Building Circularity V2: End of Life

By default, materials will have assigned an end-of-life process. These processes are based on the material type, and you will notice that there will be differences in the end-of-life processes depending on what material options you use. 

All materials have a default end-of-life (EOL) scenario based on the material type. The scenario models the processing chain applied to the material throughout all the lifecycle phases. 

If you click on the EOL Process input, you can select the different scenarios applicable to the material type. Select here what is appropriate for your project. 

The EOL scenario covers the processing chain for all life-cycle phases, but you can now control whether the same processing is applied for A5 stage (EOL Process A5) and C3-C4 stage (EOL Process C3-4). Additionally, for the C3-C4 stage, you can now control the efficiency rate by inputting percentages into Recovery rate (C3) and Disposal rate (C4). The two inputs will automatically balance to equal 100%.

When selecting a scenario from EOL Process, the above inputs are automatically populated by the scenario's values, and changing the scenario updates the values (see below).

In this example, changing the scenario in the EOL Process input has changed the processing type from Downcycling (crushing of aggregate) to Disposal (landfilling), and the percentage of material going to landfill has changed from 20% to 100%.

This new feature gives you the option to have more granular control over the processing of wastage and materials if it is needed, but still use the scenarios if that is more appropriate for this stage of your project.

Any changes to the processing types or share of material do not affect life cycle assessment results and are only used for documenting circularity.
