Wherein to put rubbish, broken nibs, etc. (4)
I believe the answer is:
bins
'wherein to' is the definition.
I can't judge whether this defines the answer.
'rubbish broken nibs etc' is the wordplay.
'nibs' anagrams to 'BINS'.
Though, I am not sure how this is indicated.
'put' is the link.
Can you help me to learn more?
(Other definitions for bins that I've seen before include "Rejects" , "Containers for wine or rubbish" , "Rubbish receptacles" , "aid to viewing" , "Containers for refuse" .)
