Description:
The Industrial Process System Assessment (IPSA) methodology is a multiple step allocation approach for connecting information from the production line level up to the facility level and vice versa using a multiscale model of process systems. The allocation procedure assigns inputs (e.g., raw materials) and outputs (e.g., emissions) to a particular product and its associated manufacturing process. This is an essential starting point when evaluating product sustainability for complex facilities in the course of preparing inventory data for a product’s life cycle assessment. All detailed equations and assumptions used in the development of IPSA are described in this paper. This work was conducted as part of a Cooperative Research and Development Agreement between The Procter & Gamble Company and the United States Environmental Protection Agency to develop novel tools for the evaluation of sustainable supply chains of consumer products. This research presents the IPSA methodology as a fundamental tool and new standard for evaluating and designing more sustainable products and industrial processes.
