What does pelletisation mean?
Pelletisation is the industrial or mechanical process of converting a loose or powdered substance into small, compact pellets. The resulting pellets are generally uniform in size and easier to measure, transport, store, and feed into machinery than the original bulk material. The term is especially common in discussions of animal feed, fertilizer, biomass fuel, plastics, and chemical manufacturing, although the same general principle can apply to many materials. “Pelletisation” is the standard British spelling, while American English generally uses “pelletization.” The related verb is “pelletise” in British usage and “pelletize” in American usage. As a specialist term, pelletisation is not commonly used in general conversation, but it precisely identifies a widely employed method of changing a material’s physical form without necessarily changing its chemical composition.

Pelletisation turns loose powders and bulk materials into compact, uniform pieces that are easier to store, transport, and use.

Where does pelletisation come from?
Pelletisation is formed from the English word “pellet” together with the suffix “-isation,” which indicates the process of making or converting something. “Pellet” comes through Old French from Latin pila, meaning “ball” or “round object.” The Latin root also underlies related words such as “pilule,” while the spelling with -ization reflects the American preference for -ize forms.
