Abstract: The biomass is a promising way to substitute fossil fuels. Lignocellulosic biomass valorisation is part of second generation technologies. They are interesting in that they imply less competition with food crops for land and water, and they allow for the whole plant to be processed. Moreover, lignocellulose is abundant in cheap and non-food materials extracted from plants such as wood and energy crops. The thermo-chemical route is being considered more extensively, especially the gasification process. This process converts carbonaceous biomass into combustible gases (CO, H2, CO2, CH4, and impurities) called syngas in the presence of a suitable oxidant. The syngas can be converted into a large range of products, such as diesel, via a Fischer-Tropsch process, or methanol, used for producing DME (dimethyl ether), both of which can serve as fuels in traditional motors. Syngas can also be used to produce ethylene and propylene, two building blocks for the chemical industry. Production of these four compounds is specifically investigated. In order to insure that, under the principle of sustainability, the use of lignocellulosic biomass is a viable alternative, its environmental impact must be accurately quantified. The Life Cycle Assessment (LCA) methodology will be used in this regard for the gasification process. The gasification technology will be described, and a state of the art in LCA of the gasification process will be presented. Finally, the need for new research will be established. [less ▲]

MODELING OF A GLASS WOOL PROCESS IN VIEW OF LIFE CYCLE ASSESSMENT (L.C.A.)

Taking into account the environmental aspects in the building sector has become unavoidable. In France, environmental and sanitary statements for building products (“Fiches de Déclarations Environnementales et Sanitaires” (FDE&S)) have been developed. The environmental part of the statement is based on Life Cycle Assessment. So, KnaufInsulation, glass wool producer for the French market, has started to evaluated the environmental impacts of it process in view of FDE&S realization. The process has been modeling in GaBi with industrial data. Adjustable parameters have been introduced to allow to study the environmental impacts of almost all the KnaufInsulation products. So the FDE&S can be easily done for the different products. This model is also used for eco-conception. The LCA results allow to show the life cycle leaks. More, in modifying the model, the impact of a change in the process on its environmental performances will be highlighted. So relevant improvement will be brought out. The model and the mains results as the eco-conception strategy will be presented. The interest of making a modeling based on the step and process of the life cycle of a product or a product range will be clearly understood. [less ▲]

The thermo-chemical route, especially the gasification process is considered. This process converts carbonaceous biomass into combustible gas (CO, H2, CO2, CH4 and impurities) called syngas and this syngas can be converted into a large range of products. Production of four of these compounds is specifically investigated: ethylene, propylene, diesel and DME. Diesel can be produced via a Fischer-Tropsch process, whereas DME (dimethyl ether) can be obtained directly or from methanol which is obtained from syngas. DME and diesel can serve as fuels in traditional motors. Syngas can also be used to produce ethylene and propylene, two building blocks for the chemical industry. An important bibliography study has been done to understand these processes in order to evaluate their environmental impacts. The Life Cycle Assessment (LCA) methodology will be used in this regard. A bibliography study on the LCA articles published in this filled has been performed and it appears that few studies have yet focused on the environmental impacts of the gasification process and production of biofuels. Most of the time, they do not use the LCA methodology or they do not take into account land use change impact and are only “well-to-tank” studies. Moreover, it seems that the production of building blocks for the chemical industry has never been investigated. During the next stages of this work, the best conversion routes of lignocellulosic biomass, in an environmental sense, will be determined. Gasification will also be compared with the fossil sector and the results will be checked by sensitivity and uncertainty analyses. The economic aspect will also be taken into account, for the better process, in an environmental view. So, the results of the full study will be a decision making tool for the industries involved in biomass valorisation and for governments. [less ▲]
