This report is the primary outcome from Part I of the project “Towards a Nordic textile strategy - Collection, sorting, reuse and recycling of textiles” initiated by the Nordic Waste Group (NAG). The report for Part 2 will be published in December 2014. This report summarizes the work carried out in 2013. The three subreports will be the basis for the work to be performed in 2014. The reports for 2013 are: • International market survey of textile flows in the Nordic region and the market for collection, sorting, preparing for reuse, reselling and waste management of textiles. • Collection and sorting systems A total of 19 collection systems are compared for collection flows, contamination levels, cost, suitability of collected textile and availability for the consumer. Four sorting systems are described. • Technology review of sorting and recycling of textiles that describes available and future technology. The report is part of the Nordic Prime Ministers’ overall green growth initiative: “The Nordic Region – leading in green growth.” Read more in the web magazine “Green Growth the Nordic Way” at www.norden.org/greengrowth.

Global population growth and rising living standards are increasing apparel consumption. Consequently, consumption of resources and generation of textile waste are increasing. According to the Swedish Environmental Protection Agency, textile consumption increased by 40% between the years 2000 and 2009 in Sweden. Given that there is currently no textile recycling plant in Sweden, the aim of this article is to explore the potential environmental benefits of various textile recycling techniques and thereby direct textile waste management strategies toward more sustainable options. Three different recycling techniques for a model waste consisting of 50% cotton and 50% polyester were identified and a life cycle assessment (LCA) was made to assess the environmental performance of them. The recycling processes are: material reuse of textile waste of adequate quality; separation of cellulose from polyester using N-methylmorpholine-N-oxide as a solvent; and chemical recycling of polyester. These are compared to incineration, representing conventional textile waste treatment in Sweden. The results show that incineration has the highest global warming potential and primary energy usage. The material reuse process exhibits the best performance of the studied systems, with savings of 8 tonnes of carbon dioxide equivalents (CO-eq) and 164 gigajoules (GJ) of primary energy per tonne of textile waste. Sensitivity analyses showed that results are particularly sensitive to the considered yields of the processes and to the choice of replaced products. An integration of these recycling technologies for optimal usage of their different features for treatment of 1 tonne of textile waste shows that 10 tonnes CO-eq and 169 GJ of primary energy could be saved.
