The Government has drawn up a list of the approved materials that can and cannot be placed in your household recycling (green) bin.
What’s in? Paper & Cardboard, Rigid Plastic, Tins & Cans.
What’s out? Everything else.
You can print out a page listing the approved materials with helpful photos.
The Recycling List Ireland website includes an interesting section (Why am I not on the list?) explaining why previously accepted materials are no longer permitted.
