  • Publication number: 20240101883
    Abstract: The described aspects relate to a dust suppression resin, and a method of obtaining the dust suppression resin through the chemical recycling of thermoplastic polymer Poly(Ethylene Terephthalate) or PET. The method for obtaining the resin includes a depolymerization reaction applied to the Poly(Ethylene Terephthalate) polymer, such as post-consumer PET fragments, in the presence of the quaternary ammonium cationic surfactant. The method further includes subsequently adding a hydrophilic substance to increase a final viscosity of the resin. Other additives such as lignin extracted from vegetables, such as leaves and branches of trees, can also be added to make the resin more hydrophobic.
