Protecting global waterways from waste is governed by multiple international laws and regulations. Operators of river and ocean going vessels along with offshore platform application must take care to manage multiple types of waste including the crew sewage and food waste. Monster Industrial grinders work on ships and platform to keep the marine sewage system in compliance and waste flowing. Monster Industrial grinders stop sewage backups and pipeline clogs! Our MARPOL food waste shredder, which is certified by the American Bureau of Shipping (ABS) supports meeting MARPOL Annex V food waste disposal requirements.


Monster Industrial marine sewage system grinders are used to 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 will protect pumps from rags, hygiene products and other items that should not be flushed in the first place.


Oil skimming boats collect more than just oil and water – seaweed and trash can clog pipelines and valves onboard 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.


The International Maritime Organization (IMO) has recently strengthened its MARPOL Annex V Resolution around food waste disposal. Food waste must be ground down to 1″ (25mm) chunks or smaller before disposal. The ground food waste can be discharged if the ship is 3 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) for its products include a product TYPE Approval and a certification of compliance for meeting MARPOL Annex V. This aids designers in specifying JWC SHRED products and give operators confidence in their compliance to the regulations.

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 on-board the vessel.
