LCA is a relatively new methodology to evaluate the environmental impact of products and processes. This methodology is principally based on the approach “from cradle to grave” because the flow of resources involved in the process or product analysed is followed during their entire life cycle.

In this work LCA methodology is applied to deposition processes for nanostructured coating. The work was performed in the frame of NAPOLYDE project and the main objective was to analyse the efficiency of the new technologies developed in the project from an environmental point of view. Two main technologies was analysed in this work, the first one is based on plasma and the second one is based on sol-gel approach.

In order to evaluate the efficiency of the new technology developed in the frame of NAPOLYDE, a comparative study was performed. In the first part of the typical plasma and sol-gel processes were analysed, in the second part of the work have been analysed deposition process to obtain similar functionality of the coating but using the technologies developed in NAPOLYDE. Finally the results in terms of environmental impact have been compared in order to analyse the environmental efficiency of these new technologies.
