Experimental Study of the Effect of a Solid Wing Conveyor on Marine Debris Collection
AI summary Read the abstract
This experimental study tested how a solid wing conveyor on a boat collects floating marine debris, evaluating collection efficiency as a function of boat speed and wave conditions.
Marine debris is a global problem that has not been resolved. This has encouraged the emergence of marine debris cleaning technologies, one of which is a conveyor ship. However, how effective conveyors are in collecting waste has not been studied. In this paper, experimental research on conveyors as marine debris collectors is investigated. The capability of catamarans with or without solid wing conveyors to collect marine debris is explored. Three kinds of marine debris collection models are used: no-wing conveyor, a 12.5-cm-long wing conveyor, and an 18.75-cm-long wing conveyor. Artificial marine debris (AMD) is spread on the water surface in a static tank. Then, a marine debris collector model is pulled using threads tied to the ship's body. This is done several times starting from a low speed and progressing to a high speed. After the experiment, the effectiveness of marine debris collection from these three models is analysed. In addition, the cause of marine debris not being caught by the model is investigated. This work proposes a new approach to evaluate the effectiveness of conveyer wings in marine debris collection. Based on AMD movement pattern analysis, it is suggested to operate the device at a low speed because the collected AMD ratio is high and the lost AMD ratio is small.

Modeling and Control of a Floating Marine Litter Collection Device
AI summary Read the abstract
Marine litter collection devices offer a way to intercept plastic waste in rivers and estuaries before it reaches the open ocean and fragments into microplastics. This study developed mathematical models to simulate and control the behavior of a floating collection device called Waste Out of Water (WoW), optimizing its performance under different current and wind conditions. While focused on engineering and control systems rather than microplastic science, effective debris capture technology is an important tool for preventing new microplastic formation at sea.
