Abstract:
One of the environmentally friendly solutions for the management of handling organic waste is composting. Bulky nature of loose compost is a challenge in agriculture. However, it can be overcome by pelletizing compost. The most appropriate conditions in die and extruder pelletizer, automated moisture controlling, and mixture systems were studied to produce pellets with desirable qualities. With compost particles of suitable mesh sizes, varying moisture contents, types of binding agents such as rock phosphate, bulk density, pellet length, and disintegration capability were studied. Compost that had been pelletized had a greater percentage of long pellets with high compressive strength and density, with raw particle sizes of about 5 mm and a moisture level of 35%. The density of pellets with binder agent is 1496.1320 𝑘𝑔𝑚โ3 and density of the pellets without binder argent is 1208.1875 𝑘𝑔𝑚โ3.The effectiveness of the machinery and the output increased as compost particle size increased and it was reduced as compost moisture increased. However, the machine's efficiency was decreased for compost that had more binding agents. This study demonstrates that compost pelletization, both with and without binding agents, improved the qualities of compost needed for use in agriculture as well as for transportation and storage. The study mainly focused on the small and medium-scale compost production sector.
