What are EPD’s and why are they important?

An EPD (Environmental Product Declaration) is an environmental transparency report that testifies objective, comparable and third-party verified data about products and services’ environmental performances from a lifecycle perspective. Whereas the EPD score is the final declaration of a product, the foundation of any EPD score is the life cycle assessment (LCA). This LCA allows you to evaluate your product’s environmental performance over its entire life cycle. It typically takes into consideration your full value chain, from material extraction to manufactured product, its usage stage and end of life. 

Metakaolin – The super pozzolan

We’ve talked about Purebase’s pozzolanic metakaolin, our supplementary cementitious material (SCM) that can replace Portland cement up to 20%, and our high-performance SCM, which can replace up to 40% cement in a concrete mix design. These materials ultimately can reduce a vast portion of greenhouse gases caused by the production of cement. But what exactly is a pozzolan; what is the difference between raw pozzolans and calcined pozzolans, and what classification does our metakaolin land in?

What are pozzolans?

A pozzolan is a siliceous or siliceous and aluminous material that, in itself, possesses little or no cementitious value but will, in finely divided form and in the presence of moisture, chemically react with calcium hydroxide at ordinary temperatures to form compounds having cementitious properties. It is therefore classified as supplementary cementitious material (SCM). There are both natural (ACI 232.1R) and artificial (fly ash, ACI 232.2R, and silica fume, ACI 234R) pozzolans.1


Purebase Corporation (OTCQB: PUBC) is a California-based company that is dedicated to providing solutions to some of the world’s most pressing climate challenges we face today.
