löstmittelgetrennten

Löstmittelgetrennte, also solvent-separated, refers to a process in the production of paper where the fibers are separated using a solvent rather than water. This method is particularly useful for recycling certain types of paper waste, such as newsprint and magazine paper, which are often contaminated with inks and other substances that can interfere with the traditional water-based pulping process.

In the solvent-separated process, the paper waste is first shredded into small pieces. These pieces are then treated with a solvent, typically a mixture of organic chemicals, which dissolves the contaminants and separates the fibers. The solvent is then evaporated, leaving behind the clean fibers. These fibers can then be used to produce new paper products.

The solvent-separated process has several advantages over traditional water-based pulping. It can handle paper waste that is difficult to recycle using water-based methods, and it can produce fibers that are of a higher quality. However, it also has some disadvantages. The solvents used in the process can be expensive and environmentally harmful, and the process itself can be more energy-intensive than water-based pulping.

In recent years, there has been a growing interest in the solvent-separated process as a way to increase the amount of paper waste that can be recycled. However, the technology is still in its early stages of development, and there are many challenges that need to be overcome before it can be widely adopted.
