How to Deink Used Newspaper

After recycling, old newspaper often retains a large amount of ink and other impurities, which affect the quality and color of the recycled paper. Therefore, deinking not only improves the purity of the paper and enhances the market competitiveness of recycled paper, but also contributes to environmental protection.

Common Deinking Methods

1. Chemical Deinking: Using chemical agents to separate ink from paper fibers. While this method is highly efficient, it may cause secondary pollution.
2. Physical Deinking: This method removes most ink through mechanical force, commonly using methods such as friction and grinding. Physical methods are environmentally friendly, but their effectiveness is limited for certain inks.
3. Flotation Deinking: Flotation is a widely used deinking technology in the industry. It separates ink particles from pulp using air bubbles, offering advantages such as high efficiency, environmental friendliness, and ease of operation.
