In Taiwan, municipal solid waste (MSW) is separated into general, recyclable, and food waste categories. General waste must be packaged into pre-paid trash bags before final disposal. Recyclable items and food waste are collected separately to reduce the costs of using pre-paid trash bags. This study applied a choice experiment approach to evaluate marginal willingness-to-pay (WTP) in different MSW disposal system scenarios. Variables include cleanliness, location for purchasing pre-paid trash bags, frequency of waste collection, and distance to waste disposal. The results indicate that cleanliness, location, and distance influence public behavior, acceptance, and participation. Higher collection frequency decreases public acceptance. Some of the socio-economic variables of the respondents, including age, education, and marriage status, affect MSW management alternatives. The marginal WTP of the scenarios in this study ranged from US$0.04-0.07 per trash bag. Online purchasing of pre-paid trash bags is more cost-effective and should be encouraged. The results of this study provide useful information for the development of policies related to waste management systems.
在中国台湾，城市固体废物（MSW）分为一般、可回收和厨余垃圾三类。一般废物在最终处理前必须包装在预先付费的垃圾袋中。为了降低使用预先付费垃圾袋的成本，可回收物和厨余垃圾被分开收集。本研究采用选择实验方法来评估不同 MSW 处理系统情景下的边际意愿支付（WTP）。变量包括清洁度、购买预付垃圾袋的地点、垃圾收集频率以及到垃圾处理场的距离。结果表明，清洁度、地点和距离影响公众的行为、接受度和参与度。较高的收集频率会降低公众的接受度。受访者的一些社会经济变量，包括年龄、教育程度和婚姻状况，会影响废物管理的替代方案。本研究情景的边际 WTP 范围为每个垃圾袋 0.04-0.07 美元。鼓励在线购买预付垃圾袋，因为这样更具成本效益。本研究的结果为制定与废物管理系统相关的政策提供了有用的信息。
