The availability of digital tools is key for reproducible, robust, and transparent analysis. Life cycle assessment has become a well-established tool to perform environmental assessment of products and systems. However, despite the existence of diverse commercial software, data availability is still one of the major limitations. This paper introduces one database that aims to shed light in the analysis of electric and electronic equipment: the database of SEmiconductors and other components (DoSE®) and its use along with the Life Cycle Assessment database (LCADB®). DoSE® is a database that aims to provide data for a better analysis of electronics. It contains information of the material composition of semiconductors and other components, and a second section where the material composition of printed circuit boards can be modelled. Data from DoSE® are exportable to excel format to allow for a further use. It can also be exported as an activity to the LCADB® database to develop new life cycle inventories of electronics. All these functionalities are due to be further expanded and tested for the case of batteries and electronics in electric vehicles as part of the digital platform for circular economy developed in the scope of the DigiPrime project.
