The aim of the project is to adapt and to validate the use of a technology developed by Thales to realize for lightning generation to the fragmentation of panels (solar , isolation and radiological). This technology was proved to be efficient on the fragmentation of several kind of materials but no test has been performed on screens/panels, because these requires a full-time team, specialized in the chemistry in aqueous environment wich was not available in Thales at the time of the studies. Within the framework of this program, Thales will use its two prototypes : - One realized, fully sponsored by Thales, operating on the principle of indirect electric arc through water - One realized, during an Eco-industrie 2010 projet, dedicated to the destruction of the small WEE, using the principle of direct arc through water. During this study the scientific teams of Thales, the ENSAM/MAPIE and ENSCP Paristech will try to go deeper into the knowledge of the physical phenomena at stake. These research on the electric, mechanical and chemical effects have for objectives: ·The understanding of the physical phenomena which leads to the fragmentation. The aim is the realization of a better adapted reactor: oModification of electrodes and the shape of wave (study of the electric phenomena) oModification of the shape and the material of the reactor (study of the mechanical phenomena) oChoice of the liquid (chemical study and knowledge of the electric properties of materials) ·The definition of the chain of recycling of the secondary primary materials. oDefinition of the filtering and the research for recycling and for remediation of the solid extracts oDefinition of the methods of recycling the liquid extracts and the separation of the vaporisable materials. This study will allow to assess the gain brought by this technology compared to the means of more classic recycling of panels. There could be several kind of gains: -Economic: oBy recycling and reselling the materials of products at the end of life oBy decreasing the not valued rubbishes -Ecological: oBy decreasing the quantity of buried waste oBy using a concept of "clean" treatment -Design: oAuthorization to use composite panels in an approach of eco design. oSupply new rules of eco-design linked to the new processing procedure and assess the economic and ergonomic gain. Products used for the study are: -Radiologic panels produced by Trixell -lead protected hoods in carbon fiber produced by Trixell -Solar energy panels supplied by the INES -Hight performances Thermic isolation panels supplied by INES The feasibility of the recycling of raw materials will be validated by ENSAM and ENSCP ParisTech. The economic gains will be calculated by each of the suppliers of panels. The ecological gains will be validated by ENSAM and ESCP ParisTech by taking into account treatments being realized on damaged screens and based on studies of global life cycle of produced (gain in the production by recycling rubbishes) The gains in design will be presented by the industrialists on the advices of ENSAM. Then, the industrial specifications of a machine adapted to the problem of panels will be presented by Thales.
