Recycled urine bottles 'pee green' (6)
I believe the answer is:
unripe
'green' is the definition.
(I've seen this before)
'recycled urine bottles pee' is the wordplay.
'recycled' is an anagram indicator.
'bottles' is an insertion indicator ('bottle' can mean to contain).
'pee' becomes 'p'.
'urine' is an anagram of 'unrie'.
'unrie' enclosing 'p' is 'UNRIPE'.
(Other definitions for unripe that I've seen before include "Not ready for picking" , "Immature" , "Punier (anag.)" , "Not yet mature" , "Still green?" .)
