The below is an example of one of the LCA results for a package with the following characteristics.
- Material: Cardboard
- Weight: 3 kg
- Dimensions: 1600x1000x700 mm
- Material: Plastic (HDPE)
- Weight: 20 Kg
- Dimensions: 1650x600x550mm
For this analysis, the functional unit used was 1/1000th, i.e. the model compared the use of 1000 units of single-use cardboard packaging to a single unit of reusable plastic packaging used 1000 times (see table below for full comparison).
- Total saving: 5.1 tonnes of CO2 eq.
- 95 % reduction in CO2 eq.
- Around 1.31 Kg of CO2 saving per vehicle produce
A similar assessment was carried out for 418 packaging solutions that the OEM ultimately changed to returnable packaging. It was estimated that the total carbon emission savings were equivalent to around 1,328 tonnes of CO2.
Although the OEM reported cost savings significant enough to justify the implementation of returnable packaging, we are unable to report precise figures in this case study.
