People in Louth urged to reduce their waste while socialising outdoors 2.25 million single use plastic bottle and cups are used in Ireland each bank holiday weekend Reporter: '); Planning ahead for dining in the great outdoors this June bank holiday weekend will help reduce waste, keep millions of single use cups, bottles and cutlery from ending up in our waste system or as litter, and reduce costs to local businesses according to My Waste. Each day in Ireland more than half a million single use coffee cups, and close to a quarter of a million single use plastic bottles are used - the equivalent of 2.25million single use cups and bottles over a bank holiday weekend.
