AADP

 

Description

The anthropogenic stock extended abiotic depletion potential (AADP) was develop by the Technical University of Berlin (TU Berlin)

It is a supplement to the traditional abiotic depletion potential (ADP) where the resources present in products and landfills are taken into account.

 

Characterisation

 

Current ADP indicators excluded materials stored in the technosphere, the anthropogenic stock. Total anthropogenic stock is determined as the accumulated extraction rate since the beginning of records, in approximately 1900, until 2008 based on data from the U.S. Geological Survey. It is assumed that the amount of materials mined before is negligibly low in comparison to the large volumes and rates extracted since 1900. This is split between employed and deposited stock. Employed stock is the resource that is still in circulation. It is composed of resources in use and hibernating, which is resources in storage before eventually being discarded. Expended stock is the total amount of resource that has been discarded. It is made up of deposited and dissipated stock.  The deposited stock, e.g. in landfills, enables future recovery whereas the dissipated stock is emitted to the environment in a form that makes recovery almost impossible e.g. water emissions of metals.The implemented AADP is the total anthropogenic stock (excluding the dissipated stock) added to the conventional ADP factors. It is indicated relative to antimony as has the unit kg Sb-eq. [Schneider, 2011].

 

Normalisation and weighting

 

Normalisation and weighting is currently not developed for AADP.
