摘要
Lower birth rates and spoiling have caused students to become picky eaters, leading to campus food waste. In this study, 29 evaluation indicators for a black soldier fly biological system were established through a literature review and expert interviews. The indicators were divided into three dimensions, namely spatial composition, system and equipment, and environmental education. The 11 indicators with the highest expert consensus were identified through the fuzzy Delphi method and used as the primary indicators for evaluating the role of the black soldier fly biological system in promotion. The top 11 indicators with the highest scores mostly comprised indicators of the system and equipment dimension followed by those of the spatial composition and environmental education dimensions. However, among the indicators of the three dimensions, those of the "spatial composition" dimension obtained the highest scores. The literature review indicated that the theories related to knowledge, behavior, and attitude toward the environment should be applied to consciously motivate students to reduce food waste through explicit actions. The integration of the aforementioned system with experiential agricultural education can reduce campus food waste. Participatory learning increases the willingness of students to improve appropriate environmental attitudes and healthy diets on the basis of promoting environmental sustainability.
