Go round, consumed by rubbish (6)
I believe the answer is:
rotate
'go round' is the definition.
(thesaurus)
'consumed by rubbish' is the wordplay.
'consumed' becomes 'ate' (eating is a kind of consuming).
'by' means one lot of letters go next to another.
'rubbish' becomes 'rot' (I've seen this before).
'ate' put after 'rot' is 'ROTATE'.
(Other definitions for rotate that I've seen before include "Turn round" , "Turn around as on axle or spit" , "Go around" , "Pivot" , "Turn around on axis or central point" .)
