First, the collection efforts associated with these yarns divert these plastic bottles from ending up in landfill (or other harmful places like our oceans).
Second, this process of converting PET into recycled polyester requires much less energy than in the case of normal polyester.
Third, using more recycled polyester reduces our dependence on petroleum as the raw material for our fabric needs.
Also, another benefit is that the garments created from recycled polyester can be recycled again and again with no degredation of quality, allowing us to minimize wastage.
