Waste-to-energy (WtE) projects use municipal waste to generate energy. While they increase local environmental and health risks, they also generate local environmental and economic benefits. If facility operator characteristics influence perceptions of risks and benefits, does public support for a WtE facility change if it is operated by a foreign firm? Using a survey experiment in Thailand (n = 829), we examine support for a hypothetical WtE plant operated by local Thai (reference category), Japanese (treatment 1), and Chinese (treatment 2) firms. We find that while respondents are less supportive of WtE plants operated by Chinese companies ("penalty for foreignness"), their support does not change for Japanese plants (neither penalty nor premium for foreignness). Importantly, while perceptions of local economic benefits increase support, perceptions of environmental benefits from reducing waste and landfills do not. Respondents support WtE plants when their communities experience air pollution from coal-fired power plants and when they support the Thai government's decision to ban the manufacturing and sale of single-use plastics.
垃圾转化能源(WtE)项目利用城市垃圾来发电。虽然它们会增加当地的环境和健康风险,但也会产生当地的环境和经济效益。如果设施运营者的特征会影响对风险和效益的认知,那么当一个WtE设施由外国公司运营时,公众对它的支持会改变吗?通过在泰国进行的一项调查实验(n = 829),我们研究了对一家假设的由泰国当地公司(参照类别)、日本公司(处理组1)和中国公司(处理组2)运营的WtE工厂的支持情况。我们发现,虽然受访者对由中国公司运营的WtE工厂的支持度较低(“对外来者的惩罚”),但他们对日本公司运营的工厂的支持度并未改变(既没有对外来者的惩罚也没有优待)。重要的是,虽然对当地经济效益的认知会增加支持度,但对减少垃圾和垃圾填埋场带来的环境效益的认知却不会。当受访者所在社区遭受燃煤发电厂的空气污染时,以及当他们支持泰国政府禁止制造和销售一次性塑料的决定时,他们会支持WtE工厂。
