Title:

Terephthalate Esters (Dioctyl Terephthalate) from Virgin and Post-Consumer Polyethylene Terephthalate (PET) Waste Plastic

Value Proposition:
  • One-Pot Catalytic degradative transesterification process
  • Indigenous and Scalable waste plastic depolymerization technology
  • Closed-loop recovery of both solvent and solid acid catalyst,
  • Zero-waste manufacturing eco-system
  • Drop-in replacement product
Summary Application:
  • One-step catalytic degradative transesterification process that converts PET waste plastic into terephthalate esters like dioctyl terephthalate (DOTP)
  • Alternative to phthalate-based plasticizers
Advantages:

Production of Dioctyl Terephthalate (DOTP), a non-phthalate plasticizer used widely in manufacturing PVC-based products.
