my phone was broken i need ti clear it before recycle it

Have a look at this support article:

What to do before you sell, give away, or trade in your iPhone or iPad - Apple Support

Of course what you can actually do depends upon the how "broken" the phone is.

If it can still boot you can try the things you can do as if you had already given away the device and no longer had access to it. This support article may have useful information in that context --> If your iPhone, iPad, or iPod touch is lost or stolen - Apple Support

Lastly, if the very good options provided in the replies so far don’t help, always keep in mind that any data stored on your iPhone is VERY securely protected by it’s passcode.

If your passcode is truly secure - preferably long - and not easily guessed, your data will remain quite well protected.

Might be worth a try to see if you can erase the phone using Find My.
