종류였고, 음식준비과정에서 많이 배출되고 있었으며, 쓰레기 배출시 악취와 벌레 등의 불쾌감과 쓰레기 배출시의 불편함이 지적되었다. 이로 인해 음식물 쓰레기의 에너지화와 부엌 싱크대에 음식물 쓰레기 무배출 시스템의 설치에 적극적이었으며, 그 시스템을 주택건설단계부터 구조적으로 설치되길 선호하였다. 회귀분석 결과, 주부 학력, 요리스타일과 식재료 구입계획의 식재료 구매단계 특성이 음식물 쓰레기의 자원화 경향에 통계적으로 유의한 요인들이었다. 즉, 주부 학력이 높을수록, 식재료 구매단계특성 중 식재료 구입계획이 허술할수록 음식물 쓰레기를 자원화하려는 경향이 높았다. 반면, 음식물 쓰레기 무배출 시스템 설치 희망에 미치는 요인은 통계적으로 유의하지 않았으나, 주부연령이 낮고 학력이 높을수록 가족생활주기가 자녀초등 청소년기일수록 음식물 쓰레기 무배출 시스템 설치를 적극적으로 희망하는 편이었다. 따라서, 쾌적한 주거환경 조성과 지속가능한 생활환경 창출을 위해 음식물 쓰레기의 자원화 및 무배출 시스템의 설치는 필요하며, 활발한 보급을 위해서는 사용자 친화적인 설계와 제도적 지원이 수반되어야 할 것이다.
