  1. Environmental and socio-economic impacts of landfills

    Danthurebandara, Maheshi; Van Passel, Steven; Nelen, Dirk; Tielemans,Yves; Van Acker, Karel
    A modern landfill is an engineered method for depositing waste in specially constructed and protected cells on the land surface or in excavations into the land surface. Despite the fact that an increasing amount of waste is reused, recycled or energetically valorized, landfills still play an important role in waste management strategies. The degradation of wastes in the landfill results in the production of leachate and gases. These emissions are potentials threats to human health and to the quality of the environment. Landfill gas consists mainly of methane and carbon dioxide, both important greenhouse gases. Landfill sites contribute 20% of...

  2. A techno-economic evaluation of a biomass energy conversion park

    Van Dael, Miet; Van Passel, Steven; Pelkmans, Luc; Guisson, Ruben; Reumerman, Patrick; Marquez-Luzardo, Nathalie; Witters, Nele; Broeze, Jan
    Biomass as a renewable energy source has many advantages and is therefore recognized as one of the main renewable energy sources to be deployed in order to attain the target of 20% renewable energy use of final energy consumption by 2020 in Europe. In this paper the concept of a biomass Energy Conversion Park (ECP) is introduced. A biomass ECP can be defined as a synergetic,multi-dimensional biomass conversion site with a highly integrated set of conversion technologies in which a multitude of regionally available biomass (residue) sources are converted into energy and materials. A techno-economic assessment is performed on a...

  5. Phytoremediation uncertainty tackled : a real option approach

    Compernolle, Tine; Van Passel, Steven; Huisman, Kuno; Kort, Peter

  6. Organische zonnecellen als rechtstreekse energiebron voor consumentenelektronica

    Lizin, Sebastien; Van Passel, Steven; De Schepper, Ellen; Vranken, Liesbet
    Organische zonnecellen kunnen op lange termijn een significant marktaandeel veroveren in de niche van de door fotovoltaïsche zonne-energie aangedreven consumentenelektronica. Dit op voorwaarde dat actie ondernomen wordt in het verhogen van de efficiëntie en levensduur van deze zonnecellen. Deze productkenmerken bepalen immers het meest de voorkeur van de (Vlaamse) consument.

  7. The value of dynamic remediation processes: a real option approach

    Compernolle, T.; Van Passel, S.; Lebbe, L.; Huisman, K.; Kort, P.; Thewys, T.
    Restricted by limited resources, the management of problems related to soil and groundwater contamination involves the search for a balance between costs and bene fits, integrating the knowledge from multiple disciplines. A wide range of economic decision tools are available to support the remediation selection process, including Cost Bene fit Analysis (CBA), risk-based CBA, and multi-criteria analysis. However, these tools do not take into account the reversibility of a remediation strategy. Aim of this study is to examine the value of a bioremediation project embedding the option to redirect the remediation process once it is proved that the investment would not...

  8. The impact of soil contamination on agricultural land prices in the Campine region

    Schreurs, Eloi; Hoogmartens, Rob; Thewys, Theo

  9. Assessing the natural and economic value-creation of innovative biobased processes

    Maes, Dries; Van Passel, Steven
    Industry is confronted with systemic environmental problems such as limited fossil resources, sustainability concerns of renewable resources, toxicity of end products and waste accumulation. This triggers the pursuit of new processes and business models. New pathways are being developed together with authorities and academia. For instance, the agro-industrial and chemical sector define pathways including biorefineries, material production from organic waste and sustainable chemistry. Will this help the transition towards a sustainable economy? Several authors indicate various principles as a prerequisite for such a sustainable economy: (i) virgin fossil resources should be banned from use, (ii) the utilisation of man-made toxic...

  10. How much CO2 do the European Cattle farms waste? A reallocative group efficiency perspective

    Ang, Frederic; Van Passel, Steven

  11. A Ricardian analysis of the impact of Climate Change on European Agriculture

    Van Passel, S.; Massetti, E.; Mendelsohn, R.
    This research estimates the impact of climate on European agriculture using a continental scale Ricardian analysis. Date on climate, soil, geography and regional socio-economic characteristics were matched for 37 612 individual farms across the EU-15. Farmland values across Europe are sensitive to climate. Even with the adaptation captured by the Ricardian technique, farms in Southern Europe are predicted to suffer sizeable losses (8%-13% per degree Celsius) from warming. In contrast, agriculture in the rest of Europe is likely to see only mixed impacts. Increases (decreases) in rain will increase (decrease) average farm values by 3% per centiliter of precipitation. Aggregate...

  12. Higher sustainability performance of intensive grazing versus zero-grazing dairy systems

    Meul, Marijke; VAN PASSEL, Steven; Fremaut, Dirk; Haesaert, Geert
    Although grazing of dairy cows is an integral part of dairy farming in many European countries, farmers today more often choose for zero-grazing systems, where cows are housed throughout the year. Some studies already compared grazing and zero-grazing systems for specific issues such as labor efficiency, environmental impact, or animal welfare. In our study, we perform a more integrated evaluation, considering relevant ecological, economic, and social aspects. This allows for a balanced and more complete comparison of the sustainability performance of the two production methods. We evaluated ten intensive grazing and ten zero-grazing specialized Flemish dairy farms on the use...

  13. Food Miles to assess sustainability: A revision

    Van Passel, Steven
    Sustainability assessment is an essential process in our aim to reach a more sustainable production and consumption pattern. This research revises the food mile concept as a guiding tool to assess sustainability. Food miles measure the distance that food travels from where it is grown or raised to where it is consumed. Three different concepts to assess sustainability are described:(i)food miles,(ii)enhanced food miles, (iii)food chain sustainability. An illustrative case study shows that there is a strong danger of oversimplification when using food miles as an assessment tool. Second, the food miles concept can be enhanced with all relevant transport externalities...

  14. From evaluating sustainability performance to supporting agricultural management: case of intensive grazing versus zero-grazing dairy systems

    Meul, Marijke; Marchand, F.; Van Passel, Steven; Fremaut, D.; Haesaert, G.
    We performed an integrated evaluation of the sustainability performance of 10 intensive grazing and 10 zero-grazing specialised Flemish dairy farms, using a selection of sustainability indicators from MOTIFS(Monitoring Tool for Integrated Farm Sustainability). We put special effort in formulating useful management advice for farmers of both groups. Therefore, we used multiple regression to identify the most influential factors(independent variables) for each inicator value(dependent variable)and, through correlation analysis, related the selected factors to specific farm management indicators such as farm intensity or concentrate use; they were used to formulate general management advice. More detailed site- and case specifi advice was delivered...

  15. Groundwater remediation and the cost effectiveness of phytoremediation

    Compernolle, T.; Van Passel, S.; Weyens, N.; Vangronsveld, J.; Lebbe, L.; Thewys, T.
    In 1999, phytoremediation was applied at the site of a Belgian car factory to contain two BTEX plumes. This case study evaluates the cost effectiveness of phytoremediation compared to other remediation options, applying a tailored approach for economic evaluation. Generally, when phytoremediation is addressed as being cost effective, the cost effectiveness is only determined on an average basis. This study however, demonstrates that an incremental analysis may provide a more nuanced conclusion. When the cost effectiveness is calculated on an average basis, in this particular case, the no containment strategy (natural attenuation) has the lowest cost per unit mass removed...

  16. Determining potential locations for biomass valorization using a macro screening approach

    Van Dael, Miet; Van Passel, Steven; Pelkmans, Luc; Guisson, Ruben; Swinnen, Gilbert; Schreurs, Eloi
    European policy states that by 2020 at least 20% of final energy consumption should come from renewable energy sources. Biomass as a renewable energy source cannot be disregarded in order to attain this target. In this study a macro screening approach is developed to determine potential locations for biomass valorization in a specified region. The approach consists of five steps: (1) criteria determination, (2)data gathering, (3)weight assignment, (4) final score, (5)spatial representation. The resulting outcome provides a first well balanced scan of the possibilities for energy production using regional biomass. This way policy makers and investors can be supported and...

  17. Risk balancing at the household level: Implications for policy and risk management

    de Mey, Yann; Wauters, Erwin; van Winsen, Frankwin; Van Passel, Steven; Vancauteren, Mark; Lauwers, Ludwig
    Traditionally, agricultural economists employ farm level modeling for a variety of purposes. Central to these modeling techniques is the behavioral assumption of farm profit maximization, or, when risk preferences are put into play (risk aversion), utility maximization. However, there is abundant literature, from different (sub)disciplines such as farming systems research, rural sociology, rural development and rural economic geography that views farm household activities in the wider economic context (e.g. Gasson et al., 1988, Dries et al., 2011, Bessant, 2006). In such view, farm households are considered pluriactive and may distribute assets between agricultural and non-agricultural purposes to accomplish their goals....
