The move means that all plastic bottles of 500ml or less are to be made with 100% recycled plastic and will continue to be fully recyclable.
The first 100% recycled 500ml bottles will start appearing on shelves from September.
This means Coca-Cola Great Britain will increase the amount of recycled plastic material in smaller bottles from 50% to 100%.
The company is also completing the transition from plastic shrink wrap to cardboard packaging across all multi-packs.
A deposit return scheme is planned for implementation in Scotland by July next year, with England and Wales following thereafter.
Stephen Moorhouse, general manager at CCEP GB, said: “Increasing the amount of recycled plastic we use is a critical point in our sustainable packaging journey and reaching 100%rPET puts us one step closer to achieving our ambition of a world without waste – collecting and recycling a bottle or can for every one that we sell by 2025.”
