Production and Physical Properties of Pellet Mixed with Cattle Manure Compost and Biochar

Short Introductive summary

Production characteristics and physical properties of pellets mixed with cattle manure compost and biochar were revealed by flat die pellet mill, which is used for fertilizer production and wood pellets. Agricultural application of biochar has attracted attention in recent years in terms of carbon sequestration in the soil, but dust is generated during fertilizer application of powdered charcoal and plowing. Pelleting solves the above risks and improves handling during spreading, transportation, and storage, but it is difficult to pelleting biochar without a binder. Livestock manure compost can be easily pelleted on its own and used as a binder for biochar. From the compost side, the mixing of biochar leads to an easy reduction of moisture content (20-30% W.B.) to the optimum level for pelleting without requiring any energy input. Two types of powdered biochar were used as samples: rice husk charcoal and char generated as a residue from wood gasification power generation. In both biochar, energy consumption per unit pellet production did not decrease at the 25% mixing ratio compared to compost alone. The mechanical durability of the pellets, which affects powdering during spreading
