PU-FF’s performance was compared with that of polypropylene (PP), the adsorbent normally used. PP’s performances were found to be inferior to those of PU-FF in terms of both adsorption capacity and the potential reuse of the material after wringing-out in the case of diesel fuel and crude oil, with 1 cm of oil. In terms of crude oil surface iridescence, PU-FF shows poorer performance compared to PP, as it appears incapable of removing the small amount of crude oil present in a satisfactory manner. This finding was not repeated in the case of diesel fuel, which is completely removed from the surface of the water. The price comparison between the innovative Test 1 material and its current competitor technologies indicates an overall cost of use for PU-FF that is three to eight times lower than that of the absorbents currently available on the market. The main advantages of this material compared to current adsorbents is related to its greater adsorbing capacity, the ability to reuse it after wringing (up to 100 times), and the recovery of the unchanged product, therefore a significant reduction in the amount of product to be disposed of. Quantities for disposal are reduced at least 10-fold, and above all product from the spill can be reused. Its ease of use and capacity to absorb large quantities of hydrocarbons in a short time make PU-FF a potential fundamental primary tool for environmental protection in oil spills.
