Introduction to Recycled Metal

What is/are Recycled Metal?

Recycled Metal - Moreover, a detailed discussion on the new applications of the recycled metals in different sectors will be provided. ^[1] Iron ore fines, coke breeze, limestone and dolomite along with recycled metallurgical wastes are converted into agglomerated mass at sinter plant. ^[2] This chapter will describe the activity of Fenix project that consisted in developing the hardware, infrastructure and processes to make possible the re-use of the recycled metals through an Additive Manufacturing (AM) method called Direct Ink Writing (DIW). ^[3] AFSD has the potential to produce ingots and components/builds from recycled metals (chips/scraps/wastes from industrial machining processes or municipal recycling centers). ^[4] Topics covered are minimum-quantity-lubrication (MQL), cryogenic-cooling and near-dry-machining; polishing slurries; recycled metals; processing wood materials; microfluidic paper devices; life-cycle-assessment; electrical-discharge-machining; friction-stir-processing; and green and/or cost-effective processes. ^[5] Replacing primary metals with recycled metals can reduce GHG emissions of vehicle production by about 7. ^[6] Test results proved that the recycled metal fillers enhance the electrical conductivity and enable EMI shielding. ^[7] Currently, recycled metal is diluted with primary metal to keep the concentration of alloying elements within specification. ^[8] This study provides a useful generic guide towards using recycled metal powders in the SLM processing, promoting an economic solution to industrial productions. ^[9] In addition, the presence of a noteworthy number of scrap metal fragments and the detection of low concentrations of arsenic and lead in most of the studied copper-tin alloy artefacts may suggest the possible use of recycled metal deriving from artefacts dating to earlier periods, namely the Early and Middle Bronze Age, which would originally have contained much higher concentrations of arsenic. ^[10] In early Earth history, initial enrichment in the upper mantle was arguably through mantle plumes that even recycled metals from the core-mantle boundary. ^[11] The article presents numerous structures of earthquake-resistant foundations that have been developed by the authors and other engineers over the past more than 30 years, in which recycled metal-cord tires are used. ^[12] The development of feasible, highly stable and easily recycled metal-free photocatalysts has drawn great attention for wastewater purification. ^[13] The equal channel angular pressing (ECAP), a severe plastic deformation technique, was recently used to produce bulk and light recycled metal chips, such as porosity-free and ultra-fine-grained aluminium nanocomposites (ANCs). ^[14] The purpose of this study is to propose an identification method for different nonferrous metal scraps, facilitate the further separation of nonferrous metal scraps, achieve better management of recycled metal resources and increase sustainability. ^[15] The recycled metals are the major source of both economic and environmental benefits at present due to the huge amount, but the recycled cathode active materials will be more valuable with the development of traction batteries. ^[16] Although Al is one of the most recycled metal streams, the presence of impurities, such as iron, silicon and copper, has limited the environmental and economic benefits of recycling Al. ^[17] The facile synthetic method is enabled for scalable production using recycled metal waste. ^[18] The results show the amount of recycled metals were equal if the tailings were leached by mixed cultures of Leptospirillum ferriphilum and Acidithiobacillus thiooxidans at three different ratios or by pure culture of L. ^[19] For this purpose, samples of composites based on recycled metal materials were prepared. ^[20] Results and discussions: this chapter discusses the effectiveness of the use of a gas piston cogeneration plant on the example of a company engaged in the processing of recycled metal. ^[21] LCIA methods that characterise functionally recycled metals as important, result in larger impact reduction, since these emphasise the merits of steering flows into state-of-the-art recycling. ^[22] Recycled metals have become a significant source of supply, with a lower environmental impact than primary metals. ^[23] The treatment of end-of-life vehicles generates large amounts of automobile shredder residue (ASR), a potential source of recycled metals. ^[24] The problem of using recycled metal is considered. ^[25] Several methods and technologies are developed to recycle metal containing wastes but almost all of them require the preliminary preparation of wastes resulting in an increased price of the recycled metals. ^[26] The advantages that could be gained from using recycled waste material such as recycled aggregates, recycled glass, recycled paper, recycled plastic, recycled metal, recycled textile and recycled fiber in construction products are the clean environment, the decreased utilization of natural resources and dumping places. ^[27]
