Waste, rubbish (6)
I believe the answer is:
refuse
<span class="explanation-format__ClueExplanation">I believe this is a double definition.<br/ ><br/ >'<span class="explanation-format__original">waste</span>' is the first definition.<br/ ><span class="explanation-format__explanation">(refuse is a kind of waste)</span><br/ ><br/ >'<span class="explanation-format__original">rubbish</span>' is the second definition.<br/ ><span class="explanation-format__explanation">(refuse can mean rubbish or garbage)</span><br/ ><br/ ></span>
(Other definitions for refuse that I've seen before include "Say no to - rubbish" , "Trash" , "Decline to accept - waste" , "Say no to - waste" , "Turn down; waste" .)
