Greypen's Slicker Solution

Each month Slicker Recycling provide a comprehensive MARPOL service for several vessels under Graypen Port Agency, at the Humber ports, removing the hazardous bilge water and sludge. Due to the nature of the business, Slicker’s team remain at the ready to provide a reliable and reactive service, ensuring there are no delays.

Once collected, the waste product is taken to Slicker’s state-of-the-art facility in Hull, where it is processed and recycled into a high-quality, carbon-efficient, industrial heating fuel. The recycled fuel is then used in industrial applications, such as boilers or kilns, minimising customers’ need to use virgin product, and reducing potential carbon output.

Thanks to their partnership, Graypen have found a reliable and sustainable solution for vessels with maritime hazardous waste under their Port Agency.  But don’t just take our word for it! Rob Wilford, Humber Agency Manager at Graypen Ltd has commented:

“We have been working with [Slicker Recycling] for many years and they provide an outstanding service every time. Our account manager, Sarah, provides expert advice, and their friendly front-line operatives go above and beyond, ensuring our needs are met and the job is completed promptly. As one of the UK’s market-leading tanker agencies, we value their quick and reliable service, meaning minimal disruption to our day-to-day operations. I would highly recommend.”
