Energy Resource Use:Sustainability Metric of a Manufacturing Process
The relationship between energy intensity of a manufacturing process and the production rate has been established as a metric space of the use of energy resources in the context of sustainability.Data related to global,regional,state,sector,industry and process energy resource uses,demonstrate that a significant reduction of energy resources use for a given production rate in manufacturing processes requires an introduction of transformational technologies at the process level,not just a gradual improvement of traditional technologies.In this study we promote another metric,the metric useful for evaluating a need for a transformational technology introduction vs.traditional technologies in terms of a margin between the actual specific energy use and the theoretical minimum,irrespective of technology.An in depth analysis of a brazing process is offered as an example of determining the margin between the theoretical minimum and the actual energy resources use by a state-of-the-art manufacturing process.It has been demonstrated that the energy use,associated with a manufactured product for a particular material processing(including or excluding the investment of the energy resources along the life cycle),is a number of orders of magnitude smaller than the actual energy resources use for the actual process under consideration.
