What does pelletization mean?
Pelletization is the process of converting a loose or finely divided material into small, compact pellets. The resulting pellets are generally easier to handle, measure, store, transport, and use than the original powder or granules, which can flow freely, form dust, or separate into components. The term occurs especially in plastics manufacturing, where molten or powdered plastic is formed into reusable pellets, and in biomass and animal-feed production, where compressed plant material becomes a convenient fuel or feed product. Pharmaceutical pelletization can also control the size, density, and release characteristics of a drug formulation. Although pelletization and palletization sound similar, pelletization creates compact pellets, while palletization means placing goods on pallets for handling or transport.
nounThe process of forming a finely divided material into small, compact pellets. It is especially used in manufacturing plastics, biomass fuels, animal feed, and pharmaceutical products.
- The process or technique of forming material into small, compact pellets.
- The result of forming material into pellets, especially as a characteristic of a manufactured product.
"Improved pelletization increased the material's density and made it easier to store and transport."
"The pellets maintained their shape throughout the pelletization process."
"Fuel pelletization improves the handling and storage of powdered biomass."
The plural is uncommon because pelletization is usually discussed as a process rather than as a countable event.
"The engineers compared different pelletizations of the same powdered material."
Pelletization turns loose powder into palm-sized fuel: the same basic idea can help a factory ship granules or heat a home.

Where does pelletization come from?
The word is formed from "pellet" plus the suffix "-ization," a combining form associated with the process of making or converting something. "Pellet" comes through Middle French from a term meaning a small ball or ball of food and is ultimately connected with Latin "pila," meaning a ball or pillar. In pelletization, the original sense of forming a small compact ball underlies the modern industrial process.
