Every year tons of yarns and km of fabric are produced in the world. This is an enormous quantity of products and has a significant impact on the environment, both in the production phase and the waste disposal phase. There are many possible approaches to protecting the planet. At 3C Filati, the priority is to intervene regarding what has already been produced, to recycle it and create new yarns. This process contributes to limiting the environmental costs of textile production in terms of water and energy consumption, and CO2 emissions.
