The research led to the development of a specialized knife for cutting waste ropes and nets from marine waste. The composition of the manufactured knife was analyzed with XRF equipment, and the main components were iron and chromium, with small amounts of molybdenum, vanadium, and nickel. Vickers hardness measurements showed similar hardness values at the surface and center, and a metallographic microscope examination of the knife surface texture revealed a fine-grained martensite structure. The low heating value of the waste rope and waste net was measured, and the low heating value was higher than 3,500 kcal/kg, which is the quality certification standard for solid refuse fuel.
