A café in Dublin City Centre will only serve takeaway coffee in keep-cups from next year.
Bread 41 on Pearse Street said it wants to get behind the movement against plastic waste.
The café is already trialling the ban on single-use cups on Mondays – and has pledged to bring it in fully in the New Year.
Owner Eoin Cluskey says the policy has got a mixed reaction so far.
“I have a fabulous email I got that says: ‘No WiFi, no cups, no business from me,’” he said.
He said the full-time ban will be in place from February – but people who don’t own a keep-cup won’t be turned away.
“We are introducing a scheme where we will have our cups and you can put a deposit down and take a cup with you,” he said.
“We are not trying to discourage people away from it. We are just trying to be part of a solution to a massive problem.
“We are all aware of waste. This is a waste movement that I am going to be behind.”
Earlier this year a Government-funded study found that up to 200 million coffee cups are thrown away in Ireland every year.
The Recycling List Ireland study found that 528,000 are thrown away each day – which works out at just over 366 a minute.
The group warned that the cups cannot be recycled in Ireland and have to be disposed of in general waste.
