In a world increasingly affected by climate change and resource shortages, the need for sustainability has never been more urgent. For Taiwan, renowned as the Textile Kingdom, this presents a unique opportunity to harness its remarkable creativity for the greater good.
Taiwan's textile industry has successfully evolved from a mature, labor-intensive sector into a dynamic field focused on advanced technology and functional textiles. This transformation has led to the development of numerous eco-friendly yarns and textiles, including a range of innovative products crafted from recycled materials such as plastic bottles and discarded fishing nets.

Inspired by Local Wisdom: Using Oyster Shells in Textiles

Located in Tainan, Creative Tech Textile is committed to producing environmentally-friendly products. However, when Chairman Wang Yeh-hsun introduced clothing made from recycled PET bottles over a decade ago, he encountered a significant challenge: While surveys indicated that consumers approved of and supported eco-friendly materials, the prices of these garments were 30 to 50 percent higher than those of conventional apparel. This price disparity posed a considerable obstacle to the promotion of sustainable products.
"If consumers can't see the value and benefits of eco-friendly products, this will be a barrier to acceptance and sustainability."

To enhance the competitiveness of eco-friendly textiles, Wang Yeh-hsun came up with the innovative idea of utilizing the oyster shells that are plentiful in his hometown.
"In Yunlin, where I grew up, back before the introduction of quicklime, people plastered their walls with lime from burnt oyster shells. The lime plaster made homes warm in the winter and cool in the summer. I wanted to see if I could use oyster shells in textiles," he said.

As a result, Creative Tech collaborated with Taiwan's Industrial Technology Research Institute (ITRI) and various universities of technology on a project that incorporated oyster shells into textiles. After three years of intensive research and development, this initiative successfully produced "Seawool," a material that combines the soft texture of wool with an elegant luster.

This research and development project revealed that oyster shells possess not only very low thermal conductivity but also antibacterial, anti-odor, and anti-static properties. Additionally, incorporating oyster shells into textiles can help reduce carbon emissions and minimize plastic usage, making the resulting products more environmentally friendly.
The key to unlocking the benefits of oyster shells lies in the processing temperature and the fineness of the powder. To guarantee the highest quality raw material, Creative Tech has invested in a nano-grade milling plant. Their proprietary nano-particle dispersion technology ensures that the nano-grade oyster shell powder is evenly distributed throughout the textile fibers.

Giving Consumers a Convincing 'See, Feel, Wear' Experience

Wang Yeh-hsun believes that consumers immediately see the difference in innovative, improved textiles containing oyster shell, and readily choose these eco-friendly products. 
According to Wang Yeh-hsun: "Careful control of the processing temperature and milling permanently eliminates the oyster shell's unpleasant odor. Our oyster-shell textiles are warm and quick-drying, emit warming far infrared, and repel insects. As a result, these products offer multiple benefits and great value for the money."
To boost consumer confidence, Creative Tech has collaborated with ITRI to enhance its products and has obtained multiple third-party certifications that attest to their quality. Notably, Creative Tech's products received Bluesign certification in 2016, providing consumers with a strong assurance of quality.

To ensure that both consumers and vendors recognize the numerous benefits of its oyster-shell textiles, Creative Tech has actively participated in various trade shows and promotional activities. "The introduction of sustainable products must begin at the design stage, and we aim for our products to offer consumers an appealing 'see, feel, wear' experience," said Wang Yeh-hsun. At these trade shows, foreign vendors often express curiosity about the oyster-shell textiles, typically asking three questions: How did you come up with this idea? What are the benefits of oyster shells? How does using oyster shells contribute to environmental sustainability? When they hear Wang Yeh-hsun's explanations, they are consistently amazed by this innovative eco-friendly material.

Chairman Wang firmly believes that sustainability, combined with an enhanced consumer experience, makes oyster-shell textile clothing an ideal choice for everyday use:  "These textiles are a win for society, for our company, and for consumers."
Our Seawool and Seawarm textiles have garnered prestigious IF and Red Dot international design awards. Additionally, we have developed the "Hulk Bio-Ceramic" material and collaborated with building material vendors to create our Ocean Floor sustainable, germicidal flooring.

Looking to the future, we will continue to partner with others to expand the application of oyster shells into even more everyday product categories. We envision a time when oyster shells will be incorporated into a wide range of daily-use items. By integrating oyster shells into textiles, building materials, and even residential products, we are offering consumers a variety of enticing new choices and experiences.
