In order to achieve the energy-saving and climate targets, it is not only necessary to develop new processes and processing possibilities, but also to optimise known process chains with regard to energy and resource efficiency in the area of production technology. Here, the recycling of supposed production waste represents an opportunity to save energy. In addition to the conventional and smelting metallurgical recycling process, extensive research activities have therefore been carried out for alternative solid-state recycling processes. One example is the friction-induced recycling process, which has been used in past studies to demonstrate the energy- and resource-efficient production of semi-finished products from aluminium scrap such as chips. In addition, properties like chemical composition and strength can be adjusted locally and in terms of processing time. This can be used to improve the versatility of further processing steps."}],"publication":"Lecture Notes in Mechanical Engineering","type":"book_chapter","language":[{"iso":"eng"}],"department":[{"_id":"156"}],"user_id":"83141","_id":"46752","project":[{"_id":"147","name":"TRR 285 – C03: TRR 285 - Subproject C03"}]},{"date_created":"2023-10-02T06:59:53Z","publisher":"Springer Science and Business Media LLC","title":"Potentials of a friction-induced recycling process to improve resource and energy efficiency in manufacturing technology","issue":"6","quality_controlled":"1","year":"2023","language":[{"iso":"eng"}],"keyword":["General Materials Science"],"publication":"International Journal of Material Forming","abstract":[{"lang":"eng","text":"<jats:title>Abstract</jats:title><jats:p>Efforts to enhance sustainability in all areas of life are increasing worldwide. In the field of manufacturing technology, a wide variety of approaches are being used to improve both resource and energy efficiency. Efficiency as well as sustainability can be improved by creating a circular economy or through energy-efficient recycling processes. As part of the interdisciplinary research group \"Light—Efficient—Mobile\" investigations on the energy-efficient friction-induced recycling process have been carried out at the department of Forming and Machining Technology at Paderborn University. E.g. using the friction-induced recycling process, different formless solid aluminum materials can be direct recycled into semi-finished products in an energy-efficient manner. The results of investigations with regard to the influence of the geometrical shape and filling rate of the aluminum particles to be recycled as well as the rotational speed of the continuously rotating wheel are explained in this paper. In addition to the recycling of aluminum chips, aluminum particles like powders from the field of additive manufacturing are processed. Based on these results, the future potentials of solid-state recycling processes and their contribution to the circular economy are discussed. The main focus here is on future interdisciplinary research projects to achieve circularity in the manufacturing of user-individual semi-finished products as well as the possibility to selectively adjust the product properties with the continuous recycling process.</jats:p>"}],"author":[{"first_name":"Thomas","last_name":"Borgert","full_name":"Borgert, Thomas","id":"83141"},{"full_name":"Milaege, Dennis","last_name":"Milaege","first_name":"Dennis"},{"first_name":"Swetlana","last_name":"Schweizer","full_name":"Schweizer, Swetlana","id":"8938"},{"first_name":"Werner","last_name":"Homberg","id":"233","full_name":"Homberg, Werner"},{"first_name":"Mirko","last_name":"Schaper","full_name":"Schaper, Mirko","id":"43720"},{"first_name":"Thomas","last_name":"Tröster","id":"553","full_name":"Tröster, Thomas"}],"volume":16,"date_updated":"2025-06-06T08:18:51Z","doi":"10.1007/s12289-023-01785-w","publication_status":"published","publication_identifier":{"issn":["1960-6206","1960-6214"]},"citation":{"ama":"Borgert T, Milaege D, Schweizer S, Homberg W, Schaper M, Tröster T.

In order to increase the sustainability of forming processes it would be favorable if the forming of workpieces becomes possible using production waste. At the Chair of Forming and Machining Technology of the Paderborn University (LUF) research is presently conducted with the overall goal to produce workpieces directly from secondary aluminum (e.g., powder and chips). Therefore, friction-based forming processes like friction spinning (or cognate processes) are used due to their high efficiency. As a pre-step, the production of semi-finished parts was the subject of accorded research work at the LUF. Therefore, a friction-based hot extrusion process was used for the full recycling or rework of aluminum chips into profiles. Investigations of the recycled semi-finished products show that they are comparable to conventionally produced semi-finished products in terms of dimensional stability and shape accuracy. An analysis of the mechanical properties of hardness and tensile strength shows that a final product with good and homogeneously distributed properties can be produced. Furthermore, significant correlations to the friction spinning process could be found that are useful for the above-mentioned direct part production from secondary aluminum.</jats:p>"}],"status":"public"}]
