Rubbish recycling set amid predicament (6)
I believe the answer is:
jetsam
'rubbish' is the definition.
(I've seen this before)
'recycling set amid predicament' is the wordplay.
'recycling' indicates an anagram.
'amid' is an insertion indicator.
'predicament' becomes 'jam' (jam can mean a tricky situation).
'set' anagrammed gives 'ets'.
'ets' inserted into 'jam' is 'JETSAM'.
(Other definitions for jetsam that I've seen before include "Cargo deliberately thrown overboard to lighten ship" , "Unwanted material thrown overboard" , "Stuff cast overboard" , "that lands on shore" , "stuff washed ashore" .)
