Step-by-step guide: Creating a scenario for an aluminium can

This guide shows how to create a scenario over an existing product (a 33cl aluminium can) to see how changes in the existing product would affect the LCIA.

In the previous guide Step-by-step guide: Creating an LCA for an aluminium can, we covered the necessary steps to create a 33cl aluminium can in Pilario and obtain its environmental impact. Here, we will show how we can make ecodesign changes in our product and see the impact on the results.

Making a test scenario

One of the most powerful features of Pilario is the ability to create scenarios, that is, perform  ecodesign improvements to see the impact of those changes against the original product.

Let's continue with our aluminium can example. In this scenario, we would want to evaluate what would be the impact of replacing the machinery used to manufacture the almunium body with a more efficient one which uses less electricity (the ficticious machine is called AluShaper 3000 which we will use in the name of our scenario)

Let's see the steps needed to create a scenario and see the results:

1. In the upper right corner, go to the Actions button and select Create scenario
   1. Notice how we have changed from the Product page to the Scenarios in the left menu
      
2. This will duplicate our product and will bring us to its page, we can change the name an description to identify our scenario later
   1. In the name append AluShaper 3000
   2. In the description you could include something that could help you understand better this scenario, in this case, we don't add anything as the name is descriptive enough
3. Perform now the changes of this new process, in a real life scenario this might involve many changes, but in this case, we will just reduce the electricity used to produce the body of the can
   1. On the left menu, go to the Manufacturing > Main body > Almunium body. Remember that this is the single manufacturing step, but in a real life scenario you might have several steps.
   2. Change the Electricity consumption, from 1.42 to 1.38 kWh/kg in
4. Expand the results tab (via the arrow on the upper right corner)
5. Navigate through the results and compare the fictional product and the real one in any of the tabs.
