As of this Month the
TetraPak recycling website have reintroduced a PDF of addressed labels so that you can send them your recycled cartons.
(Click the 'DOWNLOAD LABELS link on the right hand side of their site )
Unfortunately postage does have to be paid but if your local Council doesn't recycle these cartons ~ there is an alternative to 'landfilling' them
Their
Map of Local Authority 'interest is quite an eyeopener lol !!
