I inherited some bindweed with the raspberry canes that I got for free, in the communal area (yours for the taking) at our allotment site.
It has been present for the last two seasons, it has never been given a chance to take hold.
As soon as it sticks it’s head above ground I pull it up.
As these canes have not been productive at all this year, it is my intention to take them out and take them to the communal compost area, it’s where I take all my rubbish.
I take nothing from this compost heap, especially as I put my odd bits of marestail in there as well.
There is no solution as far as I know other than pulling it out.
The guy on the plot next to me has an infestation of it in with his blackberries and he knows he is going to have a mare of time getting rid of it.
Burn the bits you do get out, do not compost it, that is the only solution, it is like marestail it is is persistent but eventually if you essentially cut it off from light over time you will weaken the roots and kill.
Time is the only thing do not let it get a foothold again and you should be fine.
