In the current context of increasing environmental awareness, the tissue production industry is actively exploring innovative processes to achieve the goal of energy conservation and emission reduction.

As the global attention to environmental protection continues to deepen, all industries are actively seeking ways for green development, and the tissue production industry is no exception. Recently, many tissue production enterprises have introduced innovative processes, which not only improve production efficiency but also significantly reduce the impact on the environment.​

In terms of energy utilization, a new technology called "high - efficiency heat recovery system" has been widely applied. In the traditional tissue production process, a large amount of heat energy is required for the paper drying process, and most of the heat is directly discharged into the atmosphere after the drying task is completed, resulting in serious energy waste. The new heat recovery system is designed with high - efficiency heat exchangers installed on the exhaust gas pipelines of the paper drying equipment. These heat exchangers can transfer the heat in the exhaust gas to the cold air or cold water entering the drying equipment, pre - heating or pre - warming them before they enter the drying process. As a result, the additional energy required for the drying process is greatly reduced. According to actual data, after adopting this heat recovery system, a medium - sized tissue production enterprise can save hundreds of tons of standard coal in energy consumption annually, and correspondingly reduce a large amount of greenhouse gas emissions such as carbon dioxide.​

In addition to energy recovery, there has been a major breakthrough in water resource utilization. In the past, processes such as pulp washing and screening in tissue production required a large amount of water, and the used water often contained a large number of suspended solids and chemical agents. If directly discharged, it would cause serious pollution to water bodies. Now, an advanced "reclaimed water reuse" technology has been applied to the production process. This technology first purifies the wastewater generated in the production process through a series of physical and chemical treatment methods, removing impurities and harmful substances in it, so that the treated water meets certain water quality standards. Then, this purified "reclaimed water" is re - conveyed to the production process and used in processes with relatively low water quality requirements, such as rough washing in the early stage of pulp washing. Through this reclaimed water reuse system, the fresh water intake of enterprises can be reduced by more than half, greatly alleviating the pressure of water resource shortage and reducing the pollution of wastewater discharge to the environment.​

In the core link of the production process - the operation of the paper - making machine, there have also been innovative improvements. The new paper - making machine adopts more advanced variable - frequency speed - regulation technology and intelligent control system. The variable - frequency speed - regulation technology can accurately adjust the running speed of each component of the paper - making machine according to the actual needs of paper production, avoiding energy waste caused by the fixed speed of traditional equipment during operation. When producing tissues of different specifications and thicknesses, the system can automatically adjust the rotation speed and pressure of the paper - making machine to ensure that while meeting production requirements, energy consumption is minimized. The intelligent control system can monitor the running status of the paper - making machine in real - time through sensors. Once it is found that the equipment has abnormalities or high energy consumption, it can be automatically adjusted and optimized in a timely manner to ensure the efficient and stable operation of the production process. The comprehensive application of these technologies has increased the production efficiency of the paper - making machine while reducing energy consumption by about 20%.​

The application of innovative processes not only helps tissue production enterprises achieve the goal of energy conservation and emission reduction but also provides strong support for the improvement of product quality. The optimized production process has significantly improved the softness, water absorption, and strength of the produced tissues. While consumers enjoy high - quality tissue products, they also indirectly contribute to environmental protection. With the continuous promotion and improvement of these innovative processes, it is believed that the tissue production industry will take more solid steps on the path of sustainable development and contribute more to the green future of the earth.
