Paper recycling<\/h3>\n\n\n\n

What actually happens when paper is recycled? It\u2019s all about what\u2019s called \u201cpulp.\u201d This refers to a pulpy mass of various fibrous materials, namely wood pulp, which consists of varying proportions of cellulose, hemicellulose and lignin, normally along with waste paper.<\/p>\n\n\n

Waste paper is usually the most important raw material for paper in terms of quantity, at least in the case of recycled paper. Waste paper gets broken down into its individual fibers using water in the pulper. The secondary waste paper fiber obtained in this way is then available for the production of new paper.<\/p>\n\n\n\n

However, there is the question as to whether the adhesive contained in the waste paper \u2013 e.g. from labels \u2013 affects the quality of the recycled paper. artimeltrepulpable<\/strong> is a hot-melt adhesive that says: it shouldn\u2019t. Initial tests prove this.<\/p>\n\n\n\n

Best in Class<\/h3>\n\n\n\n

During repulping, it is important that the filtration processes involved remove as many substances as possible from the pulp that should not be part of the new paper: ink, plastic components and adhesives, too. Tests have shown that when artimeltrepulpable<\/strong> is used, all adhesive residues and the paper fibers adhering to them can be filtered out. The \u201cRejectScore\u201d was an outstanding 93 out of 100 points (at 2.7% coarse reject + 0.7% fine reject) \u2013 which corresponds to a \u201cbest in class\u201d rating! In addition, the pulp retains a large portion of its fibers during the recycling process when artimeltrepulpable<\/strong> is used, meaning fiber loss remains low and paper yields high.<\/p>\n\n\n\n

Further aspects<\/h3>\n\n\n\n

When recycling paper, it is also important to consider whether the recycled paper contains any impurities and how high the sheet adhesion is. In order to have material on hand to check for these, test sheets are pressed from the newly extracted pulp.<\/p>\n\n\n\n

In the case of artimeltrepulpable<\/strong>, the visible impurities were classified as \u201cacceptable\u201d for production. However, these impurities could not be clearly attributed to the adhesive present in the starting material. They may simply come from the waste paper sample used.<\/p>\n\n\n\n

\u201cSheet adhesion\u201d refers to the degree of adhesion between individual sheets of paper. Of course, it shouldn\u2019t be too high, as otherwise a printer, for example, will draw in several sheets at once. The test sheets allow us to measure the subsequent sheet adhesion, which is divided into three levels. And here, too, the results for artimeltrepulpable<\/strong> are extremely encouraging, as the sheets reached Level 1, i.e. \u201cno adhesion issues\u201d (Level 2 = minor adhesion issues, Level 3 = significant adhesion issues).<\/p>\n\n\n\n

Summary<\/h3>\n\n\n\n

Overall, the product artimelt L1 945, which has now been presented as the first representative of the artimeltrepulpable<\/strong>\u00a0family, performed excellently in the tests. The overall result was a score of 88 \u2013 significantly more than sufficient to enable paper recycling (scores between 0 and 100 are considered \u201csuitable for standard mill recycling\u201d). For the paper and cardboard industry, this means that products manufactured with these hot melts can be easily recycled. The pulp produced during the recycling process is free of adhesive residues and is therefore suitable for higher-quality paper and cardboard products.<\/p>\n\n\n

Applications<\/h3>\n\n\n\n

In addition to the paper and cardboard industry, artimeltrepulpable<\/strong> is likely to be of great help in the production of packaging materials in general, as well as in the labeling of paper products. This also applies to bonding cardboard boxes. If they are intended to be recycled, adhesive residues interfere with the process. artimeltrepulpable<\/strong> solves these problems. The new products are clean, high-quality and environmentally friendly.<\/p>\n\n\n\n

Sustainability at artimelt<\/h3>\n\n\n\n

Beyond the specific adhesive series with the artimeltrepulpable<\/strong> property, our efforts in service of sustainable product development encompass a large number of other aspects. They range from the selection of raw materials and the actual production to the application phase and the question of what happens to a product at the end of its life cycle, because the issue of recycling also affects the adhesives industry.<\/p>\n\n\n\n

However, since suppliers such as artimelt have no control over the actual application phase of their products, the system boundary of the life cycle assessment (LCA) must be narrowly drawn: the \u201ccradle-to-gate\u201d approach assesses the environmental impact of a product from when the raw materials are extracted up to the point of reaching the factory gate. CO2<\/sub> equivalents (into which other greenhouse gases are also converted) are the key unit of measurement, and the most commonly used metric for this kind of assessment is the product carbon footprint (PCF).<\/p>\n\n\n\n

An example of lasting impact despite limited system boundaries is the artimeltrepulpable<\/strong> product line. Improved paper recyclability extends the use cycles of the end products, thus reducing the overall environmental impact \u2013 which in turn has a positive impact on the end product\u2019s PCF.<\/p>\n\n\n

Initial PCF values are already available for selected products. On request, artimelt also calculates the ecological footprint of customer-specific hot melt adhesives.<\/a><\/p>\n\n\n\n
