In this article, we cover the specific packaging model, and its specific submodels: PackagingPET and PackagingGlass.
Description of the model
Pilario’s LCA Packaging model is your key to tackling environmental packaging challenges.
What manufacturing processes can I use for my products?
There are several manufacturing process available in Pilario for the manufacturing step. By selecting one or another will populate the manufacturing loss and energy consumption with the default values defined in the model. The user can always overwrite one or many input parameters in case they know more specific values. The following process are available:
- Custom process
- Bottle blow moulding
- Tray sheet extrusion
- Tray sheet co-extrusion
- Tray lamination
- Tray metallization
- Tray calendering
- Tray thermoforming
- Masterbatch
- Multilayers blow moulding
- Bottle injection
- Multilayers co-injection
The default manufacturing process is the "custom process" where the user must input the values themselves.
See, in the example below, how changing the manufacturing process from "custom process" to "Bottle injection" applies a default manufacturing loss of 0.6 and an energy consumption: natural gas consumption of 4.4391 MJ/kg in and electricity of 0.6223 kWh/kg in.
According to which amount of material should I fill the energy consumption in the manufacturing stage?
Pilario expects you to put the energy consumption (natural gas, LPG, diesel, etc) based on the amount of material that enters this step. This amount of material is called weight in and takes into account the manufacturing losses, therefore you should always provide that value when known in the specific Manufacturing loss input parameter. Please note that this value might be prepopulated when selecting a specific manufacturing process, as explained in the previous section.
Let see the following example where we are producing via bottle blow moulding a bottle of 32g of plastic.
1. We have input in the composition of the product 32 g in the PET weight.
2. In the manufacturing stage, we have created a Step 1 where we have selected Bottle blow moulding as the manufacturing process. This will apply a default Manufacturing loss of 0.3 % and an electricity consumption of 0.6223 kWh/kg in (the later is not shown in the picture).
If the user wants to overwrite the default value for the Energy consumption, they should consider the weight of 32.1 g, as displayed in the greyed field above. As per the formula:
