Abstract : The purpose of this PhD thesis is to establish an eco-design method based on Life Cycle Assessment, that should allow identifying action levers specific for each economic actor of the life cycle of a product, for improved environmental performances. Life Cycle Assessment was coupled with two methods of sensitivity analysis in five steps: (i) definition of objectives and system, (ii) modeling calculation of inventory and impact indicators with different approaches according to foreground and background sub-systems, (iii) characterization of parameters using a typology specific to possibilities of control of the considered economic actor, (iv) application of two sensitivity analysis methods (Morris and Sobol) and (v) results interpretation in order to identify potential efficient improvements. The approach was applied on the hemp concrete insulation product, including agricultural production, industrial transformation of hemp fibers, and use of hemp concrete as a thermal insulator for buildings. The approach provides potential technological scenarios improving environmental performances for each single economic actor of the product’s life cycle. Performing the method presently requires additional information, but will probably be paid back in the future by driving more robust choices for a given product.
