Cardboard containers for food that contain moisture need to have a laminate applied to stop the cardboard from getting soggy and falling apart. This makes the cardboard non-recyclable without specialist facilities to separate the 2 elements. Unfortunately, we do not have enough of these facilities available in the UK to cope with the volume of cardboard containers. For example, the sandwich packs in every supermarket that we assume are recycled currently go to landfill because the UK cannot recycle them efficiently or cost-effectively.
