avskumming

Avskumming, also known as deinking, is a process used to separate paper fibers from ink and other contaminants in recycled paper. This process is crucial for producing high-quality recycled paper products. The primary goal of avskumming is to remove ink and other contaminants to ensure that the recycled paper meets the required standards for reuse.

The process typically involves several steps. First, the used paper is shredded into small pieces. These pieces are then mixed with water and chemicals to break down the ink and other contaminants. The mixture is passed through a series of screens and flotation tanks, where the ink and other contaminants float to the surface and are removed. The remaining fibers are then washed and dried to produce clean, recycled paper.

Avskumming is essential for the paper recycling industry as it allows for the efficient reuse of paper fibers, reducing the need for virgin paper and minimizing waste. The quality of the recycled paper produced through avskumming depends on the effectiveness of the process in removing contaminants. Advances in technology and chemical treatments have improved the efficiency and quality of avskumming, making recycled paper a more viable and sustainable alternative to virgin paper.
