Century Synthetic Fiber Corporation Saves Energy for Sustainable Development
Century Synthetic Fiber Corporation (STK) specializes in manufacturing and trading high-quality long filament yarns such as POY (Partially Oriented Yarn), DTY (Drawn Texturized Yarn), and FDY (Fully Drawn Yarn). The company’s products are input materials for textile manufacturers, especially producers of high-end sportswear fabrics. With a production capacity of over 60,000 tons of yarn per year, STK has established itself as a leading enterprise in the long filament yarn manufacturing sector in Vietnam.

STK is a market leader in the long filament yarn industry in Vietnam.
With the desire to produce high-quality products that meet market demand while being environmentally friendly, conserving materials, and minimizing production costs — especially electricity costs — STK has actively promoted energy-saving projects and the use of renewable energy.
According to the Ministry of Industry and Trade, the textile and garment sector still has an energy-saving potential of up to 20%. Therefore, technological innovation and technical improvements are key solutions to help textile enterprises use energy more efficiently, increase labor productivity, and enhance competitiveness.
Mr. Nguyen Van Hai, Head of the Utility Department at STK, said that to save electricity, the company has implemented a range of measures, including: investing in energy-saving equipment and technology, replacing outdated and power-hungry devices with newer ones, and designing factory buildings to maximize the use of natural lighting — creating a well-ventilated working environment while minimizing unnecessary use of electrical devices.
In addition, STK has deployed various energy-saving initiatives at its production facilities. Innovations such as installing inverters on machines and upgrading the compressed air system have helped the company save 2,643,058 kWh of electricity and reduce about 12,768 tons of CO₂ emissions from 2018 to 2023.
STK also places a strong focus on monitoring and evaluating energy usage at its production sites. In early 2024, the company’s Trảng Bàng branch conducted a greenhouse gas (GHG) inventory to identify current energy consumption sources and propose solutions for energy optimization. One implemented solution was replacing fluorescent lights with high-efficiency LED lights, saving approximately VND 115 million per year; another was installing inverters to control oil exhaust fans, saving about VND 350 million annually.
Moreover, STK performs periodic energy audits every three years. These reports help the company assess its current energy usage and identify inefficient areas, allowing for targeted improvements to reduce energy costs.

Rooftop solar power accounts for more than 6% of STK’s total energy consumption.
To reduce dependence on the national power grid, since 2020, STK has partnered with a strategic partner to install rooftop solar systems at its Củ Chi and Trảng Bàng plants. The total capacity of these solar power systems is 7.4 MWp per year. By 2023, solar energy accounted for more than 6% of the company’s total energy consumption. In the coming time, the company plans to increase its use of renewable energy through additional rooftop solar projects at the Unitex factory and DPPA (Direct Power Purchase Agreement) projects at both the Trảng Bàng factory and the Unitex subsidiary.

A company representative received the 2024 Energy Efficiency in Industry Award.
The investment in technological innovation, combined with the comprehensive implementation of energy-saving solutions, has helped Century Synthetic Fiber Corporation significantly reduce energy consumption, lower CO₂ emissions, and contribute to climate change mitigation.
In 2024, Century Synthetic Fiber Corporation was one of 11 enterprises awarded the “Industrial Energy Efficiency Award,” organized by the Ministry of Industry and Trade in collaboration with the Vietnam Energy Conservation and Efficiency Science and Technology Association. The award honors enterprises, projects, and individuals with outstanding initiatives and solutions in promoting efficient energy use, contributing to national energy-saving goals in accordance with Prime Minister’s Directive No. 20/CT-TTg. |

1H2024 Semi-annual Corporate governance report
Century: Risk management for sustainable development
With a solid foundation in reporting techniques, an abundance of available information as well as ongoing independent assurances, Century Synthetic Fiber Corporation (code STK) always maintains a good position in sustainability reporting polls.
For many years, Century has always shown its steadfastness with the goal of sustainable development and achieving worthy results. Typically, in the context of many challenges for the industry, Century is still showing flexible adaptation and good resilience, recording bright spots such as attracting orders for value-added recycled yarn. increased significantly with Japanese customers, continuing to expand the customer file with 12 new customers in the first 9 months of 2023.
These practical efforts are “recorded” and excellently conveyed by Century through annual reports and sustainable development reports, thereby providing to stakeholders and the public. Invest in a well-informed picture. That is also the main reason why the Company’s annual report reached the Top 20 best annual reports of 2023 in the non-financial group; continuously in the Top 10 best sustainable development reports – within the framework of the Listed Enterprise Voting, and this year, Century’s sustainable development report continues to be in the Top 5, achieving the category Award for Most Complete Report.
With the theme “Risk management for sustainable development”, Century continues to consistently demonstrate environmental and social risks as well as the ways the Company manages these risks. According to the assessment of the Voting Council, with the “solid” use of GRI reporting standards similar to previous years, Century has systematically demonstrated its initiatives and efforts in its sustainable development path.
In addition, Century has provided numerous guarantees for environmental and social reporting indicators. The assurance is done from many different sources and creates a relatively good level of reliability.
A new feature this year of Century is its participation in the project of disclosing its carbon emissions within the framework of the CDP project (Carbon Disclosure Project). Century is one of the very few listed businesses that disclose information under the CDP framework. Another strong point of Century is the publication of ESG indicators, especially environmental indicators, in a complete and highly quantified manner.
Notably, according to USFIA Benchmarking Study 2023, fashion brands have increased the proportion of purchases from Vietnam from 96% (2022) to 100% (2023). This result comes from the need to spread risks about the supply of input materials, so American fashion companies tend to move and seek supplies from many other countries, besides China.
Most of these brands have commitments and have carried out stronger communication campaigns about their responsibility towards the environment, human rights, and society. Therefore, Vietnamese businesses that meet ESG standards well, such as Century, will have a great opportunity to become strategic supply partners for this brand, thereby reaching out for development and integration as soon as market conditions are ripe.
According to Century’s roadmap, the Company continues to research and launch diverse, environmentally friendly, high-quality products, yarns with special features that create added value for consumers. uses (such as fire-resistant, highly elastic, moisture-absorbing, UV-resistant yarns…); continue to conquer and expand new markets in Europe, America, and Mexico (with direct export activities).
In addition, the Company also promotes sales in the form of on-site export to customers making fabrics for garment exports to the US, Canada, Europe, and Japan to welcome orders moving from China to Vietnam. In addition, the Company also plans to increase the proportion of renewable electricity in the total power supply to meet the goal of reducing greenhouse gases and gradually making a commitment to reduce greenhouse gases under the SBTi initiative.
For the Unitex project, it is being implemented on schedule to complete the import of machinery in the first quarter of 2024 and complete construction at the end of the quarter. Unitex factory phase 1 (36,000 tons/year) is expected to begin operating in the second quarter of 2024. This is a project that many analysts expect, when put into operation, will help Century increase its total capacity to 96,000 tons/year to anticipate the growing demand for recycled and virgin yarn, in both markets. export and domestic markets. It is expected that when the Unitex factory is completed in 2025, Century will become the second largest yarn manufacturer in the country.
This will be the premise for Century to catch up with the green fashion trend when major brands commit to taking action to combat climate change and use recycled yarn at a rate of 50 – 100% by 2025 and reserve resources to prepare for the time the market recovers.
