Monetizing the social benefits of landfill mining: Evidence from a Contingent Valuation survey in a rural area in Greece

摘要

Despite the emerging global attention towards promoting waste management policies that reduce environmental impacts and conserve natural resources, landfilling still remains the dominant waste management practice in many parts of the world. Owing to this situation, environmental burdens are bequeathed to and large amounts of potentially valuable materials are lost for future generations. As a means to undo these adverse effects a process known as landfill mining (LFM) could be implemented provided that economic feasibility is ensured. So far, only a few studies have focused on the economic feasibility of LFM from a private point of view and even less studies have attempted to economically justify the need for LMF projects from a social point of view. This paper, aiming to add to the limited literature in the field, presents the results of a survey conducted in a rural district in Greece, by means of the Contingent Valuation method (CVM) in order to estimate society's willingness to pay for LFM programs. According to the empirical survey, more than 95% of the respondents recognize the need for LFM programs. Nevertheless, only one-fourth of the respondents are willing to pay through increased taxes for LFM, owing mainly to economic depression and unemployment. Those who accept the increased tax are willing to pay about €50 per household per year, on average, which results in a mean willingness to pay (WTP) for the entire population under investigation of around €12 per household per year. The findings of this research work provide useful insights about the 'dollar-based' benefits of LFM in the context of social cost-benefit analysis of LFM projects. Yet, it is evident that further research is necessary.
