Meet MARPOL Waste Disposal Requirements

JWC’s MARPOL food waste shredder, which is certified by the American Bureau of Shipping (ABS), supports meeting MARPOL Annex V food waste disposal requirements.

The International Maritime Organization (IMO) has recently strengthened its MARPOL Annex V Resolution around food waste disposal. Food waste must be ground to 1″ (25mm) chunks or smaller before disposal. The ground food waste can be discharged if the ship is three nautical miles or more from land and outside of defined “special areas” or 12 nautical miles or more from land if you are in a special area.  The Monster Industrial MARPOL food waste shredder is certified by the American Bureau of Shipping (ABS) and can help ships meet these updated requirements.

JWC has helped numerous marine operators stay in compliance with its Monster Industrial SHRED grinders. JWC’s grinders have received multiple certifications from the American Bureau of Shipping (ABS) including a product TYPE Approval and a certification of compliance for meeting MARPOL Annex V. This aids designers in specifying JWC SHRED products and gives operators confidence in their compliance to the regulations.

MARPOL Food Waste Shredder

The Monster Industrial 1, 3 and 4-SHRED grinders are the most powerful solution available for ship-based food waste disposal. Two shafts of sharp steel cutters use slow-speed, high-torque power to slice through mountains of tough food waste including t-bone steaks, ribs, whole chickens and even the occasional spoon or plate. It is also available in a packaged solution with the hopper, grinder, control panel and discharge tubing all designed and built by JWCE to fit inside a compact corner onboard the vessel.

Marine Sewage System Grinders

Multiple international laws and regulations help protect global waterways from waste. In addition to food waste, operators of river and ocean-going vessels, along with offshore platforms, must take care to manage crew sewage. Monster Industrial grinders work on ships and platforms to keep marine sewage systems flowing and compliant. Monster Industrial grinders stop sewage backups and pipeline clogs!

Monster Industrial marine sewage system grinders keep your onboard wastewater system flowing freely. They grind up all kinds of debris into small particles, minimizing solids backups that require clean out. This not only reduces maintenance costs but also protects the health of the crew.  1-HYDRO & 3-HYDRO grinders protect pumps from rags, hygiene products and other items that should not be flushed in the first place.

Oil Spill Cleanup

Oil Spill Cleanup

Oil skimming boats collect more than just oil and water – seaweed and trash can clog pipelines and valves on the ship, shutting down pumping operations.  Monster Industrial shredders like the 3 & 4-HYDRO can keep valves, pumps and pipelines clear of debris so the important works of clean up can continue without interruption.
