Intelligent Sustainability STEM Framework Part 2
These equations within the ISSTEM framework continue to illustrate the adaptability and relevance of mathematical modeling in addressing sustainability challenges across various industries and domains. 51. Sustainable Packaging Impact Index (SPII): Purpose: Assessing the environmental impact of packaging materials and designs. Application: Packaging industry, product design, and waste reduction. Example Equation: � � � � � = 1 � ∑ � = 1 � ( � � � � � � ) × � � � SP I I i = n 1 ∑ j = 1 n ( E ij R ij ) × C ij where � � � R ij is the recyclability, � � � E ij is the energy efficiency, and � � � C ij is the cost for packaging solution � i . 52. Sustainable Water Treatment Efficiency (SWTE): Purpose: Optimizing water treatment processes for efficiency and sustainability. Application: Water utilities, wastewater treatment, and environmental engineering. Example Equation: � � � � � = 1 � ∑ � = 1 � ( � � � � � � ) × � � � S W T E i = n 1 ∑ j = 1 n ( E ...
