Rubbish by an item of furniture that can be turned around (9)

'turned around' is the definition.
The answer and definition are not the same part of speech. However, adjectives and past participle verbs occasionally mean the same thing.

'rubbish by an item of furniture' is the wordplay.
'rubbish' becomes 'rot' (both can mean nonsense).
'by' is a charade indicator (letters next to each other).
'an' becomes 'a'.
'item of furniture' becomes 'table' (table is a type of furniture item).
'rot'+'a'+'table'='ROTATABLE'

'that can be' acts as a link.
