The transition to a circular economy requires that much of the material that today is regarded as waste is utilized as a material resource. In this project, we focus on investigating the chemical content of textile materials for material recycling based on fiber type as well as product type.
For efficient use of the material resource that textiles for material recycling constitute, it is of the utmost importance to have control over the composition of the material. This regarding fiber composition, as well as chemical content.
In a circular economy, non-toxic textile raw material is a prerequisite. Thus, recycled textile fiber must be below the applicable limit values for chemical content. Content of harmful substances above the tolerance limit can, depending on recycling technology, place restrictions on the application of recycled material and it is therefore of utmost importance that this is under control prior to processing and utilization. Chemical content can also affect chemical processes, for example in various types of chemical recycling, pointing to the fact that information regarding chemical content is of great importance also for these recycling technologies.
This project aims at increasing knowledge of the current situation in regard to chemical content in textiles for material recycling. The project also focuses on developing a tool, or a model, for categorization / classification of textile materials intended for material recycling. This specifically regarding risk assessment based on chemical content and the possible restrictions this places on the possible applications for recycled textile material. The categorization of textile material is linked to a number of different analysis packages for assessment of textile material.
