Gluttons with intention to find kitchen waste (8)
I believe the answer is:
pigswill
'kitchen waste' is the definition.
(I've seen this before)
'gluttons with intention' is the wordplay.
'gluttons' becomes 'pigs' (I've seen this in another clue).
'with' is a charade indicator (letters next to each other).
'intention' becomes 'will' (will is a kind of intention).
'pigs'+'will'='PIGSWILL'
'to find' acts as a link.
(Other definitions for pigswill that I've seen before include "Scraps for swine" , "waste matter?" , "Refuse" , "kitchen waste" , "Scraps of food" .)
