I'm trying to understand if there is a way to use the Bitcoin blockchain to record information. Say I am a business and would like to publish information to my clients through the Bitcoin blockchain; information that would therefore 1) be publicly available, 2) fully trustworthy (rather trustless) since verified and part of the Bitcoin network, and 3) be hashed/illegible to anyone but the client with the right key.

Let's take an example. Is it possible to use Bitcoin for example in a supply chain tracking business?

I guess what I am asking is, is it possible to use the Bitcoin blockchain for other use cases than as output of Bitcoin nodes verifying a new block and locking it to its predecessor?

I tried to search but didn't find anything (or I'm not a good searcher).

Thanks for any help.

The blockchain is not really intended to fill it with stuff other than bitcoin transactions, but you can add messages to your transactions. Example:

So you could post a link there, or just identify yourself as owner of a certain BTC address and sign messages with your address, but I don't see how you can actually put big walls of text there, let alone attach pictures or other things.
