No basket lying around with a garbage bag in there?
And otherwise for nutrients you can also take a bananapeel ans stick it in a jar for 2 days. The nutrients coming from the peel in the water also do wonders!

I'll probably use some then.
And no: I have no container available at all.
..at least not one, where I am willing to drill a whole into.
