Welcome to the
Green Chemistry Index v2.0
Foreword by Dr. John Warner, Director, Warner-Babcock Institute of Green
"Sustainability efforts in institutions across the world have become mainstream
and ubiquitous. Although much attention and resources are being spent on such activities,
there does not exist a universal understanding of how sustainability can be truly
measured and tracked to determine the actual success of any "sustainability endeavor".
The iSUSTAIN™ Index provides the user with a CREDIBLE and QUANTIFIABLE assessment
of the relative sustainability of a material process. This tool is useful to retrospectively
analyze an existing process or help design a new process with a focus on sustainability.
The iSUSTAIN™ Index provides the user with a respected way to articulate the
environmental performance aspects of a process up and down the customer supply chain.
From a technical perspective it can be an invaluable design tool. From a marketing
perspective it can help communicate the true value of a process to internal and
external clients. From any perspective the iSUSTAIN™ Green Chemistry Index
provides an objective assessment to effectively plan efforts across an organization
while not inhibiting the existing structure."
The iSUSTAIN™ Green Chemistry Index is a tool which provides a methodology to generate a sustainability-based
score for chemical products and processes. It contains a set of sustainability
metrics based on the Twelve Principles of Green Chemistry* and takes into
account such factors as waste generation, energy usage, health and environmental
impact of raw materials and products, safety of processing steps, and others.
To use the iSUSTAIN™ Index, the user generates a scenario. The scenario contains information
on the materials going into a process (the Bill of Materials In or BOM In), the
materials out of a process (the product and any waste streams - the Bill of Materials
Out or BOM Out) and the conditions used for the various steps in a process (the
Process Steps). Several alternative scenarios can be generated for the same product/process,
making changes within them to evaluate their effect on the overall sustainability
score, thus allowing the user to do a "what-if" analysis.
The internet-based version of the iSUSTAIN™ Green Chemistry Index was developed with two goals in mind:
- Afford a measure of the sustainability for products/processes to both
develop an initial sustainability baseline and provide guidance for process improvement
- Act as a learning tool for the scientific community to provide increased
familiarity with the Twelve Principles of Green chemistry and help scientists gain
an appreciation of the factors within their control that can affect the overall
sustainability of their processes
The iSUSTAIN™ Green Chemistry Index has been developed through an alliance
between Cytec Industries Inc., a sustainability-minded specialty chemicals
and materials company; Sopheon, a leading provider of software and services
for product lifecycle management; and Beyond Benign, a non-profit organization
dedicated to green chemistry education and training.
