The Diaper Recycling Machine is a fully automated, industrial-grade separation system specifically engineered to process defective, expired, and offcut disposable hygiene products.
Through an integrated workflow of shredding → fiber opening → multi-stage screening → pneumatic classification → dust collection , this Diaper Recycling Machine cleanly separates each component of a diaper into three high-purity output streams: PE/PP plastic composite (non-woven + backsheet film) , fluff pulp (wood cellulose fibers) , and SAP (Super Absorbent Polymer granules) .
The standard Diaper Recycling Machine configuration delivers a processing capacity of 300–500 kg/h (6–8 metric tons per day) , with upgraded high-capacity Diaper Recycling Machine models available for 800–1200 kg/h throughput.
This Diaper Recycling Machine is widely deployed by diaper manufacturers, sanitary napkin converters, waste management companies, and industrial recyclers across Asia, Europe, Africa, and the Americas to recover valuable raw materials, reduce landfill dependency, eliminate incineration costs, and create a profitable closed-loop recycling revenue stream.
Compatible Raw Materials for the Diaper Recycling Machine
- Expired / Near-Expiry Finished Products
- The Diaper Recycling Machine efficiently processes nearly expired baby diapers, adult incontinence pads, sanitary napkins, panty liners, breast pads, and pet training pads that are unsuitable for sale but contain fully usable internal materials.
- Production Defects & Rejects
- Non-conforming diapers rejected during inline QC — including misaligned cores, defective elastic bands, faulty adhesive tapes, weight variation, cosmetic blemishes, and packaging errors — are ideal feedstock for the Diaper Recycling Machine.
- Manufacturing Trim & Offcuts
- Edge trimmings, guillotine cuts, matrix waste, roll ends, and leftover webs generated during converting operations. The Diaper Recycling Machine recovers these materials which otherwise account for 3–8% of typical diaper production output losses.
- Broader Absorbent Hygiene Products (AHP)
- The Diaper Recycling Machine also handles adult diapers, nursing pads, wound dressings, disposable bed mats, pet pee pads, and any laminate combining non-woven fabric, PE film, fluff pulp, and SAP.
Working Principle & Process Flow of the Diaper Recycling Machine
- Feeding & Coarse Shredding. Operators load waste diapers into the machine’s hopper. Hardened steel rotary shredders cut diapers into 3–8 cm fragments, breaking layered structures and exposing inner absorbent core materials.
- Fiber Opening & Defibration. Shredded materials flow into the fiber opening chamber. Pin-rotor beaters and air flow separate non-woven layers, untangle fluff pulp, and release intact SAP granules without damaging polymer structures.
- SAP Screening & Classification. Materials pass through a multi-layer linear vibrating screen with precise stainless steel mesh. Adjusted vibration and tilt separate dense SAP granules through the mesh, leaving pulp and plastic to move onward, delivering over 95% pure SAP.
- Plastic & Pulp Air Separation. Mixed plastic and pulp enter the air classification unit. Regulated airflow lifts lightweight pulp fibers into cyclone collectors, while heavy PE/PP plastic sheets drop to an exclusive discharge screw.
- Dust Collection & Closed-Loop Conveying. Built-in two-stage cyclone equipment with bag filters traps floating fiber dust, recycles recoverable pulp back into production, and keeps workshop dust within safe standards.
- Sequenced Separate Discharge. The machine outputs three independent clean recyclable materials via dedicated outlets:
- Outlet A: PE/PP plastic composites for plastic granulation.
- Outlet B: Purified fluff pulp for secondary processing.
- Outlet C: High-purity recycled SAP for low-grade absorbent products.
