Many case studies (material and energy balances, material and process information systems) have been carried out in the last 30 years with the result of a LCA-engineering database with ca. 1500 industrial processes and technology information database for ca. 5000 enterprises. In these case studies different methods have been applied (macromodels, input-output analysis, value analysis, LCA, linear programming).
Members of ITAC are active participants in national and international standardisation work for LCA/LCC methodology in connection with SETAC, ISO, CEN.
