Hey 
I would like to know the source of the on site wastage percentage when “Global” has been selected in the LCA parameters.
I also wondered whether it makes a difference for construction site wastage whether a building or an infrastructure project is considered?
Thanks for your help in advance!

Hi Theresia,
There is no single source available that has information on every product type. We use a mix of different sources. A good resource that has waste information on a wide range of products used to be the publisher Marcel Dekker, which we attribute to many product category percentages. Construction waste percentages in building and infrastructure currently use the same source.
The regional settings often come from regulatory sources that mandate the waste percentages.
If you are interested in a specific product, I can find the source for you. They are usually research papers or published journals.
