Classification and risk assessment of textile for material recycling

Purpose and goal

** Denna text är maskinöversatt ** This project has aimed to significantly increase the level of knowledge regarding chemical content in textiles for material recycling. The material that formed the basis for the analyzes performed is post consumer textile collected via charities that for the project have been sorted based on type of fiber as well as product category. This since the product type has significant impact on possible content of hazardous chemicals. The intention of the project has also been to establish recommendations regarding chemical analysis for specific fractions.

Expected results and effects

** Denna text är maskinöversatt ** Of the factions analyzed, the majority is compliant with the requirements for OEKO-TEX certification. No category contained chemical levels above applicable legal requirements. This makes it much more difficult to put together a recommendation regarding chemical analysis for recycled fractions, since a given indicator chemical is missing. A discussion of this is conducted in the user guide, which also includes a recommendation, and indicates important parameters to consider when sorting for material recycling.

Planned approach and implementation

** Denna text är maskinöversatt ** Textile material was collected via Innovatum and the Wargön Innovation project, which also sorted all material by fiber type and product type according to RISE´s specification and in dialogue with project partners. A method for sample preparation and analysis was developed, validated and used. Analyzes were conducted in two large blocks with evaluation and discussion in between. Discussion about sorting and possible classification / categorization was performed continuously. Classification and standardization around this is the next step.
