Pellets are small, rounded or cylindrical pieces of material, often made from compressed substances like wood, plastic, or metal. They are commonly used in various applications, including fuel for heating, animal feed, and as a raw material in manufacturing. Wood pellets, for example, are popular as a renewable energy source for stoves and boilers. In addition to their use in energy and feed, pellets can also serve in the pharmaceutical industry, where they are used to create controlled-release medications. The uniform size and shape of pellets allow for consistent dosing and improved efficiency in production processes.
