Possible technologies to recycle and purify SoG-Si wastes were reviewed: such as filtration, sedimentation, solidification control, electromagnetic separation, plasma oxidation, centrifugation, and high temperature remelting process, et al.enElectromagnetic separationsEnergy payback timeEnergy valueFinancial valuesHigh temperaturePlasma oxidationSolar grade siliconArticle
