DOZN 2.0—A Quantitative Green Chemistry Evaluator for Sustainable Future

Ettigounder (Samy) Ponnusamy, MilliporeSigma

MilliporeSigma (the life science business of Merck) developed and launched DOZN 2.0, a unique web-based greener alternative scoring matrix, also known as a quantitative green chemistry evaluator, based on the 12 principles of green chemistry for customers to evaluate their relative greenness of their processes. 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. DOZN 2.0 calculates scores based on manufacturing inputs, GHS and SDS data which provide a green score for each substance. DOZN 2.0 is flexible enough to encompass the diverse portfolio of products ranging from chemistry to biology to material science based products. The DOZN 2.0 system has also been verified and validated by a third party to ensure best practices are applied. DOZN 2.0 offers customers an increased breadth of greener alternative products with confirmatory scores to validate greener characteristics. Through DOZN 2.0, customers now have access to calculate the green scores of their processes and products. This free, web-based tool provides users with more data so that they are properly equipped to improve their sustainability. DOZN 2.0 keeps data privacy top of mind allowing customers to score their processes/products in a safe and secure manner.
