On this week’s episode, we discuss the production process of a pretty infamous material – polyester, or polyethylene terephthalate (PET) and recycled PET, to be precise. Kim is joined by Sharon Chen, the Director Of Business Development at Baichuan Resources Recycling, a leading manufacturer of recycled textiles in China, who speaks about how virgin and recycled PET are manufactured. Sharon tells us about the types of raw materials needed in the process, who they buy these inputs from, and how they’re processed to ultimately become a yarn. She takes us through the spinning, weaving, and dyeing processes and shares a bit about who their customers are. They also talk about why traceability is so important to the company, and how they approach this.
