Agricultural crops became through years a possibility to increase European energy independence. Brazil has taken this opportunity since the seventies by using sugar cane bioethanol as vehicle fuel. The development of biofuels production is more recent in Europe. Due to temperate climates, bioethanol production is mostly based on wheat and sugar beet, this latter being considered as the ‘equivalent’ sugar crop to sugar cane for Europe. Biofuel is the most common application of bioethanol but its transformation into bioethylene through a dehydration step can be an alternative as already found in Brazil. This paper will consider both potential uses and compare them using Life Cycle Assessment methodology. Common boundaries of the systems comprise the cultivation step for both crops, i.e. sugar cane and sugar beet, with all associated energetic and fertilizer consumptions, the transportation step from field to the industrial plant, the sugar crops transformation into hydrate bioethanol and the by-products valorisation. For the biofuel scenario, a dehydration step using molecular sieve is added to get anhydrous bioethanol. For the bioethylene scenario, an industrial dehydration step is added. Direct comparison between both scenarios is not possible due to different products uses. The comparison was then performed for both scenarios between the bio-based product and its fossil equivalent. ReCiPe 2008 method was used to get the environmental impacts. As expected, the impact of bio-based products in climate change and fossil fuel depletion categories decreases compared to the fossil counterparts. For other categories, difference is less significant and results are often better for fossil products. Land use change category was implemented to assess its importance. Depending on assumptions, the greenhouse gas emissions from crop implementation on a natural land can counteract the previous mentioned benefits. This study shows the importance of assumptions, especially in the agricultural field, on the obtained results. [less ▲]

Waste is considered as a major concern of our century. New technologies and attempts to improve appeared through years. The goal of this study was to evaluate the improvement of waste management through the last forty years. Four steps of time and of technologies of waste treatment were evaluated in an environmental point of view using the life cycle assessment methodology. The first scenario is situated before 1970 with waste landfilling in an open dump without recuperation and valorization of gas. The second one considers the situation between 1990 and 2008 with a plant comprising grinding and sorting of waste to obtain refused derived fuel fraction (RDF) which was burnt in an incinerator, remaining waste being sent to sanitary landfill with recuperation and valorization of gas in electricity. The third one is the current one, in operation since 2009, with incineration of the whole of the residual municipal waste. The last scenario is about future considering the current installation and adding a biomethanation plant using the collected biodegradable fraction of household waste. This environmental evaluation was performed in accordance with the ISO standards 14040 and 14044 and the environmental impacts were calculated with the ReCiPe methodology. We modeled a specific plant situated in Liege using its technical and environmental reports to be as realistic as possible. Main result of this study is the improvement through years starting from the important environmental impact for the landfilling of waste in an open dump to an environmental gain for some categories with the current installation coupled with biomethanation. Global warming impact from the eighties was reduced by 9 in the years 1990-2008 and by 14 for the current scenario alone or coupled with a biomethanation plant. Some sensitivity analyses were used to evaluate the strength of assumptions with for example using a consequential LCA instead of an attributional one and modifying the electricity origin mix. An uncertainty analysis using Monte-Carlo method showed the robustness of our results. This study confirms the environmental improvement of technologies and emissions of waste management through years. [less ▲]

Afin d’évaluer le caractère environnemental d’un matériau, des outils d’évaluation existent. Le plus complet est l’Analyse du Cycle de Vie qui est une méthodologie normée internationalement (ISO 14040-14044) permettant d’obtenir l’impact environnemental d’un produit tout au long de son cycle de vie. Les résultats d’une telle étude peuvent être déclinés pour obtenir une fiche de déclaration environnementale des produits étudiés, permettant d’illustrer l’impact des différentes étapes sur l’environnement. Ces fiches ont également pour but la comparaison environnementale de produits ayant la même application. Notre étude est basée sur l’évaluation environnementale de produits en pierre naturelle, à savoir la pierre bleue et le grès à travers divers produits finis. Le but premier de cette étude est de mettre en évidence les étapes responsables du plus grand impact environnemental pour chaque produit et ainsi permettre à la carrière étudiée de revoir ses positions et de modifier certaines lignes de conduite afin d’améliorer les impacts environnementaux obtenus. Au vu de la compétition asiatique régnant sur le marché des pierres naturelles, un volet supplémentaire de l’étude a été consacré à l’évaluation de l’impact environnemental des concurrents directs des produits mentionnés ci-dessus. Pour conclure, l’Analyse du Cycle de Vie va devenir, au fil des années, une démarche incontournable à étendre à chaque carrière, et à la production de matériaux de construction au sens large, afin de leur donner les ressources nécessaires pour relever le défi du développement durable.

This study performs the environmental product declarations for three Belgian mineral products, two granite and one sandstone paving. Both main goals of this work were to obtain Belgian environmental product declarations to strengthen existing databases and to get similar information for their Asian counterparts. Indeed, competition with China for bluestone products and with India for sandstone pavement is very important due to very competitive prices despite their foreign origin and possibly higher induced environmental impacts. Environmental product declarations of Belgian bluestone and sandstone products were conducted in accordance with the ISO standards and following the stand-ard NF P 01-010. CML 2001 method was used to obtain environmental impacts for ten categories as climate change, acidification, abiotic resources depletion, etc. Boundaries of the Belgian systems are the same and the life cycle assessment comprises all steps from the extraction of minerals to the implementation on site. Use and end of life steps were neglected due to the low required maintenance and the inert nature of the paving. For Asian products, the analysis is reduced to the transportation of the functional unit, mainly due to the lack of reliable data. This work highlights the negative effect of long distance transportation of heavy and non-energetic products. Indeed, the environmental impacts of the sole transport of Asian products are at least as important as those obtained for the whole life cycle of Belgian products, whatever the category taken into account (climate change, acidification, air pollution, etc.). CML 2001 methodology was successfully applied to these five studies about three Belgian products and two abroad transportation steps. Comparison of the 5 corresponding environmental product declarations permits to highlight the importance of the transport on environment and to promote, supposing equal performance, local prod-ucts in a more environmental-friendly point of view.
