Bio-based PTT fiber uses 1,3-PDO from biomass conversion, which not only combines the excellent properties of other fibers such as polyester and nylon, but also is a recyclable green fiber. Compared with traditional chemical synthesis methods, biological methods It has the advantages of renewable raw material sources, mild reaction conditions, good selectivity, less by-products, and less environmental pollution.
Previously, the production technology of bio-based PDO and PTT fibers has been monopolized by foreign companies. Until 2014, Shenghong Group cooperated with Tsinghua University to develop biomaterial fibers, successfully breaking the foreign technology monopoly on the PTT industry, and developed a complete set of production technology for bio-based PDO and PTT fibers with completely independent intellectual property rights, becoming the first domestic company. , the second PTT fiber manufacturer in the world with a complete industrial chain.
Shenghong is currently the largest bio-based PDO and PTT fiber manufacturer in China, setting a number of records in the history of the world's textile PTT technology. The whole life cycle of the PTT fiber products produced from raw materials to manufacturing, use, and recycling is green and recyclable, and the carbon emissions of the product life cycle are reduced by 15%.
Since the 18th National Congress of the Communist Party of China, the construction of ecological civilization has been written into the five-in-one overall layout. In 2020, China clearly put forward the "two-carbon" goal. The "Guiding Opinions" released this time also clearly proposed to expand the production of green fibers and build a clean, low-carbon, and circular green manufacturing system.
In response to the national ecological civilization construction and the "dual-carbon" goal, in recent years, Shenghong has been guided by ecological strategies, and has made every effort to build a world-class green product system, lead the green transformation and development of the industry, and create an ecological, low-carbon and circular "green Shenghong". "the road.
In Suqian Shenghong New Material Industrial Park, Shenghong invested in the construction of the world's first regenerated melt direct spinning production line from bottle flakes to spinning. Plastic bottles, accounting for 20% of the national total recycling, are equivalent to saving 3.8 million tons of crude oil after being recycled.
In Lianyungang Shenghong Petrochemical Industrial Park, accelerate the construction of three "million-ton" green projects, namely, million-ton EVA photovoltaic material, million-ton acrylonitrile, and million-ton green degradable materials, leading the industry to value The high-end extension of the chain will promote the transition of clean energy.
At present, the annual production capacity of Silbong Petrochemical under Shenghong reaches 300,000 tons, accounting for 16% of the total domestic production capacity. Among them, the photovoltaic-grade EVA production capacity exceeds 200,000 tons, accounting for 25.6% of the global photovoltaic-grade EVA production, ranking first in the world. The downstream products of acrylonitrile are widely used in high-end fields such as large-scale wind power, aerospace, and high-speed rail. At present, the overall production capacity of Sierbang acrylonitrile is 780,000 tons/year, ranking first in China, accounting for 22% of the total domestic production capacity. The million-ton-level green degradable material directly points to the "double carbon" goal.
Accelerating the green transformation is not only an inevitable requirement for enterprises to enhance their competitiveness, but also the core of China's manufacturing industry to continuously strengthen its international competitiveness. Sheng Hong clearly proposes to speed up the construction of a world-class enterprise with global competitiveness, act as the leader of the "dual carbon" goal, make "green, low-carbon and recycling" the core competitiveness of the enterprise, and develop a sustainable high-quality development model. Actively participate in global competition and contribute green power to the transformation and upgrading of China's manufacturing industry!
