Recycling of waste from the paper industry

Recycling plants for pulper rags and rejects

Waste paper is usually delivered to paper mills in pressed bales held in shape by wires.

The stock preparation process generates rags that comprise wires and other rejects. Rejects are all those materials that are not paper, such as plastics, textiles and metals.

Depending on the requirements, ANDRITZ MeWa plants include several shredding stages in order to break down the stubborn rags properly. The robust machine technology with its very hard wearing cutting gear releases the metals (accounting for up to 40% of the content) completely. Impurities are separated into different fractions by subsequent separation processes. The calorific materials are further processed to provide substitute fuels.
