  1. End of Life Cycle and Recycling
    Repair in case of local damage
Reuse – donation or second-hand
Recycling: the material can be processed into insulation or filling products (downcycling), while full recycling back into textiles of the same type is not practically available today
Advanced chemical or enzymatic separation technologies exist in a pilot phase but are not commonly available at a large scale
