| dc.description.abstract | The plant design for the manufacture of bioplastic from empty fruit bunches by
acetylation process has a production capacity of 50,000 tonnes/year and operates
for 330 days a year. The main processes in this preliminary plant design consist of
three stages, namely the pulp formation stage, the cellulose acetate production stage,
and the bioplastic production stage. The pulp formation stage uses a digester that
operates at a temperature of 80°C and a pressure of 1 atm for 60 minutes. The
cellulose acetate formation stage uses an acetylation reactor that operates at a
temperature of 53°C and a pressure of 1 atm for 60 minutes, requiring 228.795
kg/hour of cellulose with a reaction conversion of 98%. Then, in the bioplastic
manufacturing stage, a mixing tank operating at a temperature of 30°C for 30
minutes is used, requiring 340.499 kg/hour of cellulose acetate, 5,809.629 kg/hour
of dichloromethane solvent, and 116.192 kg/hour of polycaprolactone. Bioplastic is
molded using a single screw extruder. The plant location is planned in Sei Mangkei
Special Economic Zone, Simalungun, North Sumatra with an area of 19.376,4 m2.
The planned form of business entity is a Limited Liability Company (PT) with a
total workforce of 169 people. For the establishment and operation of the plant
requires investment capital of IDR 1.825.058.521.720,80 and production costs of
IDR 1.473.135.443.504,54. Based on the feasibility analysis, this plant has a BEP
of 32.76%, ROI of 27.81%, POT for 3,6 years, RON of 45.35%, and IRR of 24.94%.
From the results of economic analysis, it can be concluded that the pre- design of
bioplastic production plant from empty fruit bunches by acetylation process is
feasible. | en_US |
