Environmental footprints are usually calculated for the products of the manufacturing industry, like phones, cars, lamps, etc. Lot of work has also done to evaluate LCA values of different energy sources. However, much less attention is given to the role of process industry, which produces raw materials for the manufacturing industry. The environmental footprints of the metals and chemicals are highly dependent on the process technology and the metallurgical infrastructure, which is used in the primary and secondary production of materials.
This training module review the role and impact of the process industry on the primary LCA data used in the manufacturing industry. Also, analysis of systems is done on the basis exergy.
It shows the very complex nature of multi-material and metal processing in the circular economy value chain. To analyse these systems requires sophisticated tools as shown below, that create a digital platform that combines different tools to analyse the depth of the system.
The key objective of this module is simulation-based footrprinting of systems and will be covered by:
● a discussion and presentation providing an overview of system simulation for the circular economy;
● an overview of some of the tools and platforms;
● a class-based exercise to develop viewpoints and lessons learned for learners: aluminium recycling is provided as a cases study to understand the effects of impurities, dilution etc. on the recycling rate, exergy dissipation and energy losses during processing;
● an example, which will be used to calculate exergy and energy losses as well as recycling rates; and
● key guiding topics for teachers in the class-based exercise are given in the notes in the presentation.
