The drawer - where you model your cycle
The drawer - where you model your cycle

The drawer shows all the inputs of your cycle as a sortable list.

Updated over a week ago

When you create a new cycle either from a template or from scratch you can access all the inputs in what we call "the drawer".

In the drawer you view, edit and add inputs for the selected stage.

Every stages (Production, Distribution, and Use & End of Life) have their own drawer to help you keep your models tidy.

Here is an example of the drawer of the Production stage.

If the numbers are too big or small in the input fields or calculated values, they are shown using SI unit prefixes to make them easier to read.

For example, a minimal impact may be shown in milligrams, i.e., mg is displayed instead of in grams.

Processes tab

The drawer opens with the Processes tab on the right by default.

The Processes tab shows a list of inputs to the selected stage.

You can add new inputs or edit how much of that input your process needs.

  • Each time you edit, the system will recalculate realtime and update the diagram on the left.

  • The specific values of the impacts of each process are shown on the right and represented in the diagram.

The processes input list is ordered based on your selected impact category.

Sorting processes

By default the list is ordered based on your currently selected impact category (climate change in the example). You can change that order with the Sort button.

Changing the impact category

By default the list shows the values for your currently selected impact category (climate change in the example).

  • You can change the impact category by clicking on the leaf icon and selecting the desired impact category or form View drop-down menu in the cycle view

Searching for processes inside your list

Search for a specific process inside your list by clicking the search button. Typing your search word into the search bar will automatically search and show you the related results.

Viewing process information

Inputs are themselves also processes, so you can navigate them by clicking on their name. If they have processes inside them, you will open a drawer like the current one.

Some processes look a bit different. See also the article about various processes in the Earthster Knowledge Base.

Exchanges with Nature tab

The elementary flows are the core of Earhtster's calculations that mostly happen behind the scenes.

The Exchanges with Nature tab lets you edit the list of elementary flows that have a direct onsite impact on nature, i.e., your product's or service's direct emissions.

As with processes, you can edit the values directly here and immediately see the effects on your cycle.

Info tab

The Info tab lets you see and edit metadata and perform actions on the selected process.

The drawer will adapt to the type of process you have selected. The below image is an example of the info tab for a custom process.

In the description, you can record any assumptions regarding this process. For example notes on why you selected it, how you gathered the value for it, any conversions, etc.

Here you also find buttons to perform the most common actions.

  • Swap process

  • Export as a cycle

  • Delete process
