“…El objetivo primario fue la excavación de los residuos para la recuperación de un área donde se encontraba construido el relleno sanitario (Malik & Bharti, 2009;Frändegård et al, 2013;Quaghebeur et al, 2013;Masi et al, 2014); Actualmente, aún se carece de información sistemática sobre proyectos o experiencias en el tema; a continuación se comentan algunos de los más conocidos.…”

“…Además de lo expuesto, los beneficios de la producción de biogás, más allá de reducción de emisión de gas con efecto invernadero, incluyen el potencial para la mejora de la calidad de aire local a través de la destrucción de hidrocarburos aromáticos polinucleares (HAPS) y compuestos orgánicos voláti-les (VOCs) por medio de la combustión (Zapata et al, 2013;Masi et al, 2014).…”

“…However, little information is known about the mechanism of bonding these metals to the soil and also the mechanism of releasing these metals from the soil [1]. Metal concentration and bioavailability vary according to the time and environment and depends on the variation of the soil properties like the composition, the reduction/oxidation reaction, adsorption/desorption and on the chemical properties of the received metals [2].…”

“…These heavy metals have an excellent potential to transfer to the ecological system and the food chain [1,2]. Different methods have been used for the remediation of metals from soils like extraction with chelating agents (EDTA or other biodegradable agents) [3], sequential acid leaching [4], washing [5], hydrometallurgy technique [6], Bioelectrochemistry [7] and phytoremediation [8].…”

The potentional of plants to cleanup metals from an old landfill site

Old landfill sites contain different hazardous materials like heavy metals which have the ability to affects the entire environment. These places are sometimes covered by plants to increase the stability of the soil and to reduce the effects of erosion. 15 soil samples (3 samples from each place) and 5-7 timothy-grass (Phleum pretense) plants from 5 different places were taken from an old landfill place in an active landfill site in Högbytorp /Sweden owned by Ragn-sells Group Company. XRF scanning was used to analyze the metal content of soil samples and of plants. High concentrations of metals were detected in the soil samples like Fe with an average of about 25000 ppm, Mn about 250 ppm and 2800 ppm of Ti. The plants results showed an average concentration of Fe in the shoots about 730 ppm, Mn about 60 ppm and Ti about 1760 ppm. On the other hand, the roots results showed an average concentration of about 10 000 ppm of Fe, about 160 ppm of Mn and 2200 ppm of Ti. These results gave the indication that the Timothygrass has the ability to extract metals from contaminated soils and can help to cleanup these soils.

“…Given the multiple nature of landfill mining in which several objects can be met, landfill mining has been interpreted as a recycling operation (Paper IV;EPA, 2015;Jones et al, 2013;Masi et al, 2014), a remediation activity (cf. Paper II; EPA, 2013; Kurian et al, 2003;Hogland et al, 2004;Frändegård et al, 2013) or a mining activity (cf.…”

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...
