In today’s fiercely competitive environment, the goal of any enterprise is to make money now and in the future (Goldratt, 1992). In order to fulfill this goal, an enterprise should eliminate waste embedded in the value stream. Industrial engineers frequently play a key role in reducing cost. The philosophy of many in lean manufacturing is that the things that can’t be measured can’t be properly managed (Womack & Jones, 1996). This thesis presents a method to incorporate an environmental index into the value stream and thereby increase the opportunities for waste minimization. The proposed method of incorporation of the environmental index is explained in detail using a hypothetical case study. How to calculate the environmental index, the present state and future state maps of the value stream are explained in detail. The two major steps presented by this method are: Identify environmental wastes and incorporate the identified wastes into the value stream map. For determining the method among given alternatives, this thesis uses the Waste Stream Prioritization Method WSPM) (TNRCC, 1998). It also provides an activity based model (IDEF0) to present the method for incorporating the environmental index
