GLRPPR Sector Resource: Benchmark Life-Cycle Inventory and Impact Assessment of Sheet-fed Printing Systems Using Soy-Based Ink
Benchmark Life-Cycle Inventory and Impact Assessment of Sheet-fed Printing Systems Using Soy-Based Ink
Written by Duane A. Tolle, David P. Evers, and Bruce W. Vigon, this report discusses a study which was performed to document the life-cycle environmental impact characteristics associated with the use of soy-based inks by evaluating a typical ("generic") soy-based ink currently used in significant quantities for sheetfed printing. This typical soy-based ink printing system serves as a benchmark for future comparison with alternative ink formulations and other combinations of printing system materials. The life-cycle impact assessment (LCIA) included identification of specific processes in the streamlined life-cycle (core operations associated with material acquisition, manufacture, use, and disposal) of soy-based ink for sheetfed offset lithographic printing that make the greatest contribution to the overall environmental profile for the baseline soy ink printing system selected. The intent was to identify processes that could be modified to make reductions in environmental impact, thereby enhancing soy-based ink printing as an environmentally preferable choice. It should be noted that an LCIA is a hazard indicator system largely based on resource use and emission loading, and should not be construed to represent actual environmental impacts.
