NineSigma, representing a global chemical manufacturer (“Client”), seeks a partner in the development of technologies to obtain bis (2-hydroxyethyl) terephthalate (BHET) by the depolymerization of polyester fabrics. Technologies that can be applied to a pure polyester fabric will be considered, but those that can also be applied to polyester fabrics blended with other fibres (e.g., cotton, nylon) or containing dyes/pigments are more desirable.
Polyester fabric used as a raw material: Technologies using a polyester fabric with a purity of 100% are acceptable, but those that can also be applied to polyester fabrics blended. In addition to glycolysis, a wide range of approaches are expected, e.g. methanolysis or other hybrid technologies. However, they must be able to become a continuous process that can theoretically be applied to industrial production.
Submissions to this Challenge must be received by Oct 28, 2020.
