Technoeconomic Analysis of Integrated Bioethanol from Elephant Grass (Pennisetum purpureum) with Utilization of Its Residue and Lignin

Bioethanol has been developed as an alternative biofuel. Elephant grass is one of the lignocelluloses that can be used a source bioethanol. The bioethanol fermentation process should improved along with its economic competitiveness to promote wider application. This study aims investigate and evaluate best scheme biethanol (standalone) combination by-products through technoeconomic analysis. method collecting data from several previous studies simulating it SuperPro Designer. Data flowsheeting simulation using Microsoft Excel. results this indicate processing biogas lignin waste fuel lignosulfonates increase value production process. for Biomass Power Plant which called Pembangkit Listrik Tenaga Biomassa (PLTBm) Net Present Value (NPV) IDR 364,358,976,036, Internal Rate Return (IRR) 11.32%, Pay Back Period (PBP) 7.2 years, Profitability Index (PI) 1.08
