선택실험법을 이용한 유기성 폐기물 에너지화 시설 확대의 비시장적 편익 추정

Plans for the expansion of organic waste-to-energy (OWtE) facilities are being widely adopted across Korea as part of efforts to mitigate green house gas emissions. OWtE is the process of generating energy in the form of electricity and/or heat from organic waste. This study tries to estimate the non-market benefits of enhancing the ratio of OWtE from 26% to 100% by 2020 using a choice experiment (CE). A CE survey of 1,000 households was undertaken, investigating the trade-offs between price and the three attributes for selecting a preferred alternative to obtain a marginal willingness to pay (MWTP) estimate for each attribute. The study employs a nested logit model and the results reveal that the MWTP for a 1% increase in energy security, the doubling of landfill life expectancy, and the creation of new jobs resulting from expanding OWtE facilities are estimated to be KRW 237, 148, and 15 per household per year, respectively. This information will be useful in the evaluation and planning of OWtE projects.
