Abstract


The increasing demand, capacity constraints and resource restrictions, has led to a rapid increase in the cost of water and energy in South Africa. The South African manufacturing industry remains the third largest consumer of water and second largest consumer of national energy consumption. The improvement of water and energy efficiency is becoming an increasingly important theme for both organisational success and national economic sustainability. This paper presents the Lean based Water and Energy Stream Mapping framework developed for the manufacturing industry, with the specific objective of decreasing its water and energy intensity. As with the traditional Value Stream Mapping tool, the Water and Energy Stream Mapping focusses on the elimination of water and energy specific wastes within a process. Water and energy waste categories which will be utilised in conjunction with the framework will also be discussed. The key objective of this paper is to detail the process of creating the Water and Energy Stream Map, as well as the statistical forecasting methodology used to develop the baseline waster and energy demand data. The outcome of the implementation of the framework is the future state Water and Energy Stream Mapping, which effectively is a blueprint for increased water and energy effciiency within in a studied process.
