LIFE CYCLE ASSESSMENT OF NUTMEG OIL SUPPLY CHAIN

Abstract

The nutmeg oil supply chain has several members, including farmers, collectors, traders, processing industries, and exporters. Every activity along the nutmeg supply chain has an environmental impact due to resources usages such as raw materials, water, and energy.  This study aimed to measure the environmental impacts along the nutmeg oil supply chain using a life cycle assessment framework. The effects assessed in this study are greenhouse gas emissions, global warming potential (GWP), and acidification potential (AP). The research stages involve preliminary study, objectives and scope determination, data collection, environmental impacts measurement, and interpretation. The results showed that the most significant environmental impact was the distillation process with greenhouse gas emissions are 22,400 kg CO2, 60kg CH4, and 0.8 kg N2O, GWP of 23,908 kg CO2 (eq), and AP of 34 kg SO2 (eq). Based on identifying of environmental impacts, it is necessary to improve the existing boiler combustion system by using a closed burning system. These study results are the basis for decision-makers to improve the production process, design green supply chain management, and reduce environmental impacts.
