Pam.
I should think that the main objection to re using old compost is
the build
up of pests etc in the compost.
If you don't have to vast a quantity then you could sterilize it in
your
microwave, you would be surprised how much you could do doing say 3
lots of
say 2 litres a day ( a Pyrex casserole dish with lid works great)
over 2
weeks.

David, for how long do you typically leave the compost in the
microwave?
Do you dampen it before it goes in, or is the natural moisture in it
enough?
