Two important concepts in industrial engineering discipline are standard and sustainability. In any production system, standards to sustain the quality of products and the surrounding environment must be taken into consideration. To learn how the two concepts are executed in practice, an implementation of ISO 14001 in a milk industry is studied. Prior this study, the milk industry has already been certified by ISO 14001: 2004 to regulate the daily production and to maintain its environmental concern. In 2015, International Organization for Standardization (ISO) introduced a new standard for environmental management system by publishing ISO 14001: 2015, which revised the older ISO 14001: 2004. Consequently, to sustain the milk company’s compliance with regard to the milk product and beverage processing standards, it must prepare itself to adapt to the new ISO 14001: 2015 standard. This research aims to design an environmental management system which refers to ISO 14001: 2015, and to draft the mandatory set of documents and records. The methodology used in this research firstly collects the data by interview and observation. Further, the collected data is analysed and assessed with respect to the compliance of ISO 14001: 2015. The result shows that there are 4 unfulfilled clauses and 1 partially-unfulfilled clause based on the standard. Thus, several transformations and adjustments need to be done within the milk industry if the company wants to acquire ISO 14001: 2015 standard.
