Superhydrophobic PP sheets of varying thickness having a base layer and a top layer may be fabricated using recycled or waste PP, where the fabrication process uses 20% of total plastic waste to prepare said sheets having contact angles ranging from 140 to 160 degrees. The polypropylene (PP) superhydrophobic sheets may impart protective water-repellent properties against the elements.
