Polypropylene (PP) rope is very popular in marine use because it floats, is cheap to produce and is relatively strong and rot resistant. Not the strongest of rope, it is also sensitive to UV degradation that means it can become brittle and weak if left out in the sun. On the foreshore around the Hastings Stade I was able to gather a range of frayed and vary coloured threads.
However, this well managed area is encouragingly largely free of such detritus and my collection took a few hours to gather. I am making it into an ironic sort of Hastings Egglet that acts as a reminder of wider issues around plastic contamination of the seas.
