Abstract
GCI‑V28‑M “Lazarus Prime” v1.2 is a ship‑ or port‑integrated continuous processing system that converts marine biomass and compatible organic wastes into a sanitized, calcium‑rich, biochar‑enhanced fertilizer pellet. The system is organized into three hygienic zones: (1) intake and mastication, (2) hull‑integrated thermal/acoustic processing, and (3) clean dewatering and pelletization. Feedstock blends typically include marine trimmings, cardboard pulp, crushed oyster shell or glass, biochar, and green waste.
After shredding to <10 mm, the material is mixed with seawater to form a 15–20% solids slurry. The slurry passes through a hybrid hydrodynamic/ultrasonic cavitation reactor (three 20 kHz horns, 2 kW total, 316L stainless with ceramic wear inserts) followed by a jacketed plug‑flow reactor (DN100 SS316L, ~280 m effective length). Waste heat from the ship’s engine jacket‑water loop maintains ~70 °C for approximately 52 minutes, achieving a ≥5‑log pathogen reduction consistent with established sanitation time–temperature curves.
A polyurethane‑lined hydrocyclone removes microplastics, and a screw press reduces moisture to ~30%. Steam conditioning activates natural binders before extrusion through a 3.5 mm chromium‑alloy flat‑die pellet mill. Pellets are cooled and dried to ≤10% moisture. Inline NIR spectroscopy provides real‑time moisture and C:N monitoring, while PLC‑based interlocks divert off‑spec material.
Locating the system inside a tanker hull provides acoustic isolation from coastal communities and enables direct seawater intake. The vessel may operate as a stationary offshore platform or travel between ports to collect feedstock. All subsystems rely on commercially available technologies and are released under the CERN‑OHL‑P v2.0 license.
