RECYCLING A SUPERABSORBENT POLYMER USING HYDROTHERMAL TREATMENT
Poly(acrylic acid)-based superabsorbent polymer (SAP) in a feed stream is converted into poly(acrylic acid) (PAA) in a hydrothermal treatment (HTT) reactor. The total energy used to degrade the SAP into PAA is less than about 50 MJ/kg SAP.
