Optimization of granular waste production based on mechanical properties

Abstract Pellet production of food and agricultural wastes is a suitable method to supply livestock feed. Mechanical properties of pellets play an important role in their handling and transportation. In this study, the mechanical properties of pellets made from waste are investigated. After the pelleting process, the pellets were dried with a laboratory convective hot air dryer until reaching a safe moisture content. The effects of feedstock moisture content (0.54, 0.88, and 1.2 kg w  kg DM −1 ), particle size (PS
