The PSI Sustainability Model is a program that was developed to demonstrate the wide range of economic, social, and environmental benefits that can be realized by Wisconsin’s small and midsized manufacturers through the implementation of sustainable business practices. PSI utilizes a triple bottom line approach (sometimes referred to as “people, planet, and profits”) and a cost-benefit analysis to assess current sustainability efforts and identify opportunities for improvement. It is a comprehensive, proven program that cuts costs while enhancing the resource efficiency of the supply chain.
Projects range from replacing low-efficiency light fixtures, to reducing the use
of toxic substances and the resulting wastes, to reducing raw material use and scrap
production, to replacing old machinery with energy-efficient models, to optimizing
freight routes and shipping schedules.
