All register extracts can also be checked without an account in the biogas register:
Check register excerpt
There are two procedures: Audit with the biogas register extract number and audit with the biogas register extract file (PDF). When checking the extract number, it is displayed whether a corresponding biogas register extract has been issued by the Biogas Register Germany. This extract can then be downloaded again as a PDF. When checking the extract file in the original output format (PDF), the biogas register extract to be checked is temporarily transferred to the biogas register and an electronic comparison of the documents is carried out.
