Abstract
Life Cycle Assessment is nowadays a powerful method to compare the full range of environmental damages as- signable to products, services or processes, in order to be able to assess them and to choose the least burden- some one. To perform the LCA, all the fluxes entering and exiting the chosen system must be assessed, which involves most of the time a difficult collection of data, called Inventory, which hardly verify mass and energy balances. From the precision of those data depends the accuracy of the LCA. If the system studied does not ex- ist yet, as it is precisely the case for the ULCOS breakthrough processes, establishment of the inventory be- comes uncertain. To overcome this difficulty a novel method has been developed, in the framework of ULCOS SP9 WP2, which consists in replacing the traditional inventory data collection by a rigorous process modelling step which pro- vides all the data required for the Inventory. Such a methodological coupling of process modelling and LCA permits rigorous assessment of existing processes and future ULCOS processes as well.
