The aim of this study was to produce Aminotosan$^{(R)}$ fertilizer using optimized chitosan coagulant from waste livestock blood. Amino-acid fertilizer was produced by pretreated livestock blood. Chitosan coagulant was aggregated with amino-acid fertilizer to produce Aminotosan$^{(R)}$. Optimized coagulation conditions were set using chitosan coagulant such as 10% citric acid and 500 ppm chitosan coagulant by analysis of CST and TTF. The efficiency of coagulation by chitosan coagulant under the optimal conditions was better than chemical coagulants. After solid/liquid separation for coagulated amino-acid fertilizer, Aminotosan$^{(R)}$ fertilizer which added eco-friendly and aesthetic functions was produced.
