Car park operator CitiPark has launched a programme at the Merrion Centre, which will run throughout October.
Drivers can bring plastic bottles that are 500ml or larger to quality for the free parking – but CitiPark will take any sized bottles to recycle.
Each 500ml bottle equates to a 20p discount on the cost of parking.
The collected bottles will be recycled into usable items such as chairs, shirts and toys.
The initiative is being accompanied by a week of recycling and sustainability programmes, which aims to bring together retailers and other organisations at the shopping centre during the week of 22ndOctober.
Charlotte-Daisy Ziff, Head of Corporate Social Responsibilities at CitiPark and parent company Town Centre Securities said: “Here at CitiPark, we believe that we all have a part to play in ensuring the preservation and betterment of our environment for future generations.
“So this promotion not only offers our customers the chance of free/discounted parking but they can also get rid of their waste plastic bottles and contribute to the protection of the environment at the same time: it’s a win-win all around! We hope that as many people as possible will get on board.”
The free parking is not eligible for season ticket holders, partnerships, permit holders and members of staff.
