Zero carbon manufacturing through process flow modelling

The pressure on natural resources and emerging environmental legislation are leading manufacturers to adopt solutions to reduce their environmental impact, thereby becoming more sustainable, while enhancing competitiveness. Current approaches in this area are fragmented and clustered around technologies rather than around processes that link the technologies together. There is a need to better understand material, energy and waste (MEW) flows, as well as the interaction between processes in a manufacturing facility from a systemic viewpoint. This paper presents an approach using process flow modelling in order to help manufacturers to identify potential improvements to progress towards competitive sustainable manufacturing. Ultimately they could reach zero carbon manufacturing (ZCM) by having zero material resource degradation, zero net energy demand and zero waste across the system.
