Is this asbestos / asbestos sheets?

Hello,
I have a garden with a prefab garden house from the GDR. I am currently cleaning up the tool shed and found these panels in a corner behind some wood scraps, but I don't know if they are asbestos panels. There are two different types, four coarse fiber panels measuring 2m x 0.60 and five solid ones about 1.20m x 0.70.
Does anyone know what material this is and how I can dispose of it? This stuff has probably been sitting in the corner for forty years. The owners have passed away and the heirs had no idea. Maybe someone here can help me.
Thank you very much in advance!

Asbestos in asbestos boards cannot be checked via the internet, that can only be done by a laboratory. Therefore, be careful about what everyone here guesses about the pictures.

The pictures look to me like fiber cement boards. Heraklith or similar. In my opinion, they were never produced with asbestos. If they really are Heraklith boards.

In the first pictures (the rough material) I would also say that it is Heraklith.

The other smoother panels I would suspect might be asbestos panels. But that is all speculation.

I would at least wrap the 5 panels in foil and then take them to the landfill. And then dispose of them there as asbestos.

With photos, it is always difficult to identify asbestos in asbestos boards. The thin boards could also be old carpets; you simply can't tell.
