Food waste remains a high priority greenhouse gas (GHG) emission problem and household curbside collection – green bin¹ - with mass treatment is often adopted as a viable solution for GHG reduction. The aim of this study is to explore attitudinal and situational predictors of support for residential curbside green bin programs. Using responses to 517 household surveys from the mid-sized Canadian cities of London, Ontario (proposed green bin program) and Kitchener-Waterloo (KW), Ontario (operating green bin program for 10+ years) comparison of means t-tests, correlations and linear regression are used to test five hypotheses derived from the food waste and waste diversion literatures that predict green bin support: situational factors, current food wasting, theory of planned behaviour attitudes, concern that green bin encourages food wasting, and concern that food waste ends up in the garbage regardless of green bin. There is some support for all five hypotheses. Residents in Kitchener-Waterloo were significantly more supportive (83%) than those in London (65%). While residents in both communities are supportive because of the perceived convenience and environmental benefits of the green bin, the number of regression model predictors is greater in London (16 compared to 9 for Kitchener-Waterloo). The findings overall suggest sustained municipal education at the implementation stage may lead to positive resident habituation to green bin and thus, durable public buy-in.

食物垃圾仍然是一个高度优先的温室气体 (GHG) 排放问题和家庭路边收集——绿色垃圾箱¹- 大规模处理通常被用作减少温室气体的可行解决方案。本研究的目的是探索支持住宅路边绿色垃圾箱计划的态度和情境预测因素。使用来自安大略省伦敦（提议的绿色垃圾箱计划）和安大略省基奇纳-滑铁卢（KW）（运营绿色垃圾箱计划 10 多年）等加拿大中等城市的 517 个家庭调查的答复，比较均值 t 检验、相关性和线性回归用于测试从食物浪费和废物转移文献中得出的预测绿色垃圾箱支持的五个假设：情境因素、当前食物浪费、计划行为态度理论、绿色垃圾箱鼓励浪费食物的关注以及食物浪费的关注无论绿色垃圾箱如何，最终都会进入垃圾桶。所有五个假设都有一定的支持。基奇纳-滑铁卢的居民 (83%) 的支持率明显高于伦敦 (65%)。虽然两个社区的居民都支持绿色垃圾箱的便利性和环境效益，但伦敦的回归模型预测变量的数量更多（16 个，而基奇纳-滑铁卢的 9 个）。调查结果总体表明，在实施阶段持续的市政教育可能会导致居民对绿色垃圾箱的积极习惯，从而获得持久的公众认同。
