Enzymatic Recycling
Enzymatic Chemical Recycling Process
Pre-treatment
Post-consumer polyester textiles are sorted, shredded and pretreated into particles suitable for enzymatic depolymerization.
Depolymerization
Enzymatic solution is added in aqueous phase for depolymerization, with both enzymes and water can be recovered and recycled for reuse.
Purification
High-purity intermediates are obtained through filtration, ultrafiltration, decolorization, crystallization, centrifugation, drying and rectification.
Polymerization
Recycled monomers are repolymerized into t2t trPET chips for dope-dyed yarns and subsequent textile production.
Technology Advantages
Suxin Enzymatic Technology Advantages
Low-impact Conditions
Low Temperature, Atmospheric Pressure, Aqueous System
Compared with traditional high-temperature, high-pressure or solvent-based chemical recycling processes, the enzymatic process reduces energy consumption and system stress, ideal for low-carbon, compliant applications and complex textile waste treatment.
