Corrugated Line Waste-Edge Recycling & Circulation: Turning Offcuts Back Into Raw Material

Corrugated board production lines generate large amounts of waste edge at trimming and slitting. Piling it up not only takes space but also poses safety hazards. Building a waste-edge recycling and circulation system turns offcuts back into raw material.

Scenario: Three Problems in Waste-Edge Handling

Improper waste-edge handling has three problems:

Pain Points

• Accumulated waste edge takes space, hurting workshop tidiness and safety;
• Directly discarding it wastes raw material and raises purchasing costs;
• Without a recycling system, waste edge value is underused.

Solution: Three Recycling and Circulation Approaches

Corrugated waste-edge recycling has three approaches:

1. Shredding and reuse system. Waste edge is shredded and reused in paper pulping or as filler.

2. Automatic collection and conveying. Waste edge is auto-collected and air-conveyed to collection points, reducing manual handling.

3. Baling and resale. Waste edge is baled and sold to recycling companies for resource utilization.

Result: Lower Cost and Greener

With the recycling system built, waste edge turns waste into value and the workshop stays tidy and safe—both cost-saving and eco-friendly.
