Why RPET and not cotton?
Current worldwide demand for textile fibers is over 100 million tonnes per year and synthetic fabrics account for more than 50% of this consumption. Trying to replace synthetic fibers with cotton would have an immense environmental impact.
Natural fibers like cotton, when compared with synthetic fibers, present advantages in terms of waste production due to the biodegradability of both their discarded textiles and their micro-fibers. However, cotton has a very intensive resource consumption, mainly in terms of water and land degradation, due to the use of insecticides and herbicides. The cultivation and production of 1 kg of cotton requires on average 20,000 liters of water and some experts indicate that cotton is the largest user of water among all the agricultural commodities.
RPET fabric has a 50% lower carbon footprint than organic cotton. Furthermore, compared with other synthetic fibres, RPET polyester fabric has almost a 90% lower carbon footprint than nylon, and 75% lower than polyester
