食物浪费是一个日益严重的全球性问题，具有广泛的环境、经济和社会影响。家庭既是废物产生的主要推动者，也是源头减少和堆肥等解决方案的关键推动者。在美国，家庭食物垃圾仍然主要被填埋，这促使这项研究了解个人在决定是否单独收集家庭食物垃圾作为垃圾填埋场转移的先兆时所面临的信念、经验和障碍。为了理解这些因素，我们利用对纽约州居民的调查收集的数据应用了计划行为理论，并使用结构方程模型进行了分析。结果表明，态度、主观规范和感知行为控制都与分类家庭食物垃圾的意图显着正相关。然而，受访者还表示非常担心食物垃圾分类会导致家中产生异味、害虫和混乱，最终导致明显的“恶心因素”结构，与行为意图存在显着的负相关。对于过去没有食物垃圾分类经验的人来说，这些担忧尤其强烈。这些发现提出了一些潜在的干预措施，包括关于如何分类食物垃圾的教育和扩大路边收集系统，以解决消费者不愿处理废物或清洁收集容器的问题。
Food waste is a growing global issue with widespread environmental, economic, and social impacts. Households are both a major driver of waste generation and a key enabler of solutions such as source reduction and composting. In the U.S., household food waste is still predominantly landfilled, motivating this study to understand the beliefs, experiences, and barriers that individuals face when deciding whether to source separate household food waste as a precursor to landfill diversion. To understand these factors, the theory of planned behavior was applied using data collected via a survey of New York State residents and analyzed using structural equation modeling. Results indicate that attitude, subjective norm, and perceived behavioral control are all significantly and positively associated with the intent to separate household food waste. However, respondents also expressed significant concern that food waste separation would lead to odor, pests, and messiness in the home, ultimately resulting in a distinct “yuck factor” construct that had a significant negative association with behavioral intent. These concerns were particularly strong for individuals who had no past experience separating food waste. These findings suggest several potential interventions, including education on how to separate food waste and expansion of curbside collection systems to address consumers' unwillingness to handle waste or clean collection containers.
