Recycling titanium scraps through hydrogenation offers a sustainable approach to repurpose valuable material for additive manufacturing applications. The hydrogenation-dehydrogenation (HDH) process is central to this effort, allowing titanium scraps to be converted into usable powder for 3D printing and other AM techniques.

Conduct an extensive literature review covering the hydrogenation-dehydrogenation process as applied to titanium scraps for recycling. The review will explore key aspects such as hydrogen embrittlement mechanisms, powder morphology and quality requirements for AM, and comparative performance of recycled HDH powder Compile findings into a structured report, identifying the key challenges and benefits of using recycled titanium in AM.

Aufgrund der edlen Natur von Gold ist eine gezielte Rückgewinnung aus Elektroschrott wegen der höheren Reaktivität anderer Metalle eine Herausforderung. Derzeitige hydrometallurgische Ansätze zur Goldgewinnung aus PCBs erfordern immer mehrere Schritte, was zu Verlusten führt. Ziel dieser Studie ist es, eine direkte Laugungsmethode zur Rückgewinnung oberflächlichen Goldes zu finden.
