Greener Alternatives Three Categories


A new icon has been added to identify our Greener alternative products. Products with this icon fulfill one of the three criteria.

  • Products reengineered by Sigma-Aldrich scientists significantly improving their environmental footprint
  • Products that align with the 12 Principles of Green Chemistry
  • Products that help make greener alternatives possible “Enabling Technologies”


Re-engineered Products
Products that are in the re-engineered category are those products that are manufactured by Sigma-Aldrich. Members of the Worldwide Green Chemistry Committee have developed new ways to manufacture the products that use fewer resources, are less hazardous and/or generate less waste. We’ve also introduced an industry first scoring system to quantify the improvement in environmental footprint.  Learn more by visiting the Matrix Scoring explanation page.


12 Principles Aligned Products
These products demonstrate one or more characteristics that align with the 12 Principles of Green Chemistry. Examples of these products include a new line of products from one of our supply chain partners – Biomatrica®. The ambient storage technology of this company enables sample storage without the need for ultra-low-temperature freezers aligning with Green Chemistry Principle # 6 “Design for Energy Efficiency.”


Enabling Products
Enabling products are those that enable the research of alternative energy. Products from the Sigma® Life Science and Aldrich® Materials Science portfolios are being used by scientists in novel ways to help find new solutions to unlock the power of nature through biofuels or other nanotechnologies. Our Materials Science Portfolio includes a wide variety of novel and tested materials used for energy generation, storage, and efficiency. This portfolio includes a wide variety of small-molecule chemicals, polymers, nanomaterials, as well as metals and ceramics. Sigma-Aldrich maintains a number of collaborations with leading universities to develop and test the latest in alternative energy materials, and is a leader in making these materials available to the research community as well as in assisting with the commercialization of new technologies.
