Recycled fiber

Customized process solutions with broad know-how and a range of modern technologies for complete lines, rebuilds and process improvements.

Metso’s scope of supply can include engineering, procurement and construction; complemented with the best available technology from selected suppliers to ensure superior performance. Advanced process control from Metso can also maximize process performance to ensure a stable quality furnish to the paper and board production lines. Integrated process controls, quality controls, process sequencing and scheduling control are supported by proven measurements for important process variables and furnish properties.

Deinking solutions
The production of high quality printing papers, newsprint and tissue from recycled fiber is becoming increasingly challenging with the deterioration of collected waste paper from urban communities. Mills today have to handle more furnish variability, as paper qualities get mixed and more contaminated with non fiber materials, yet recover and make full use of all incoming fiber to reduce landfill. Metso’s deinking technology offers innovative and cost-effective subprocesses, from pulping to stock preparation, for efficient impurity removal, high yield, controllable ash content and high brightness gain.

Getting the most from OCC

Producing quality board grades with low quality raw material, such as old corrugated containers (OCC) and mixed waste (MW), places high demands on your recycled fiber processing. The optimization effort begins with specification of the desired properties of the end product. This guides the selection of the stock preparation concept, which must be robust and flexible while meeting the full range of productivity and environmental demands. With Metso, you can optimize the complete OCC line to produce more stable quality pulp while improving efficiency.

Whether you need a full modernization or partial rebuild, OCC systems from Metso facilitate the production of high quality board with good strength properties in a solution uniquely tailored to your needs. The customized process design makes it possible to optimize final pulp quality, process yield, and most importantly, your investment and operating costs.
