Deployment of a High-Capacity Corrugated Container Recycling Line

Minhan Paper and ANDRITZ are cooperating to deploy a complete old corrugated containers recycling line in Hung Yen province, Vietnam. This technical integration focuses on the packaging paper sector, specifically targeting the efficient production of high-quality corrugating medium from recovered materials.

Target Applications and Industry Context
The system serves the industrial packaging and paperboard manufacturing industry. Specifically, it processes recovered materials to produce testliner and corrugating medium. The implementation addresses the operational challenge of maximizing fiber recovery while maintaining process stability and minimizing raw material waste during continuous, high-volume production.

Cooperative Roles and Technical Integration
The partnership addresses the technical requirements of sustainable recycled fiber processing. Minhan Paper provides the operational infrastructure, site logistics, and production framework within the containerboard market, while ANDRITZ supplies the industrial automation and mechanical process technology. This cooperation facilitates the complex integration of a comprehensive mechanical and fluid handling architecture into the existing mill infrastructure, ensuring compatibility with the facility's previous technical deployments.

System Architecture and Processing Technology
The deployed process covers all physical stages from initial pulping to final refining. The system utilizes low-consistency pulping technology to initiate fiber separation. Subsequent processing stages include multi-stage screening, centrifugal cleaning, and reject dewatering to systematically isolate and remove impurities from the fiber suspension.

The technical architecture also incorporates a paper machine approach flow system, a dedicated broke handling unit, and a disc filter saveall system engineered for white water treatment. These synchronized modules function to maintain high impurity-removal efficiency, stabilize the overall fluid flow, and minimize physical fiber loss throughout the processing cycle.

Deployment Phases and Operational Output
The mechanical components and control systems will be implemented at the Hung Yen facility, with the operational start-up scheduled for the first half of 2027. This project constitutes the second deployment of this specific recycling architecture at the site.

Once fully integrated and operational, the primary production line is engineered to operate with a capacity of 700 tons per day. Concurrently, the integrated broke handling system is scaled to process an additional capacity of 100 tons per day. These specified parameters establish a measurable increase in overall resource utilization and daily production throughput for the facility.
