The life cycle of a product is generally characterized by the main following stages: raw materials acquisition, manufacturing, processing and formulation, distribution and transportation, use, re-use, maintenance, recycle and waste management. As regards the process, the following stages are usually distinguished: raw materials acquisition, process manufacture, use and dismantling at the end of the lifetime. Considering the life cycle concept in a risk analysis approach requires the adjustment of the classic risk analysis methodology. In order to build up this new methodology called LCRA (Life Cycle Risk Assessment), we relied on the LCA (Life Cycle Assessment) methodology, which allows the assessment of the potential environmental impacts throughout the life cycle of a system. Once these adjustments made, this new methodology LCRA is explained and applied to two energy pathways (or life cycles): hydrogen (produced from the biomass) and gasoline pathways. |
