Step-by-step guide: Creating a scenario for a glass bottle

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

In the previous guide Step-by-step guide: Creating an LCA for a glass bottle, we covered the necessary steps to create a 33cl glass tea bottle 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 glass bottle can example. In this scenario, we would want to evaluate what would be the impact of making the bottle a bit thicker so we can reuse it 45 times instead of 30.

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 Thicker glass for 45 uses
   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 described, in a real life scenario this might involve many changes, but in this case, we will just increase the weight of the glass needed and the number of uses.
   1. On the left menu, go to the Composition > Bottle
      1. In the Component description section, increase the number of uses, from 30 to 45
      2. In the Glass section, increase the weight to 300 g.
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.
