Claim Text:
1. A emission gas treatment method for recovering a recycle feed containing boron from emission gas discharged by a glass melting furnace for melting a boron-containing glass raw material, the emission gas treatment method comprising: a collection step of obtaining collected powder by collecting a component containing boron from the emission gas by a dry process; a mixing step of obtaining a collected powder-containing solution by mixing the collected powder in a solution; a separation step of separating the collected powder-containing solution into a solid and a liquid; a solution formation step of obtaining a boron solution by removing an impurity from an extracted liquid obtained in the separation step and supplying the boron solution as the solution in the mixing step; and a recovery step of recovering the recycle feed from an extracted solid obtained in the separation step.
