Materials Processed
Woven Bag Feedstocks We Process
From cement and fertilizer sacks to FIBC jumbo bags, rice bags, raffia and mixed PE/PP streams.
FIBC / Jumbo Bags
Heavier-gauge PP ton bags (500–2,000 kg) usually cleaner, best handled by a twin-shaft shredder.
Fertilizer & Chemical Sacks
Hot washing removes water-soluble chemicals; sink-float separation gives a separate mineral contaminant stream.
Rice, Grain & Agricultural Bags
The cleanest source — water-soluble residues wash off even at ambient temperature, ideal for 300–500 kg/h entry lines.
Raffia Bags & PP Tape Products
Woven PP raffia yarn products; washing lines segregate mixed colors for premium pale-colored pellets.
PE Film & Soft Plastic Co-Processing
Mixed bales of woven bags and LDPE/HDPE film can be processed together, adjusting operating parameters between material types.

Machine modules
The equipment behind the washing route.
Core modules for feeding, crushing, washing, separation, dewatering and line control.
01
Belt Conveyors & Screw Loaders
Variable-speed conveyors and screw loaders connect the washing stages and maintain a steady material feed.
02
Wet Crusher
Water-assisted crushing reduces woven bags to a consistent size while releasing loose dirt and residues.
03
High-Speed Friction Washer
Mechanical scrubbing removes soil, labels and persistent contamination from the woven fabric.
04
Sink-Float Washing Tank
PP woven material floats while heavier contaminants settle and are discharged from the washing tank.
05
Squeezing & Dewatering Unit
Mechanical squeezing removes most free water from washed woven flakes before drying or pelletizing.
06
PLC Control Cabinet
Centralized controls coordinate material feeding, motors and the complete washing sequence.
FAQ
Frequently Asked Questions
Answers to the questions woven bag recyclers ask most.
Can a PP woven bag washing line handle heavily contaminated waste like cement bags or fertilizer sacks?
Yes. A dedicated hot washing tank operates at 60–80°C to dissolve cement powder, fertilizer chemicals and melted label adhesive. Dual-stage friction washing and sink-float separation bring flake purity above 95%.
How do I choose the right capacity for my PP woven bag recycling project?
Start with your daily feedstock. A 300–500 kg/h line suits 3–5 tons/day of collection, while 1,000–1,500 kg/h handles municipal or industrial waste of 10–20 tons/day. Consider floor space and whether you will sell washed flakes or finished pellets.
Why is recycling FIBC bulk bags and jumbo bags worth the investment?
FIBC and jumbo bags are made from high-quality virgin or near-virgin polypropylene. With PP priced at $800–1,200 per ton, recycled flakes and pellets from these feedstocks command premium resale prices.
What output quality can I expect from recycled PP flakes?
Moisture content is usually below 5% after squeezing and down to 1.5% after thermal drying, with flake purity above 95% from FIBC and cement bag feedstock. With a pelletizing line, the pellets suit most PP applications including injection molding and tape extrusion.
How do you recycle polypropylene woven bags step by step?
Nine stages: bale breaking and conveyor feeding, shredding/crushing, pre-wash and label removal, high-speed friction washing, sink-float separation, secondary friction washing, centrifugal dewatering, hot air drying, and optional pelletizing with degassing.
Can cement bags be recycled into pellets for reuse?
Yes. A hot wash at 60–80°C lets calcium-based cement re-dissolve, and friction washing cleans residual particles off the PP tape. The washed flakes can be pelletized for injection molding of non-food goods, flower pots or woven bag tape extrusion.
What is the energy consumption of a PP woven bag recycling machine?
Installed power of a 500 kg/h washing line without pelletizing is 120–180 kW, or about 0.25–0.35 kWh/kg at rated conditions. Adding pelletizing increases installed power by 80–150 kW. PLC control with variable-frequency drives reduces power consumption by 15–25% at partial loads.
