Cruise Ship Food Waste Cost & Digester ROI Calculator
Estimate cruise food-waste generation, digester capacity, landed-waste reduction, utility and labor effects, annual operating value and lifecycle ROI. Advanced mode separates passenger, crew and galley waste, port-disposal routing, power source, cold-storage relief and full retrofit CAPEX.

Model Boundaries & MARPOL Routing NoteUse as a planning screen, not a discharge-permission determination
Mass balance: generated food waste is routed to the digester up to available annual capacity. Processed mass is reduced by the entered treatment percentage; unprocessed food waste and residue then follow the entered landed-disposal shares.
Regulatory boundary: the tool does not determine discharge eligibility. MARPOL Annex V generally prohibits garbage discharge except specified categories/conditions. Food-waste rules depend on whether waste is comminuted/ground, distance from land, special-area/Arctic-water status and other conditions. Enter the landed share that applies to the vessel's actual garbage-management plan and itinerary.
Economics: Advanced compares digester electrical demand with avoided cold-storage load, values onboard electricity using generator SFOC/fuel price and shore electricity using the entered tariff, then adds disposal, labor, optional carbon value and lifecycle costs.
