The price of recyclable waste has declined, and China is refusing solid waste imports. As a result, recycling companies in South Korea are refusing to collect recyclable waste, which caused a solid waste management crisis in April 2018. Due to this crisis, many people are unable to discard their recyclable waste. This study aims to assess the economic value of a sustainable recycling and waste management policy to solve the waste management crisis. The analysis in this study is divided into two parts: The first part estimates the inconvenience costs to residents using a contingent valuation method, whereas the second part analyzes the preferences for a new policy using a mixed logit model with a choice experiment. The results show that mean willingness to pay (WTP) per household is 41,234 (USD 36.96) KRW/year; the total WTP would be able to increase the total disposal capacity by up to 4.51%. In addition, at an adequate price level for the policy alternative, the policy acceptance rate suggests that the price of biodegradable volume-rate disposal bags should increase by no more than KRW 66 (USD 0.06) per bag. This study provides guidance to policy makers who wish to consider both validity and acceptability.
可回收废物的价格下降了，中国也拒绝进口固体废物。因此，韩国的回收公司拒绝收集可回收废物，这导致 2018 年 4 月出现了固体废物管理危机。由于这场危机，许多人无法处理他们的可回收废物。本研究旨在评估可持续回收和废物管理政策的经济价值，以解决废物管理危机。本研究的分析分为两部分：第一部分使用意愿调查法估计对居民造成的不便成本；第二部分使用带有选择实验的混合 logit 模型分析对新政策的偏好。结果表明，每户家庭的平均支付意愿 (WTP) 为 41234 韩元（36.96 美元）/年；总 WTP 最多可将总处理能力提高 4.51%。此外，在政策替代方案的合理价格水平下，政策接受率表明可生物降解体积率处理袋的价格每袋应增加不超过 66 韩元（0.06 美元）。本研究为希望同时考虑有效性和可接受性的政策制定者提供了指导。
