DOZN Tool for Green Chemistry Working Group

Lead: Samy Ponnusamy, Ph.D., MilliporeSigma

The working group held a free webinar, Panel Discussion: DOZN/Green Chemistry and the Future for Sustainable Labs, during which panelists from a variety of industry backgrounds discussed the growth in green chemistry and the potential value of the DOZN Quantitative Green Chemistry Evaluator. If you missed the webinar, you can watch the recording here or download the PowerPoint Presentation.

The working group also developed a survey to better understand how the community gauges the potential of green chemistry to influence decisions in the lab. If interested in sharing your ideas and feedback, please take a few minutes to complete the online survey.


MilliporeSigma created a unique, web-based greener alternative scoring matrix, also known as DOZN™2.0 - A Quantitative Green Chemistry Evaluator, based on the 12 principles of green chemistry. The 12 principles of green chemistry provide a framework for learning about green chemistry, and designing or improving materials, products, processes, and systems. DOZN™2.0 scores products based on metrics for each principle and aggregates the principle scores to derive a final aggregate score. The system calculates scores based on manufacturing inputs, Globally Harmonized System (GHS), and Safety Data Sheet (SDS) information, which provides a green score for each substance and is flexible enough to encompass a diverse portfolio of products ranging from chemistry to biology-based products. The DOZN™2.0 system has also been verified and validated by a third party to ensure best practices are applied. This new greener chemistry initiative offer customers an increased breadth of greener alternative products with confirmatory documentations to validate greener characteristics. Through MilliporeSigma’s DOZN™2.0 platform, customers can now calculate the green scores for their own processes and products. This free, web-based tool provides users with even more data, so that they have more information to increase sustainability.

More information can be found on the MilliporeSigma website.

The purpose of this I2SL working group is to promote awareness of green chemistry and the DOZN tool of MilliporeSigma and what role they can play in furthering planning, design, construction, and operation of energy efficient and sustainable laboratories.


The I2SL DOZN working group will explore, promote, and apply the DOZN tool when upgrading existing or building new lab facilities or developing new processes. The group is also collaborating with Beyond Benign.

Committee Composition

Lab planners, designers, and engineers are encouraged to participate.

Get Involved

The working group is trying to better understand how the community gauges the potential of green chemistry to influence decisions in the lab. You can share your ideas and feedback by taking a brief survey.
