Trajectory model of macroplastics on land is a strategy for preventing and mitigating plastic pollution in the environment and a component of its management strategy. However, basic data related to the dynamics of the movement of plastic waste on land as the main data in the model design process has been limited. This research was conducted to meet this need by reviewing the influence of environmental factors such as wind, surface runoff, ground surface, and slope on the movement of plastic waste on land. An empirical approach simulating experimental scenarios and observations of five varieties of plastic on variations in wind, surface runoff, ground surface, and slope was used to collect data on the dynamics of plastic movement. Wind parameters are simulated using a fan constrained by a net tunnel, whereas surface runoff parameters are simulated using a pipe system and containers. As research plots, asphalt roadway, bare land, and cutting grass on both flat and sloping terrain were chosen. The results show that (1) each type of plastic has a wind speed threshold that varies depending on the environmental factors being traversed where plastic bag can be moved by wind in the range of 0.8 – 1.6 m/s, foam food container 1 – 1, 8 m/s, plastic bottle 0 – 3.5 m/s, mica plastic container 1.3 – 3.7 m/s and multilayer film dry food packaging 1.7 – 3 m/s, (2) there are three classifications out of five types of plastic based on their response to the wind factor: the plastic group that is easily moved by the wind, the plastic group that is difficult to be moved by the wind and the transition group whose response is between the two groups, (3) surface air discharge runoff which can move five types of plastic on ground surface variations and slope in this study is 1 L/second, (4) wind potentially moved the plastic when plastic is in an open area, while surface water runoff potentially moved the plastic when it enters the drainage system, and (5) ground surface variations, and slope has a significant effect on the movement of plastic waste on land. Based on these results, the type of plastic, the ground surface variation, and the terrain slope can serve as inputs for the development of a land-based plastic waste trajectory model.
