A business can transport parcels in rigid plastic crates or corrugated cardboard boxes.
The table gives the manufacturing data for one container.
| Type of parcel container | Water used in dm3 | Energy used in MJ |
|---|---|---|
| Corrugated cardboard box | 10 | 7 |
| Rigid plastic crate | 35 | 200 |
Over 100 deliveries, the business would use one rigid plastic crate or 25 corrugated cardboard boxes.
