Abstract

The industrial sector is today responsible of about 20-50 % (respectively countries with a long/new productive tradition) of final energy consumptions. Big margins of improvement still exist and also other positive effects would arrive about various related issues (environmental, social, economical). Different studies approached the general goal of “Sustainable factories”, each focusing on a particular aspect of the problem (architecture, production, machineries, management, etc.). This work focuses on energy and material flows used in productive areas, giving an appropriate measure and representation of their actual behaviour. The resulting overview provides to the owner a general but deeper knowledge of the system, as basis for detecting critical points and bottlenecks, for future interventions, for company strategy and for continuous monitoring activities. Furthermore this study can allow to focus on some of the previous topics of “Sustainability”, with more consciousness of their mutual influences. For this purpose a method has been proposed, consisting of some elaborations to give an idea of the system as it is and to propose new optimized scenarios. The analysis shows both the quantity and the quality of flows, using energy and exergy concepts. A graphical representation of the results makes the tool simple and the comparison between different systems easier. After having this holistic view, the possibilities of optimization can be investigated, re-introducing some outflows as input in the same system or in some others - about which the same analysis has been developed. An added value is thus obtained from possible networking in comparison to single interventions, as Industrial Ecology stated. All assessments take into accounts the economical aspect. The application of the methodology on two existing case studies highlights interesting results and limits when dealing with real systems.
