I've only started gardening this year. I have some raised beds, 3m x 1m
each, in which I'm trying 'square foot gardening' (hampered mainly by
the
slugs and local cats) and a lot of tubs and pots.

What do I do with spent compost from the pots and tubs? I've been doing
a
form of crop rotation in some tubs - peas followed by carrots, for
instance - but I've got a good 100l of compost that I grew potatoes in
that I know I can't grow the next set of potatoes in, in case of
disease.
So what can I do with this compost? I'll use some of it to fill up the
raised beds but I can't do that every year. Does it go in the compost
bin
to help out there?

I've just realised I can shove a fair bit of it on the borders but even
so, I'll take answers!

A 100L of compost will easily get lost on the raised beds you mentioned.
It's fine on the compost or anywhere in the garden.

as long as the compost contains no nasties (as discussed by others) it can
go back in to a compost pile or be mixed with fresh compost, it can be used
on a lawn if you are planting new seed, it can go under a tree or hedge as a
mulch, fill for a hole or gully, given to a neighbour who is building a
raised garden, used on clay soils to add organic matter etc etc. Some of the
nutrition may be gone from it but as a soil amendment it is still valuable.
You are only bounded by your imagination.
