In the paper, the present situation and malpractice of utilizing coal gangue to make hollow brick were simply introduced, the actual plight and countermeasures of pulping and papermaking industry were expounded, the ammonium sulfite ((NH 4) 2SO 3 ) pulping process was compared with the traditional soda pulping process in detail. The solution was put forward that the hyper-gravity technique is used to recover the SO 2 from the flue gas produced by making brick with coal gangue, so as to produce the (NH 4) 2SO 3 reagent needed by the (NH 4) 2SO 3 pulping process of papermaking, extricate papermaking industry from the straitened circumstances of the shortage of the resource, establish a green industrial chain, utilize the resource to the utmost, reduce the unfavorable influences on environment, and realize the sustainable development of industry.
