It's currently operated in Dublin. Barcode on back of each of 3 bins (recyclables, non-recyclables and organic). Recyclables and organic are free, and non-recyclables includes a quota of x kg per month included in your monthly fee. You pay extra per kg if you go over the quota for non-recyclables in any month. The system encourages recycling, but at the risk of people contaminating the (free) recyclables bin with non recyclable material.
