ᐅ I am looking for the installation instructions or the exact name of the Ikea waste separation system.

Looking for the name and installation instructions for the shown waste disposal system.

Can anyone help – Ikea itself no longer has any documentation?

Take a look under the individual components. Maybe the name of the product is still listed there. But the whole thing strongly looks like Rationell to me, at least the waste bins...
