The European Green Pact launched a concerted strategy for a "circular", climate-neutral, resource-efficient, and resource-efficient economy. Yet globally, only about 20% of textiles are collected separately from the rest of the waste, with a truckload of textiles sent to incineration or landfill every second, and less than 1% of all textiles in the world are recycled into new textiles. In this context, the environmental impact (air, soil, water) due to the landfilling of these textile wastes is huge. In this regar...
