BRAIN-TRAINS is a project supported by the Belgian Federal Government that deals with the possible development of rail freight intermodality in Belgium, approaching this transport issue from an interdisciplinary perspective. Life Cycle Assessment (LCA) methodology is used to analyse the sustainability impact of rail freight intermodality. The rail freight system has been divided in three sub-systems: rail transport operation, rail infrastructure and rail transport equipment (locomotives and wagons). First, a SWOT analysis of the intermodal rail freight transport has been performed to identify internal characteristics and possible external trends of the intermodal rail freight transport. The most important elements identified in the SWOT analysis have been selected through a Delphi-technique with the collaboration of a panel of expert. Thirdly, the selected elements have been translated into clear and measurable parameters, defining for every parameter an input value to quantify the scenarios. The parameters are measured in “tonne-kilometre”. Finally, three divergent Belgian scenarios with a time horizon set in 2030 have been built for further analysis. These scenarios are directly linked to the third strategic goal of the European Commission’s White Paper on transport (2011), which aims to shift the 30% of road freight over 300 km to other modes such as rail transport by 2030. As a result, a best, worst and medium case scenarios have been developed, depending on whether the 30% shift has been successfully accomplished, the status quo has been maintained or the goal has not been completely reached by 2030, respectively. The direct transport emissions and energy consumption during the rail transport activity have been determined using the LCA methodology. These LCA results have been used to improve the accuracy of existing commercial databases as Ecoinvent for the Belgian situation. [less ▲]

The aim of this study is to have a good understanding of the environmental impact of glucose production. Glucose is generally produced from corn or wheat. Since agricultural processes are known to be difficult to evaluate by LCA, the results obtained with two different LCA databases, Gabi and EcoInvent, are compared in this work. The production of glucose from raw materials can be divided in two steps: the agricultural step allowing the plant production, and the conversion step including the extraction of the starch from the plant and its hydrolysis into glucose. Preliminary results underline the high impact of the agricultural step, so a special attention has been paid to these data. Specific Belgian data collected by the Walloon Agricultural Research Centre (CRA-W) (2014) [1] have been used as primary data (yield, amount of fertilizers, etc.), either using EcoInvent or Gabi datasets background data to model fertilizers, diesel consumption, etc. A third model was built using only data available in Ecoinvent for corn and wheat cultures. For the conversion step, literature data have been used along with some industrial data. As few studies are available in the literature concerning starch hydrolysis, the focus has been placed on data validation (mass balance checks, cross-reference information, etc.). Based on these multiple sources, it is possible to compare the LCA results for the production of 1 kg of glucose for three different cases, summarized in the following table. Table 1: Summary of modelled cases Agricultural step Conversion steps Primary data Dataset Primary data Dataset Case 1 Belgian GaBi Literature + Industry GaBi Case 2 Belgian Ecoinvent Literature + Industry Ecoinvent Case 2 Ecoinvent Literature + Industry Ecoinvent The results obtained using these three models will be presented, at both the inventory and impact assessment steps. They show significant differences and highlight the need to understand in depth the involved assumptions when developing the datasets, in addition to the ones adopted for the inventory. [less ▲]

When assessing the environmental footprint of a product or an industrial process, ma-jor impacts in climate change and resources depletion are usually linked to direct or indi-rect energy consumptions. Focusing on electricity generation, largely dispersed results can appear for the concerned impact categories depending on the energy mix taken into account. An accurate knowledge of the mix is of major importance for the prediction of the environmental footprint of electricity. As this mix changes from one country to another and through time, regular update is needed to obtain an accurate value of impact for the studied product. Another criteria to also take into account is the specific technology used to generate electricity depending on the primary energy (gas, coal, uranium, sun, wind, etc.). This study aims to generate a simplified tool, containing sufficient data to assess, within a range of 10 % uncertainty, the value of the environmental footprint of electricity, based on a limited amount of accessible parameters. The global life cycle of electricity generation is taken into account, from the resources extraction to the end-of-life. This is essential to be able to compare, on a same basis, the renewable and classical resources for electricity generation. The functional unit of this study for numerical applications is 1 MWhe. To achieve our goal, the following methodological approach has been pursued. First, the energy mix for electricity generation has been collected trough years for different countries. Then a deeper study of specific technologies relative to each kind of primary energy consumption has been performed. Meta-analyses relative to LCA results have been studied to highlight the main important criteria of these technologies. Then, the amount of needed data for the environmental assessment of these technologies has been reduced to the main important ones. The step further is about the use of these data to obtain an available tool to predict the environmental footprint of electricity depending mainly on the energy mix and used technologies. The environmental impact of 1 MWhe can then be easily calculated using this tool in several categories as climate change, acidification, ozone layer depletion, etc. using the ILCD method. Concerning the resources depletion assessment, all available methodolo-gies have been studied with a specific focus on the CEENE method using an exergetic assessment of resources. This method allows the highlighting of the use of energy and all types of resources (fossil, renewable like wind, sun or land). This perspective can also be used to discriminate several resources for the electricity production. A comparison of the results obtained using resources impact methods has then been performed and some challenges concerning the use of existing impact pathways have been highlighted as well as some perspectives to tackle them. This research has been supported by the Public Service of Wallonia – Department of Energy and Sustainable Building within the framework of the ECEB project [less ▲]

Polymers are one of the most used materials and the majority of their production is based on fossil fuels. Due to the decrease of oil resources and concerns about climate change, alternatives are needed, the transformation of biobased ethanol into biobased polymer being one of them. This paper undertakes an environmental evaluation of the production of biobased polymer produced from two different feedstock cultivated in Belgium: sugar beet and wheat. Both crops cultivation are studied as well as their transformation into biobased ethanol, first, and then to biobased ethylene, focusing on high-density polyethylene (HDPE) as final product. These scenarios are analyzed and compared with the production of conventional polymer using the life-cycle assessment (LCA) methodology with reference to relevant environmental impact categories. This study shows a reduction of impact of around 60% for both climate change and fossil fuel depletion categories when using biobased HDPE instead of its fossil counterpart. For all other impact categories, fossil HDPE achieves better results than the biobased product. [less ▲]

This paper undertakes an environmental evaluation of hybrid vehicles recycling, using industrial data from Comet Traitement SA in Belgium. Three business lines have been modelled and analysed. The first one is relative to the business as usual with a dismantling to recover batteries and engines followed by shredding and post shredding treatments. The second one considers, in addition, the removal of electronic control units (ECU) before shredding followed by same steps than in the first line and the last one is relative to the additional removal of big plastic parts before shredding and business as usual post shredding treatments. Results show non-significant environmental benefits when ECU or large parts of plastics are recovered before shredding. Improvements in terms of environmental benefits are lower than the uncertainty of the results. Indeed, the performing usual process for end-of-life vehicles (ELV) treatment reaches 97% of the ELV which is valorised in terms of metal and energy recoveries. Post shredding treatment units include metals, plastics and energy recovery of residues. Comet business as usual route for ELV valorisation is in accordance with the requirements of the European directive and recommendations for further improvement with dismantling of other parts (ECU or plastics) before shredding are non-relevant in this case.

This paper undertakes an environmental evaluation of phosphoric acid production, using industrial data from Prayon SA in Belgium. Phosphoric acid is produced using the wet di-hemihydrate process also called Central Prayon process. Both grades of phosphoric acid are evaluated: fertilizer and purified grades. Specificities of this plant are highlighted and improvements of the process in terms of energy and facilities integration through years are quantified as environmental benefits. The implementation on site of two sulphuric acid production facilities and their energetic integration allow a reduction of climate change impact of 80%. Results also show the importance of phosphogypsum valorisation which is sold for the main part in this case study. Concerning the purified grade, this specific process has been compared to the thermal process, using Best Available Techniques (BAT) values for the modelling. It shows a reduced environmental impact for the wet process in the majority of categories studies. [less ▲]

Dans les matériaux de construction, la notion d’environnement et d’empreinte des produits devient de plus en plus importante que ce soit dans un cadre législatif ou comme objet de marketing. Dans ce contexte, des études environnementales ont été réalisées sur divers produits belges en pierre bleue (dalles, bordures, marches) ainsi qu’en grès (pavés). Ces études ont été menées en utilisant la méthodologie de l’Analyse du Cycle de Vie (ACV) et ont permis de mettre en évidence les étapes prépondérantes de leur production dans une optique d’écoconception ainsi que de les comparer à d’autres produits sur le marché tels que leurs concurrents asiatiques. Les frontières du système comprennent les étapes depuis l’extraction des matières premières, en passant par la production des produits finis ainsi que leur transport sur chantier situé en Belgique. Cette présentation reprend le pourquoi et le comment d’une Analyse du Cycle de Vie, les différentes étapes nécessaires à l’application de l’ACV aux produits en pierre belge ainsi que les principaux résultats. Cette présentation permettra la mise en évidence de l’intérêt de l’ACV et des fiches de déclaration environnementale qui y sont associées ainsi que les perspectives qui peuvent en découler dans le domaine des matériaux et plus précisément pour les matières minérales.

A binder is used to hold together the fibers forming the mineral wool products (see figure 1). These fibers can be produced from sand and recycled glass for glass wool products (see figure 2) or from rock (volcanic rock, typically basalt or dolomite) for stone wool products. Traditionally, the binders used in mineral wool products are based on phenol-formaldehyde. Due to sanitary and environmental considerations and increased focus on indoor air quality, the producers developed new alternative binders. Especially, Knauf Insulation, a worldwide building insulation manufacturer, developed a binder based on plant starch and called ECOSE. In addition of not using added phenol-formaldehyde , this new binder is also supposed to reduce the environmental impacts of Knauf Insulation mineral wools. Moreover, due to its properties, others applications are now considered for ECOSE such as composite wood panels [1]. The aim of this study is to determine the environmental impact of ECOSE and to compare it with more traditional binders using Life Cycle Assessment (LCA) methodology. LCA analyzes the environmental aspects and potential impacts associated with all the stages of a product's life. In this type of environmental assessment the energy and material flows for the entire life-cycle are surveyed and analyzed with special attention to possible environmental hazards or human health problems. The ISO 14040 and 14044 norms [2, 3] provide the general guidance for performing an LCA. The LCA methodology is first applied to ECOSE main component: glucose. The presentation will present results for glucose production from cereals starches After that, first ECOSE application, glass mineral wool products will be presented in details, including production process (see figure 3). The modelling of the glass mineral wool production process in LCA software GaBi 6 [4] is then described. One of the model specificity is that it allows to perform LCA of any glass wool products produced in Knauf Insulation plants in Europe. The adaptations to the model to allow studying former glass wool product when using phenol-formaldehyde binders will also be presented such as the advantages of this model. Moreover, preliminary results about ECOSE and phenol-formaldehyde glass wool products are explained. Références [1] Knauf Insulation. [cited 2014; Available from: http://www.knaufinsulation.ua/en.

The European Commission’s White Paper on transport (European Commission, 2011) seeks to achieve an efficient and sustainable balance between the various transport modes. Environmental impact studies on intermodality transport show that rail freight transport is the land-based transport that has a higher environmental performance compared to intermodal road-rail and all-road transport (Fries and Hellweg, 2014), especially when electrified railway is used (Spielmann and Scholz, 2005). Life Cycle Assessment (LCA) methodology allows us to model as best as possible the environmental impacts of several pollutants in numerous categories. For other categories such as accident damages, noise impact and land use, new developments have to be performed. For the environmental impact assessment, all life cycle phases of rail freight transport operation, rail infrastructure, and rail equipment are taken into account (Spielmann et al., 2007). [less ▲]

This paper undertakes an environmental evaluation of bioethanol production, using wheat cultivated in Belgium. Cultivation steps are modelled using Belgian specific data. Wheat transformation in ethanol relies on industrial data. GHG emissions of the whole life cycle are calculated and compared with the default values given by the European Renewable Energy Directive. Belgian wheat bioethanol achieves a 5% higher GHG reduction than the one mentioned in the European directive but impact repartition is different with a higher importance of cultivation step in our case. Belgian wheat bioethanol complies with the current sustainability criteria but is also able to conform to further ones. Sensitivity analyses are performed on the importance of N fertilizers and associated emissions known as main important parameters. These analyses reveal non negligible variations and then a range of available GHG reduction when using wheat bioethanol. [less ▲]
