PUFF (Polyurethane Foam Flex) is a first-response solution for oil spill clean-up operations developed by Italian company TEST-1 S.r.l as. PUFF is a patented oleophilic, hydrophobic open-cell flexible polyurethane foam used to absorb oil from water. The PUFF wringing machinery is shown below.
PUFF can absorb 23 times its own weight in hydrocarbons, including 10w40 oil, light and heavy fuel oils and crude oils.
PUFF can be reused up to 100 times.
Once PUFF absorbs oil, it is wrung out using machinery engineered and built by TEST-1, which allows recovery of the adsorbed oils uncontaminated by water.
Tests show that PUFF’s rate of absorption is higher when waves are present which allows its use in adverse weather conditions where most clean-up methods are ineffective.
PUFF’s overall cost is three to eight times lower than that of adsorbents currently available on the market. Finally, reuse means up to a 10-fold decrease in the product to be disposed of after use.
