The production of cardboard boxes primarily consists of three steps: one is the manufacturing of corrugated paperboard, which involves processing rolls of paper from paper mills through corrugated paperboard production equipment into various types of paperboard. The paperboard production process includes steps such as paper loading, glue application, bonding, drying, and cutting. The main pollutants generated during this process are waste paper, adhesive emissions, residual glue, volatile gases, and waste scraps.

Secondly, the process of cardboard printing, which includes printing, slotting, and die-cutting, generates pollutants such as ink wastewater, organic solvents, and industrial wastewater. Solid waste primarily consists of waste scraps, and there is also production noise.

The third aspect is the forming process of cardboard boxes, which involves converting pre-cut cardboard sheets into boxes through binding, followed by further adhesive bonding to produce the final product. This process generates relatively few pollutants, primarily consisting of waste glue and noise.

The paper box production mainly consists of three steps: 1. The production of corrugated paperboard, which involves processing the rolls of paper produced by paper mills into various types of corrugated paperboard through corrugated paperboard production equipment. The paperboard production process includes steps such as loading paper, applying glue, bonding, drying, and cutting. The main pollutants generated during this process are waste paper material, exhaust glue, leftover adhesive, volatile gases, and waste scrap.

Secondly, the cardboard printing process, which mainly includes printing, slotting, and die-cutting, generates pollutants such as ink wastewater, organic solvents, industrial wastewater, solid waste primarily consisting of waste edges and scraps, and production noise.

The third aspect is the process of paper box forming, where the die-cut cardboard is assembled and processed into boxes, followed by further bonding, ultimately forming the finished paper boxes. This process generates relatively few pollutants, primarily waste glue and noise.
