Total Environmental Impact (TEI) Index

A tool developed and used by INVISTA Antron. Much broader than the traditional industrial measures of raw material consumption and emissions, the Total Environmental Impact (TEI) Index includes value recovery of waste materials, and has a measure of societal impact: e.g., injuries and illnesses to employees and contractors; incidents like fires, explosions, accidental releases to the environment, and transportation incidents; global waste and emissions; and use of depletable raw materials and energy. The TEI Index was created using internal INVISTA studies in North America rationalized with published studies done by Boustead in Brussels and Potting & Blok in the Netherlands.
