Abstract
Mechanochemical treatments are the oldest humankind’s processes. By grinding with a mortar and a pestle, the first extractions of natural pigments from biomasses were performed in prehistorical time. Today, after thousands of years, mechanochemical processes are exploited again as frontiers in extraction and synthesis due to their advantages in terms of economic and environmental sustainability. The use of reactive extrusion in extraction and biomass conversion is just at the beginning, and more studies are needed to discover its true potential.
