Plan to recycle liqueur (10)
I believe the answer is:
chartreuse
'liqueur' is the definition.
(Chartreuse is an example)
'plan to recycle' is the wordplay.
'plan' becomes 'chart' (charting is a kind of planning).
'to recycle' becomes 'reuse' ('reuse' can be a synonym of 'recycle').
'chart'+'reuse'='CHARTREUSE'
(Other definitions for chartreuse that I've seen before include "Pale green-yellow colour" , "The spirit" , "Carthusian liqueur" , "drink" , "Green or yellow liqueur made by monks" .)
