A beautifully crafted, complete book is primarily produced through three major processes: plate-making, printing, and binding. Among these, binding is the final step—complex not only in its variety of tasks but also in the wide range of machinery types and models used, along with numerous processing methods, making it an artful and intricate operation. During the binding process, depending on the specific stage, significant amounts of dust and paper trimmings are generated—particularly during activities like back milling, grooving, and cross-cutting (center sawing). Additionally, some dust and paper scraps are produced during gluing operations such as three-sided trimming for perfect binding, three-sided trimming for saddle stitching, and edge-finishing machine processes. Traditionally, these paper trimmings and dust have been handled by using fans to transport them via ducts directly to a waste-paper room, where they eventually settle, get collected, and packaged for disposal.

　　The dust management issues prevalent in most printing companies

　　Most printing companies face the following issues when it comes to dust control for printing and binding waste materials.

　　(1) There is neither a paper-edge collection and packaging system nor a dust-control system—instead, paper edges and dust are directly blown into the packing room, where they naturally settle.

　　(2) The cyclone separator used for paper edges and dust fails to effectively remove them, resulting in significant amounts of air and dust escaping through gaps in the baling machine and spreading throughout the waste paper room and workshop. Moreover, large quantities of dust are carried by the airflow and released outdoors, contaminating the surrounding environment.

　　(3) The dust removal system operates under positive pressure, causing dust to fly around uncontrollably.

　　(4) The dust removal system lacks safety protection measures, posing a significant safety hazard.

　　(5) The floor and walls of the waste paper room have significant dust accumulation.

　　(6) Electrical control equipment installed in the waste paper room is highly susceptible to safety hazards.

　　(7) Dust is primarily concentrated in the waste paper room, where dust levels are particularly high, creating a significant risk of safety hazards such as dust explosions and fires. Moreover, workers who spend extended periods in the waste paper room inhale large amounts of dust, increasing their likelihood of developing occupational diseases like silicosis—conditions that can severely harm operators' physical and mental health.
