In addition to the individual tests, some of the conversion factors produced by LCA have been
provided by the literature for some products such as plastic, metal and textile production
industry. These conversion figures should be used with caution taking into consideration the
limitations of the analysis, which is a major element in LCA studies. The following table details
the conversion factors required for the different activities in the study (table 6).
