“…Public or social benefits are also important in assessing feasibility of landfill mining projects, such as improving the urban landscape and the quality of ground water, building new parks on the old landfill, and increasing employment opportunities. Marella and Raga (2014) pointed out that the externalities should be taken into account for economic evaluation of landfill mining projects, in such a way that projects generating higher social benefits are not overlooked and can be favored through tailored policies and support schemes. Ayalon et al (2006) studied the benefits from the engineering rehabilitation (i.e.…”

“…The external benefits should be quantitatively identified and transferred to visible profits by subsidies, tax remissions or other supportive policies to ensure the cost-benefit feasibility of landfill mining. According to previous researches, choice experiment (CE) was applied for assessing the external costs of landfill siting (Sasao, 2004), and contingent valuation method (CVM) was applied for assessing the external benefit of landfill mining and landfill rehabilitation (Ayalon et al, 2006;Marella and Raga, 2014). The methods of quantitatively assessing the external benefits need further studies to give scientific support for the policy makers, and the results of external benefits of landfill mining may be varied from different cases.…”

“…Followed by this methodology, built a CBA simulation tool considering the costs of landfill mining including excavation, sorting and pre-treatment, incineration and contingency, and the benefits including waste to material (WtM), waste to energy (WtE) and land reclamation. Moreover, contingent valuation method (CVM) was applied for assessing the social benefits of landfill mining and landfill rehabilitation (Ayalon et al, 2006;Marella and Raga, 2014). Previous studies have reported useful methodologies for assessing the economic feasibility of landfill mining, but the CBA model and the site-and facility-specific indicators require further discussion.…”

a b s t r a c tLandfill mining is an environmentally-friendly technology that combines the concepts of material recycling and sustainable waste management, and it has received a great deal of worldwide attention because of its significant environmental and economic potential in material recycling, energy recovery, land reclamation and pollution prevention. This work applied a cost-benefit analysis model for assessing the economic feasibility, which is important for promoting landfill mining. The model includes eight indicators of costs and nine indicators of benefits. Four landfill mining scenarios were designed and analyzed based on field data. The economic feasibility of landfill mining was then evaluated by the indicator of net present value (NPV). According to our case study of a typical old landfill mining project in China (Yingchun landfill), rental of excavation and hauling equipment, waste processing and material transportation were the top three costs of landfill mining, accounting for 88.2% of the total cost, and the average cost per unit of stored waste was 12.7 USD ton À1 . The top three benefits of landfill mining were electricity generation by incineration, land reclamation and recycling soil-like materials. The NPV analysis of the four different scenarios indicated that the Yingchun landfill mining project could obtain a net positive benefit varying from 1.92 million USD to 16.63 million USD. However, the NPV was sensitive to the mode of land reuse, the availability of energy recovery facilities and the possibility of obtaining financial support by avoiding post-closure care.

“…It came into use to estimate the benefits of outdoor recreation in the Maine backwoods of the United States [20]. CVM is widely used in many fields, such as measuring valuation for publicly financed health care services [21], assessing landfill mining projects [22], understanding public perceptions of nuclear power [23], conducting an economic valuation of forest ecosystem services [17], and so on. However, few studies on CVM have focused on Chinese wetlands.…”

Determinants of Farmers’ Willingness to Pay and Its Level for Ecological Compensation of Poyang Lake Wetland, China: A Household-Level Survey

2014

View full text Add to dashboard Cite

This study examines the determinants of farmers' willingness to pay (WTP) and their payment levels for ecological compensation of the Poyang Lake Wetland in China. We developed a farmer household survey and gathered 292 effective responses. The contingent valuation method (CVM) and Heckman's two-step model were employed for the empirical study. Results show that 46.58% of farmers are willing to pay ecological compensation, with an average price of $64.39/household per year. The influencing factors that significantly influence farmers' WTP include household income, residential location, emphasis on improvement of wetland resources, arable land area, and contracted water area. In addition, household income, residential location, arable land area, and contracted water area are significantly related to their payment levels. The results of this empirical study inform important policy implications and recommendations.

“…Systems analysis tools are increasingly used to evaluate the resource, environmental or economic potentials of full-scale landfill mining operations. These studies have shown that landfill mining can potentially lead to environmental and social benefits, but has difficulties in making a positive turnover (Frändegård et al, 2013;Van Passel et al, 2013;Marella & Raga, 2014;Jain et al, 2014;Herman et al, 2014;Damigos et al, 2015;Danthurebandara et al, 2015;Frändegård et al, 2015;Winterstetter et al, 2015).…”

Landfill Mining : Institutional challenges for the implementation of resource extraction from waste deposits

Landfill mining is a term to describe the emerging field of exploring and extracting disposed material. The recovery of deposited resources may increase the flows of secondary resources and thereby replace a significant share of the primary production. The extraction of deposited materials may also be integrated with remediation and after care measures, to handle the many problematic landfills. Such unconventional recycling practices are, however, currently limited. The research in the field has mainly focused on technical evaluations of sorting efficiency, economic feasibility, and resource and environmental potential. Other issues of concern to institutions, markets, policy and conflict of interest have received considerably less attention.This thesis consists of five scientific articles that have been synthesized. The overall aim of the thesis is to examine the institutional conditions for the implementation and emergence of landfill mining. This is addressed by three research questions. The first question concerns how policies come into play in a landfill mining operation and its consequences for the implementation and emergence of landfill mining. The second question is devoted to understanding these policies and why they look the way they do. Based on how policy influences landfill mining operators and how these policies can be understood, the third question seeks to formulate some overall institutional challenges for the emergence of landfill mining, and how the authorities' capacity to address the institutional challenges may increase.The result shows that current policy makes it difficult for landfill mining operators to find a market outlet for the exhumed material, which means that landfill mining may result in a waste disposal problem. Regulations also restrict accessibility to the material in landfills. Therefore, it has generally been municipal landfill owners that perform landfill mining operations, which directs learning processes towards solving landfill problems rather than resource recovery. Landfill mining is not, however, necessarily to be perceived as a recycling activity. It could also be understood as a remediation or mining activity. This would result in more favorable institutional conditions for landfill mining in terms of better access to the market and the material in the landfill.The regulatory framework surrounding landfills is based on a perception of landfills as a source of pollution, a problem that should be avoided, capped and closed. Extracting resources from landfills, challenges this perception and therefore results in a mismatch with the regulatory framework. On the other hand, the material in mines is typically regarded in the formal institutions as a positive occurrence. Mining activities are regarded as the backbone of the Swedish economy and therefore receive various forms of political support. This favorable regulatory framework is not available for secondary resource production. Based on the identified institutional conditions, institutional challenges are id...
