Module D Reused/Recycled Product Tool (BETA)
This tool can be used to get an idea of a product's module D carbon emissions – emissions saved in the future by designing for some or all of the product to be reused or recycled. It is important to note that module D is a net result, not gross. So, if a product contains 95% recycled content and 95% will be recycled in the future, the module D result will be zero! For this reason, a gross result is also shown (not used for module D).
Enter the required information into the yellow fields. When done, the results will appear/update in the green fields.
| Product details | |||
| Quantity in building | kg | ||
| Enter the total quantity of the product to be removed from the building. E.g. at the end of the building's life, the total quantity installed. | |||
| Percent from a recycled/reused source | % | ||
| Enter the percent that is from a recycled/reused source. E.g. if a material is 30% recycled content, enter 30%. | |||
| Percent to be recycled/reused in the future | % | ||
| Enter the percent of the total quantity (above) to be recycled/reused in the future. E.g. if the end of life scenario is 60% of the material is to be recycled, enter 60%. |

One of the following approaches may be used for entering the emissions factors: - A: Total A1-A3 emissions approach. Enter A1-A3 emissions for the standard and reused/recycled product. This could be from an embodied carbon database like ICE or from BECD. A1-A3 data needs to be available for equivelant standard and reused/recycled content products. B: Point of subsitution approach. For the standard product: Enter total emissions upstream of the point of subsitution. For the reused/recycled product: Enter emissions from the end-of-waste state to the point of subsitution (the point of subsitution is when the reused/recycled input material subsitutes the standard input material). This approach requires emissions data for only part of A1-A3, which may be hard to obtain. Important: The same approach must be used for both the standard and reused/recycled product emissions factors entered. For Approach A, It is assumed downstream emissions from the point of subsitution are the same. If sequestered/biogenic carbon is inlcuded, it needs to be included for both. |

| See notes for standard product above. | ||
| Quality factor | (see notes) | |
| Enter a quality factor, equal to or less than 1, to reflect the functional performance reduction of the reused/recycled product vs the standard product. If no diference, leave as 1. |
