Ti has excellent properties but is more expensive than other materials due to its high melting point, reactivity and difficult processability. One way lower the production cost of products recycle scraps. Before recycling scraps, pretreatment remove contamination essential. scraps can be pretreated in an alkaline solution, thus eliminating use acidic solutions. However, a only involving immersi...

This chapter describes the methodology used in EPA's Waste Reduction Model (WARM) to estimate streamlined life-cycle greenhouse gas (GHG) emission factors for yard trimmings and food scraps beginning at the point of waste generation. The WARM GHG emission factors are used to compare the net emissions associated with these two organic material types in the following three materials management op...

Abstract Silicon was recovered from solar cell Si scraps through 42.5 mol% SiO 2 –42.5 CaO–15 Al O 3 slag refining. The motion behaviors of N 4 and SiC were observed in situ real-time using a high-temperature laser confocal microscope, the recovery refining carried out at 1,500°C for 30 min. Results indicated that both inclusions concentrated slag, this work provides clear framework recycling r...
