The fuel nozzle drip retainer is a simple yet innovative way of saving millions of litres of fuel on a global scale. Anyone who has pumped fuel before has noticed the drops that fall to the ground after you’ve removed the nozzle from the vehicle. We’ve designed a method of retaining these drops, which initiates a recycling process whereby the next customer in line receives the fuel that would have been otherwise wasted. These drops may not seem like a significant amount, however when taken into account globally, these drops amount to approximately half a billion litres of fuel that falls to the ground and is evaporated into our atmosphere every year. Our drip retainer mesh design utilizes a combination of pressure differentials and surface tension to retain fuel within the spout.
