ABERDEEN Royal Infirmary (ARI) is the first hospital in the UK to host a “reverse vending machine” – receiving vouchers in return for bottles and cans.

The trial initiative started yesterday, ahead of the nationwide Deposit Return Scheme (DRS) coming into effect in Scotland later this year.

The machine is situated next to the ATMs and WHSmith at the main entrance to the hospital.

Under the scheme, all buildings which include retail catering outlets must have the facilities for the return of plastic bottles, glass bottles and drinks cans.

The refund will be 20p per item and people will be able to choose between a voucher or a cash alternative.

During the trial there will be no cash alternative, however, people will receive a voucher worth 5p per item, up to the value of £2.50, when returning used bottles.

These vouchers can be used in the Aroma Cairngorm café.

Neil Duncan, waste management officer for NHS Grampian, said: “I am delighted ARI is hosting this trial and it’s my hope it will reduce litter on site and promote recycling.

“Anyone can use this machine to deposit their bottles and cans; they do not have to be a staff member, patient or visitor, though we expect most deposits will be made by them.”

The reverse vending machine is provided by recycling company TOMRA.

John Lee, TOMRA's vice-president for public affairs in the UK and Ireland, said: "We are delighted to be involved in this highly innovative project.

“NHS hospitals could play a key role in the success of deposit return once the scheme goes live.

“This project is paving the way for that success, showing how easy it is for everyone to play their part in it.”
