TOKYO – Japanese technology and fibres firm Teijin says it has developed a solution capable of chemically recycling coloured polyester back into virgin quality fibres. Teijin Frontier, the Teijin Group’s fibres and products converting company, says it made the breakthrough by using a new depolymerisation catalyst.
It claims the technology produces recycled materials equivalent to virgin raw polyester, and also reduces energy consumption while reusing wastewater and depolymerisation catalysts.
