| Sample | PP-WT-003 |
| Plastic Type | Polypropylene (PP) |
| Molecular Formula | (C3H6)n |
| Color | White |
| Common use | Disposable plastic cup |
| Degradation details | Exposure to environmental conditions (it was in contact with soil for a long time) + the sample was introduced in liquid nitrogen for 15 minutes and then crushed (flattened) with a hammer |
| Time of degradation | 10 years of environmental degradation + 15 minutes of accelerated degradation conditions in the laboratory |
| Sample description | The sample shows visible signs of degradation (it is covered with dirt). After the liquid nitrogen treatment, the sample was very fragile to mechanical stress and broke very easily into small piecies |
