The production of Melaleuca leucadendron essential oil generates a lot of solid waste, since only under 2% take it out as the oil product. The solid waste contains cellulose as an important content which can be isolated by alkaline treatment of sodium hydroxide (NaOH). In this project, optimization of alkaline treatment of M. leucadendron twigs (MLT) waste was studied in order to obtain optimum isolated cellulose. The experiments were conducted at atmospheric pressure and boiling temperature. The 33 Box-Behnken design (BBD) was used to evaluate the effects of treatment time, solid loading and NaOH concentration. Quadratic model evaluation showed that the model is a prospective to describe the effects of the variables (R2=0.8994, p<0.05). The significant variables were found in linear term of NaOH concentration and quadratic term of treatment time. The optimum result of the experimental variables range was predicted in treatment time, solid loading and NaOH concentrations of 60 minutes, 10%, and 1.83% respectively. In conclusion, BBD is appropriate to optimize cellulose isolation process of MLT.
