The deinkability of conventionally printed products depends largely on the printing technology and on the type of ink applied on the paper substrate, but sometimes also the paper itself (coated or uncoated), and the age of the printed product at the time of deinking. The Deinkability Score assessment defines categories of printed products with different target values…

The deinkability assessment according to EPRC (European Paper Recycling Council) sets targets and limits for the evaluation of the deinkability of a print product and is based on the results of INGEDE Method 11.1 In total, five parameters have to be determined for the assessment of the deinkability (Figure 1). Three parameters characterise the deinked pulp (DIP) quality. Luminosity Y gives information…

Newspapers and magazines in Europe are mainly based on papers manufactured from mechanical pulp and deinked pulp, so-called wood-containing papers. The most efficient deinking processes for these paper products are in an alkaline environment. Therefore, deinkability tests developed also assume alkaline deinking conditions. INGEDE was the first and only association which established a deinkability standard…

On March 18, the 450,000-ton packaging paper project at Five Continents Specialty Paper Industry Group Co., Ltd.’s Hubei base (hereinafter referred to as ‘ Five Continents Specialty Paper’) was successfully put into production!” The paper machine of this project has a width of 8600mm and a design speed of 1200m/min, and is used to produce…
