Carbonatederived

Carbonatederived is a neologism used to describe materials, chemicals, or processes that originate from carbonation-based reactions or from carbonated feedstocks. There is no canonical definition, and usage varies across disciplines. In one broad sense, carbonatederived materials are those whose formation or procurement relies on carbon dioxide being fixed or incorporated into a product, rather than derived from traditional fossil feedstocks.

Possible interpretations include: (a) polymers and resins produced by CO2 fixation, for example polycarbonates formed via cycloaddition of CO2 with epoxides; (b) inorganic materials formed through mineral carbonation, such as carbonates built from CO2 and metal ions; (c) products manufactured using CO2-expanded or carbonated processing methods that introduce gas phase or carbonate species to modify properties. The term is often discussed in the context of carbon capture and utilization (CCU) and green chemistry, where researchers seek to label and categorize products synthesized from CO2 or carbonate sources.

Research considerations include catalyst development for efficient CO2 activation, life-cycle assessment, energy balance, and end-of-life recyclability of carbonatederived materials. Critics note that the term can be ambiguous without a precise definition, potentially obscuring material identity or environmental benefit.
