One Click LCA offers adjustable end-of-life modelling capabilities. The purpose of this change is to provide users with more choices to consider the impacts of the end-of-life options used on a project. Note that the new EOL model is only possible to adjust in detail with Expert licenses.
How can you adjust the End of Life options for individual materials?
Step 1: Set new End of Life modelling options
For tools where this capability is enabled, Expert users can choose any of the following end-of-life modelling methods. This choice is made in the LCA Parameters query and applies to the whole project (to the exclusion of tools that do not apply the new EOL model).
Material-locked – material type-specific scenario.
Market scenarios, user-adjustable – Set of EOL scenarios available for material type. The default option is chosen based on the standard practice on the market. Users can adjust the options per item. Users can also choose the EPD EOL scenarios for specific products if they so wish.
EPD EOL scenario, user-adjustable – This uses the EOL scenario defined in the EPD (if defined). Users can also choose market scenarios for specific products in this case if they so wish
The market scenario method considers the state of waste management regulations in the country. If the country is considered to have highly regulated waste management with effective landfill taxes and recycling rates (e.g. most of Europe), materials are recycled by default. In markets where regulations and landfill taxes are lacking (e.g. the Middle East), most materials are landfilled by default.
Users can adjust these options from those available.
Step 2: Adjust the EOL process in the building material query
While on the building material query, you are able to adjust the EOL process for each row of data.
Step 3: Review results on the results page
On the results page, there are expandable results for the EOL options, which will either show only new or only old results.
The differences between the end-of-life options
The scenarios differ in several important ways as detailed below:
| Material Locked | Market scenarios, user-adjustable | EPD EOL scenario, user-adjustable |
Is it user-adjustable? | No | Yes | Yes |
Does it vary by country? | No | Yes | No |
Always the same default for specific products? | Yes | No (varies by where used) | Yes |
Always the same default for specific material types? | Yes (with few exceptions) | No (varies by where used) | No (varies by EPD) |
Always the same default for specific material types in a specific country? | Yes (with few exceptions) | Yes | No |
Influenced by local heat recovery for module D? | No | Yes | No |
Fail over if no EOL in EPD | None | None | Market scenarios |
