SAYA is the research and development unit of the Nan Ya Plastics company, one of the world’s largest recycled PET manufacturers, repurposing over 75 billion plastic bottles annually. The focus of SAYA is on recycling and sustainability that face the textile and garment industry redefining what’s possible in renewal.
SAYA’s RSCUW technology turns a companies deadstock into recycled fibers for mills to weave into fabrics that carry a high tensile strength for dyeing accuracy and whiteness. SAYA is converting scraps, overruns, and leftover fabric (deadstock) into recycled fibers to pave the way to a greener planet.
The company utilizes deadstock for recycling. In an interview, Mr. S.Y. Huang, Senior Vice President, said that deadstock is the garment industry’s most extensive hidden waste area: overstock fabrics. These are generally referred to as leftover fabrics, accounting for up to 25 percent of a manufacturer’s annual waste. Most overstock fabrics have been downcycled in the past, ending up in landfills or incinerators as there are no commercially effective methods to recycle them.
They create millions of yards of our industry’s unaccountable waste.
We’re committed to finding a solution.
He further added that they offer various technical applications to SAYA 365, our recycled bottle program, and our RSCUW, including protected color (Chromuch solution-dyed fiber), stretch, antibacterial, and microfibers. The recycled fibers’ lifecycle is as long as any new virgin fiber, thanks to our proprietary process of sorting and cleaning and mechanically and chemically recycling.
As for helping the environment, our studies show that SAYA fiber compared to virgin fiber, can save around 68 percent to 77 percent of the CO2 produced in manufacturing a garment. We’ve solved one of the most critical sustainability issues in the textile industry and want to redefine what’s possible in renewal. And consumers want to support brands with similar values.
