ProBas database with almost 30,000 processes is now available in Nexus. For academic use the database can be downloaded for free. 

ProBas is a German dataset library originally provided by the German Federal Environment Agency (Umweltbundesamt). It includes unit as well as aggregated processes, for the following topics: Energy, Materials & Products, Transportation services and Waste. Two-third of the processes are representing Germany. But also other countries are represented by the data.
