Hello,
I've previously gone to the recycling days arranged in Meath. I think they take place about once per month, at different locations...
You can physically see the documents being put into the relevant shredding truck, where they are shredded in front of you. What's more, it's free for paper recycling.
I'm not here to give anyone a plug, but a certain independent councillor (let's just call him Joe) in Meath regularly promotes these events, so maybe contact him for a list of upcoming venues.
