Methodology for appreciation the manufacturing castings from perspective of circular economy

This paper presents a methodology for studying the trends toward developing circular economy, comprising the following steps: description the field analyzed statistically and technological, establishing assessment criteria, establishing the event which will be analyzed and its description and evaluation of the event from the perspective of circular economy. The case study was designed to the manufacture castings through the analysis, after the methodology proposed, by the work of the 71-th World Foundry Congress in 2014 from Bilbao. The conclusion of this approach shows us that the manufacture castings through the trends expressed fall in the principles of circular economy. At the level of resources needed for the manufacturing process of castings - specifically immaterial resources, materials and energy, are analyzed at all levels, specific phases, namely: 1. Information analysis specific for the field; 2. Analysis preparation in terms of manufacturing technology and technological infrastructure available; 3. Analysis of manufacturing castings; 4. Analysis of the results of the manufacturing process; 5. Analysis of exploitation and disposal at end of life cycle; 6. Analysis of other phases that contribute to achieving castings; 7. Analysis of the entire process in terms of respecting the environment and sustainable development. The analysis method on a field belonging to the specific requirements of circular economy is made by analyzing a global event. This comprises the following stages: Establish specific criteria for the analyzed domain in relation to the circular economy; Specifying event works falling within the criteria set, which will be analyzed, and justification for selection.
