ENVIRONMENTAL PRODUCT DECLARATION for IMPROVAC®1

With regard to Improvac production (upstream and core processes), the main contributors to theenvironmental impact categories are identifi ed: about Global Warming Potential from fossil resourcesuse, the electricity-related processes are responsible for approximately 57% of the impact; thedominant contribution to the Global Warming Potential from biogenic sources comes from the DEAEDextran production, deriving from a microbial fermentation of ethanol.About the Acidifi cation impact category, the hard coal burning, at power plant, for electricityproduction is the dominant player; fi nally, for the Eutrophication impact category the most relevantcontributor depends on the biomass for ethanol production (DEAE Dextran production).Solid Waste generationData concerning solid waste generation are split into two categories – hazardous and not hazardous– and refer to the whole system (Table 5).Table 5.
