“…The scrap material is first compacted to form a billet. The billet is preheated before the extrusion [260]. The force applied on the ram pushes the billet on the die to extrude the part, as can be seen in Figure 25.…”

“…Recycling aluminum using conventional methods using melting requires 25 times more energy than that needed for primary steel production. To overcome this problem, Pantke et al [260] recycled aluminum scrap of AA-7175 and AA-7475 using hot extrusion process without remelting. Haase et al [261] recycled machined AA6060 aluminum alloy chips using hot extrusion and subsequent cold extrusion.…”

To improve the microstructure and mechanical properties of fundamental materials including aluminum, stainless steel, superalloys, and titanium alloys, traditional manufacturing techniques have for years been utilized in critical sectors including the aerospace and nuclear industries. However, additive manufacturing has become an efficient and effective means for fabricating these materials with superior mechanical attributes, making it easier to develop complex parts with relative ease compared to conventional processes. The waste generated in additive manufacturing processes are usually in the form of powders, while that of conventional processes come in the form of chips. The current study focuses on the features and uses of various typical recycling methods for traditional and additive manufacturing that are presently utilized to recycle material waste from both processes. Additionally, the main factors impacting the microstructural features and density of the chip-unified components are discussed. Moreover, it recommends a novel approach for recycling chips, while improving the process of development, bonding quality of the chips, microstructure, overall mechanical properties, and fostering sustainable and environmentally friendly engineering.
