Shredded Plastic & Paper
Mixed Recyclables · Refuse-Derived Fuel · Engineered Fuel Feedstock
Shredded plastic and paper is a mixed-material stream generated from recycling, waste processing, and alternative fuel production operations. The material typically consists of shredded paper fibers, cardboard, films, plastic packaging, and other lightweight recyclable components. Its heterogeneous composition creates handling challenges due to varying particle sizes, densities, and flow characteristics. Fibrous paper components can interlock and bridge, while plastic materials may generate static electricity and cling to equipment surfaces. KWS designs specialized conveying systems that provide reliable handling of mixed recyclable materials while minimizing plugging and maintenance.

Material Characteristics
| Property | Value / Description |
|---|---|
| Common Forms | Shredded Paper, Cardboard, Films, Plastic Fragments, Mixed Recyclable Feedstock |
| Bulk Density | 5-20 lb/ft³ (depends on composition, shred size, and compaction) |
| Flow Behavior | Poorly flowing; fibrous and irregular materials tend to bridge and interlock |
| Abrasiveness | Low Contaminants may increase wear |
| Corrosiveness | Not Corrosive |
| Dust Potential | Moderate to High Paper fibers and fines may generate combustible dust |
Handling Challenges
- Bridging and ratholing in hoppers and storage bins
- Material wrapping and plugging in conventional conveying equipment
- Variable feed rates due to inconsistent material composition
- Dust generation and housekeeping requirements
- Static electricity buildup and cling from plastic components
Summary
Shredded plastic and paper require conveying and storage systems designed for lightweight, fibrous, and heterogeneous materials. KWS Manufacturing provides engineered solutions—including shaftless screw conveyors, drag conveyors, and live bottom bins—that ensure reliable material flow while minimizing plugging and maintenance.
With extensive experience handling recyclable materials, alternative fuels, and difficult-to-flow bulk solids, KWS ensures efficient, dependable, and low-maintenance operation for shredded plastic and paper handling systems.
