I only do my 'gardening' in containers and want to know if I can re-use the spent compost I have used last year when planting new plants.

As long as the compost/soil from the previous year is still healthy (i.e. there were no pest or disease issues), then you can reuse it. You may want to refresh it some by mixing in some new topsoil or potting soil.
