A waste receptacle holding most of Stan's refuse (7)
I believe the answer is:
abstain
'refuse' is the definition.
(to abstain from something is to refuse it)
'a waste receptacle holding most of stan's' is the wordplay.
'waste receptacle' becomes 'bin' (I've seen this before).
'holding' indicates putting letters inside.
'most of' means to remove the last letter.
'stan' with its final letter taken away is 'sta'.
'bin' going around 'sta' is 'bstain'.
'a'+'bstain'='ABSTAIN'
(Other definitions for abstain that I've seen before include "Keep away from drink" , "Choose not to do something" , "Take no part" , "go on wagon" , "Desist" .)
