Table 2 Classification of plastic waste according to waste size [4]
From: A brief review on polyvinyl chloride plastic as aggregate for construction materials
Class | Size range | Transport pathways | |
|---|---|---|---|
Low density plastic (specific density < sea water density) | High density plastic (specific density > sea water density) | ||
Macro plastic |  > 25 mm | Floatation | Sedimentation |
Mesoplastic | 5–25 mm | Floatation | Suspension |
Microplastic (MP) |  < 5 mm | Floatation | Suspension |
Large microplastic (LMP) | 1–5 mm | Suspension | Aggregation-sedimentation |
Small microplastic (SMP) |  < 1 mm 0.2–1 mm | Aggregation-sedimentation | Sedimentation |
Nano plastic |  < 1 μm | Suspension | Aggregation |
