Firstly, small projects like this are just a drop in the ocean compared to the amount of waste plastic, from clothes and packaging, polluting nature each day. Using littered bottles to make clothing does nothing to stop this, and the bottles need to be prevented from reaching the oceans in the first place.

Secondly, turning bottles into clothing is a false solution, because once turned into fibre it cannot be recycled futher and instead must be landfilled or incinerated at the end of life, whereas if it remains a bottle it can be recycled or reused a number of times. In fact, because of this, in Europe more PET plastic pollution comes from textiles than from bottles.
