The Effect of Adding Vinasse for Biochar Production from Bagasse by Pyrolysis Method

The increasing industrial waste was caused problems for the environment. Bagasse is a solid produced from sugar industry. Vinasse bioethanol industry liquid molasses which contains much nutrients. vinasse and bagasse in this study developed into biochar. This aimed to determine effect of addition on biochar characteristics. yield characteristics were then compared. Based gravimetric, pH, SEM-EDX analysis, result indicated that adding yield, water content ash content, lowering tend increase nutrient levels (carbon, nitrogen, potassium). by pyrolysis had 6.682-9.406%; 7.0-8.2%; 4.8-13.6%; at pH 8.4-88; carbon (C) 65.07-80.88%; nitrogen (N) 2.06-8.66%; potassium (K) 0.00-2.15%, while phosphorus (P) not detected analysis. consideration highest elements needed plants, optimum obtained with 7.5%.
