There is a local company here that makes one of the best worm
composters available.
They have a whole system of 'circular' gardening, compost, grow, eat
the vegetables, compost the waste, grow the veggies.

I have no 'interest' in the company, but their product is great and I
thought those of you who have container gardens might be able to use
something like this. I really like the idea of recycling as much as
is possible and this is the perfect way to use up kitchen waste and
make great garden soil out of it.

Check it out.
