One of the joint winners was the Ocean Dollar, created by Hueck Folien to demonstrate its eco-friendly commitment and credentials. Inspired by the hidden depths of the ocean, the note includes a number of recycled components, including aluminium, paper and PET.

The micro-optics Optomove® security thread is made from recycled PET and aluminium, achieving 53% CO2 savings through the raw material used. The Reef foil stripe, featuring optical nanostructures and Trilumic®, is also made from recycled PET and aluminium, achieving 26% CO2 savings .

The substrate, EcoBreath® paper, was developed by BP Security in partnership with Casa da Moeda do Brasil, and allows the recovery and reuse of fibres from banknote waste to produce recycled security papers for banknotes and passports,
