GreenSuite® Alternative Assessments of Chemicals, Products, and Processes (Spring 2013)George Thompson, President & CEO, Chemical Compliance Systems, Inc.Alternative assessments can be based upon the hazard, risk, lifecycle, or sustainability impact of a chemical substance by itself, within its manufacturing process, or from the product containing the chemical. The complexities involved with these alternative assessments cannot be credibly fulfilled by a single system, such as GreenScreen®. In addition, since alternative assessments are intended to “eliminate or reduce potential exposures” to chemicals of concern, banning chemicals is not the only available option, especially when exposures can be reduced or eliminated by other means. GreenSuite® is a set of existing software modules populated with chemical and regulatory data that identify the hazards of chemicals and their risks within a manufacturing process, or a finished product, so exposures can be maintained at safe levels within each stage of the lifecycle, as well as across the entire lifecycle, thus avoiding the need to ban the chemical. GreenSuite® utilizes 44 ecological, health, and safety endpoint criteria from the national “Greener Chemicals and Processes Information Standard” (ANSI 355) to quantitate the hazards and risks on a scale of 0-100%. Comparative analyses for alternative chemicals, manufacturing processes, or product formulations can be completed within 3-5 seconds.
