中文简体1. Substantial reduction in the use of chemical reagents
Traditional bamboo fiber production mostly adopts chemical methods. In this process, the use of a large number of chemical reagents has become a major environmental problem. In order to successfully extract fiber from bamboo, the bamboo needs to be soaked in a solution containing a variety of chemical substances such as sodium hydroxide and sodium sulfide. The non-fiber components such as lignin and hemicellulose in the bamboo are dissolved through chemical reactions, and then the bamboo fiber is separated. However, although this method is effective in fiber extraction, the involvement of a large number of chemical reagents has brought many disadvantages.
The production of chemical reagents itself is a high-energy and high-pollution process. The production of these reagents consumes a lot of energy resources, and a large amount of waste gas, wastewater and waste residue will be emitted during the production process. These pollutants have caused serious pollution to the atmosphere, water bodies and soil environment. In the process of bamboo fiber extraction, the chemical solution after use contains a large amount of harmful substances. If it is directly discharged without proper treatment, it will cause irreversible damage to the surrounding ecological environment, especially water bodies and soil.
In sharp contrast, the innovative bamboo fiber production process has achieved a significant reduction in the use of chemical reagents. The new process abandons the mode of over-reliance on chemical reagents in traditional chemical methods, and instead adopts a combination of physical and mechanical methods and biological enzymatic methods. In the physical and mechanical method stage, the fiber components in the bamboo are initially separated by fine crushing and grinding of the bamboo, and almost no chemical reagents are used in this process. The subsequent biological enzymatic method uses specific enzymes to decompose and remove non-fiber impurities in the bamboo, which greatly reduces the use of chemical reagents compared to traditional chemical methods. Compared with traditional chemical methods, the use of chemical reagents can be reduced by dozens of times or even more. This significant reduction reduces the pollution to the environment during the production and use of chemical reagents from the source, laying a solid foundation for improving the environmental benefits of the bamboo fiber series.
2. Significant reduction in waste emissions
With the significant reduction in the use of chemical reagents, the waste emissions in the bamboo fiber production process have also been significantly reduced. When producing bamboo fiber by traditional chemical methods, the use of a large number of chemical reagents not only causes the chemical solution after use to become wastewater containing a variety of harmful substances, but also produces a large amount of waste residue during the treatment process. At the same time, chemical reagents may also produce some waste gas during the reaction process, which often contains substances that are harmful to the environment.
If these wastewater, waste gas and waste residue are not handled properly, they will cause serious harm to the environment. Direct discharge of wastewater will pollute rivers, lakes and other water bodies, affect the survival of aquatic organisms, and destroy the water ecological balance; random stacking of waste residues will occupy a large amount of land resources, and the harmful substances in them may penetrate into the soil, pollute the soil, affect the fertility of the soil and the growth of crops; the emission of waste gas into the atmosphere will aggravate air pollution and have a negative impact on human health and the climate environment.
Under the innovative process, due to the reduction in the use of chemical reagents, the amount of wastewater, waste gas and waste residue generated in the production process is also greatly reduced accordingly. First, the amount of chemical solution after use is greatly reduced, and the content of harmful substances in the solution is also significantly reduced, which makes wastewater treatment less difficult, and environmental protection emission standards can be met after simple treatment. Secondly, the physical and mechanical method and the biological enzymatic method are relatively mild during the reaction process, the amount of waste gas generated is very small, and the types and contents of pollutants in the waste gas are also greatly reduced. Furthermore, the amount of waste residue generated has also been significantly reduced due to the reduction in the use of chemical reagents. The reduction in the emission of these wastes has greatly reduced the pressure on the environment, making the advantages of the bamboo fiber series in environmental protection more prominent.
3. Significant reduction in energy consumption
In addition to reducing the use of chemical reagents and waste emissions, innovative processes also have obvious advantages in energy consumption. When producing bamboo fiber by traditional chemical methods, chemical reaction conditions such as high temperature and high pressure are required to promote the full reaction of chemical reagents with bamboo, which consumes a lot of energy. Not only is the energy consumption of chemical reagent production huge, but the energy consumption required to maintain reaction conditions during the bamboo fiber extraction process should not be underestimated.
The new physical and mechanical method combined with the biological enzymatic method has achieved a significant reduction in energy consumption. The physical and mechanical method mainly uses mechanical equipment to crush and grind bamboo for physical treatment. Although these equipment consumes a certain amount of energy, compared with the high temperature and high pressure reactions in traditional chemical methods, energy consumption has been greatly reduced. Moreover, in the physical and mechanical method, some energy-saving technologies are adopted, such as low-temperature grinding technology, which can not only avoid damage to bamboo fiber caused by high temperature generated by friction, but also reduce energy consumption to a certain extent.
The advantages of bio-enzymatic hydrolysis are more prominent. As a highly specific biocatalyst, enzymes can accelerate chemical reactions under mild conditions, that is, at room temperature and pressure. Compared with the reaction conditions of high temperature and high pressure required in traditional chemical methods, bio-enzymatic hydrolysis does not require a lot of energy to maintain the reaction environment. This significant reduction in energy consumption not only reflects the environmental protection characteristics of the innovative production process of bamboo fiber, but also reduces production costs and improves economic benefits for enterprises. At the same time, from a macro perspective, reducing energy consumption helps to ease the global energy shortage and has far-reaching significance for environmental protection and sustainable development.
4. The far-reaching impact of the comprehensive improvement of environmental protection benefits
The increasingly significant environmental benefits of the bamboo fiber series have brought about far-reaching impacts in many aspects. From the enterprise level, although the use of innovative processes to produce bamboo fiber may require a certain amount of R&D and equipment renewal costs in the early stage, in the long run, due to the reduction in the use of chemical reagents, the reduction in waste emissions and the reduction in energy consumption, the production costs of enterprises can be reduced. At the same time, the company actively adopts environmentally friendly production technology, fulfills social responsibilities, improves corporate image, and enhances market competitiveness. Consumers are increasingly inclined to choose environmentally friendly products. By producing environmentally friendly bamboo fiber products, the company can better meet market demand and win the trust and favor of consumers.
