When visitors to the SSE purchase their first drink they will receive it in a reusable cup and will pay a £1 levy.
The purchased cup can then be exchanged for a fresh cup for each subsequent drink, without the need to pay the levy again.
Cups must be returned it to a designated collection point in the arena at the end of the event.
A spokesperson for the SSE Arena said the £1 levy was “essential to cover operational costs, including cleaning, sanitising, and transporting cups to a specialist washing facility in Carryduff”.
They added the SSE had been exploring the scheme since 2018, but had “lacked access to a local wash plant, making it unviable until now”.
“The £1 levy was introduced as a transparent approach to funding the scheme,” the spokesperson added.
“Any surplus from the levy will support the Odyssey Trust’s charitable and green initiatives, reinforcing our commitment to sustainability.”
