ENERGY EFFICIENCY ASSESSMENT IN PRODUCTION LINE: A SUSTAINABLE MANUFACTURING APPROACH

Abstract

An increasing demands of the energy which causes a quick depletion of the natural energy reserves within the earth has become a critical concern by the human society. Additionally, anthropogenic activities which generate carbon emissions is indicated as the primary cause of many environmental adverse impacts and the climate change. Industrial sector is concerned to be the largest energy consumer compared to other sectors. Manufacturing enterprises majorly expend energy intensively within the production lines. Thus, an energy efficiency improvement tends to be a proper solution to addressing this problem. This work aims to analyze a prospect energy efficiency improvement within a production line. A discrete-event simulation (DES) was used to investigate the energy saving potential and a case study was conducted in a crumb rubber company. Three parameters were taken into consideration to calculate the energy consumption, i.e. processing time, material flow, and machine states. An initial model which represents an actual condition of the manufacturing production line was developed. From the analysis of the initial model result, a recommendation scenario was built. It was shown that a reduction of 8.22% in the energy consumption is achievable by implementing the suggested scenario.
