"

　　 According to the report, in 2021, the output of regenerated cellulose fiber of Sanyou chemical fiber will reach 681700 tons, with the main business income of 8.28 billion yuan and the gross profit rate of 11.97%; Environmental protection investment is about 369 million yuan, realizing comprehensive energy consumption of 820.4kgce/t and water consumption of 34.2m 3/ t. The total sulfur recovery rate was 97%, and the recovery rate of Na Ψ so ? was 66.3%. The product competitive advantage and green development level were further improved. Through this beautiful report card, the key points of Sanyou chemical fiber's pioneering and innovative development are intertwined and overlapped with each other, providing a reference sample for the "double carbon" development of the industry.

　　 Focus on pulp:

　　 Improve the anti risk ability of raw material procurement

　　 Pulp is an important raw material for the production of regenerated cellulose fiber, and its green procurement and stable production are important for Sanyou chemical fiber to realize sustainable development. Due to the different sources of pulp, there are great differences in pulp performance indicators. How to comprehensively evaluate the advantages and disadvantages of various pulps in the selection of raw materials and carry out reasonable collocation will directly affect the fiber spinning and the properties of regenerated cellulose fiber. Sanyou chemical fiber deeply studies all kinds of pulp, studies and analyzes the tree species, production technology, internal indicators and production line trial, establishes pulp data files, formulates the mixing scheme of different varieties of pulp, and develops stable production process by optimizing and adjusting the glue making process and spinning process. At present, Sanyou chemical fiber has successfully applied a variety of different pulps to produce regenerated cellulose fiber, and explored the matching process route suitable for waste textile pulp, which provided more technical support for the realization of sustainable raw materials and improved the anti risk ability of raw material procurement of enterprises.

　　 At the same time, Sanyou chemical fiber actively promotes responsible procurement, providing new impetus for the development of enterprises. Over the years, Sanyou Chemical Fiber Co., Ltd. has actively cooperated with canopy to publicize pulp procurement policies, and completed the second canopy audit in 2019, becoming the first renewable cellulose fiber enterprise in China to obtain the "green shirt" rating in the button ranking released by canopy. In 2021, Sanyou chemical fiber will continue to strengthen the procurement management, further improve the "management measures for supplier evaluation and admittance" and "pulp procurement policy", conduct a comprehensive evaluation on suppliers, and specify the requirements for purchasing FSC certified pulp and recycling cotton pulp after consumption in the purchase and sale contract signed with the supplier. In November 2021, the canopy button ranking report in 2021 announced that Sanyou chemical fiber obtained 27.5 buttons, 5.5 more than that in 2019, and obtained the "partial dark green shirt" rating, effectively improving the brand value of fiber.

　　 Closed loop production:

　　 Carry out energy conservation and emission reduction and circular economy to the end

　　 As the chairman unit of the green development alliance of renewable cellulose fiber industry (hereinafter referred to as "CV alliance"), Sanyou chemical fiber, referring to the requirements of "alliance roadmap 2025", uses the requirements of domestic and foreign advanced standard system to continuously improve the level of enterprise clean production and promote industrial closed-loop production. In terms of energy conservation and emission reduction, Sanyou Chemical Fiber Co., Ltd. focuses on promoting projects such as "increasing production of hemicellulose sugar production line", "Application Research of submerged steam mixer", "Upgrading Research and development of flash evaporation energy saving", "low consumption operation research on alkali washing of sulfur-containing waste gas and carbon disulfide desorption", "technical research on improving the condensation recovery efficiency of CS Theil", "Research on efficient separation technology of wastewater containing carbon disulfide" and "research and development of high-efficiency push flow aeration system", Good economic and social benefits have been achieved. For example, in 2021, Sanyou chemical fiber independently designed and developed a new type of high-efficiency double-layer stacked network disk structure condenser officially put into use. The condensation principle is that the water drops from the tray hole to form a uniform water curtain. By optimizing and adjusting the condensation process, the effect of sufficient condensation can be achieved. The condensing effect of the new type of net disk condenser is obviously improved, and the recovery amount of CS Ψ per ton silk is increased by 0.5kg, thus the production cost and total carbon emission are reduced.

　　 In terms of circular economy, Sanyou chemical fiber is the core node of Tangshan Sanyou Group Co., Ltd. from upstream chemicals (soda ash, chlor alkali, silicone, etc.) to consumer goods. Taking advantage of its own industrial network advantages, Sanyou chemical fiber creatively uses the by-products or wastes produced by one enterprise as the raw materials of another enterprise, realizing the closed-loop utilization of material and multi-level utilization of energy, and building a circular economy system of collaborative innovation of multi industry chains. For example, the by-product of the production of regenerated cellulose fiber, Na Ψ so ?, has been concerned by stakeholders in recent years, but its low economic value limits its recovery and reuse. Sanyou chemical fiber just relies on the group's circular economy system to recycle Na Ψ so ? solution for soda ash production, which reduces the steam and power consumption of Na Ψ so ? crystallization recovery.

　　 Carbon reduction practice:

　　 From calculating carbon footprint of products to improving carbon reduction standard system

　　 The environmental and ecological risk caused by global warming is one of the serious threats to human survival in the century. Reducing carbon dioxide emissions has become a common responsibility and strategic measure of all countries and regions in the world. China's commitment to the world's carbon peak, carbon neutral, requires the textile industry to set an example of green change and responsibility practice, and integrate the environmental responsibility of the industry into the industrial value system, innovation system and management system, so as to effectively drive the green transformation and development of the industry.

　　 In this context, Sanyou chemical fiber will officially promote the transformation and upgrading and carbon reduction process in 2021, and put forward the vision goal of "achieving 30% carbon emission reduction per unit product by 2030 and achieving carbon neutrality by 2055". On this basis, Sanyou chemical fiber joined the "30.60 China Textile and clothing carbon neutralization acceleration action", further carried out climate training camp, regularly carried out carbon verification and information disclosure, and further developed a more specific dual carbon action plan and roadmap. It is worth mentioning that in 2021, Sanyou chemical fiber completed tangsi relying on the traceability industrial chain under construction ? Carbon footprint calculation, based on the whole life cycle methodology, on the basis of tracing the proportion of carbon emissions in each stage, in-depth research and development of low-carbon tangsi can reduce the carbon emissions of downstream processing process ? Products.

　　 Based on Tang silk ? Sanyou chemical fiber disclosed the relevant data in the report on the carbon footprint analysis of products from cradle to gate. According to the calculation, 1kg tangsi ? EcoTang ? The greenhouse gas emission of the product is 4.29kgco Theil EQ, the cumulative energy demand is 35.73mj and the water consumption is about 0.105m 3。 For CV alliance to include carbon emissions into the "alliance roadmap 2025" assessment requirements, Sanyou chemical fiber also disclosed the carbon emission data per ton of products in its key performance - 3.11tco Theil Eq.

　　 In addition, in the practice of carbon reduction, Sanyou chemical fiber found that the comparability of carbon emission data among different enterprises is relatively poor due to the influence of system boundary construction, activity data selection, carbon footprint allocation, secondary data selection, biochar and other factors. Therefore, Sanyou chemical fiber, together with China Chemical Fiber Industry Association and CV alliance, jointly promote the establishment of carbon accounting rules based on chemical fiber industry and regenerated cellulose fiber, and provide standard guarantee for different enterprises to benchmarking and learn from each other's emission reduction experience by improving carbon verification standards in the field of renewable cellulose fiber.

　　 Brand upgrade:

　　 Building traceability product matrix

　　 Since 2019, Sanyou chemical fiber has launched tangsi ? Tangcell ? High end environmental protection brands have taken the step of transformation from production-oriented manufacturing enterprises to value-oriented brand enterprises. In 2021, Sanyou chemical fiber will focus on tangsi ? EcoTang ? The green industrial chain under the guidance of products is to ensure the green transparency of the industrial chain and ensure the production process to be more low-carbon and traceable in the whole life cycle.

　　 To ensure tangsi ? EcoTang ? For the traceability of products, Sanyou chemical fiber has independently developed molecular tracking technology and detection method with special components after tackling key scientific problems. Tangsi ? The special tracer will not disappear in the production process. Even after textile processing and transformation through the industrial value chain, the whole process identification of products can be realized, and the complete transparency and traceability of fiber brands and consumers in finished clothing can be ensured. For all kinds of products (including fiber, yarn, cloth, clothing, etc.) in the process of industrial chain processing, Sanyou chemical fiber is equipped with customized special testing equipment, and professionals are arranged to test and issue test reports to ensure that retailers, brands and consumers can timely and accurately identify whether there is Tang silk in textiles ? Environmentally friendly ingredients.

　　 In addition, in the tangs ? Tangcell ? In the brand matrix, Sanyou chemical fiber has successively developed differentiated products with different raw material sources, various functions and colors, and suitable for different application fields, such as tangsi ? EcoTang ?、 Tangsi ? Caixian, tangsi ? Lyocell fiber, tangs ? Zhudale, etc., constantly enrich the green connotation of the brand.

　　 At the same time of brand upgrading, Sanyou chemical fiber has always maintained the communication and cooperation with the upstream and downstream of the industrial chain, conveying the life concept of "better life, tangsi sharing".
