SINGAPORE – Singapore is creating what is said to be a world-first digital “passport” for plastics to boost recycling as its sole landfill in Semakau is running out of space in 10 years.

The records are written on a blockchain, allowing the irrefutable passport data about the plastic’s origin, composition, reuse cycles and disposal to be exchanged among plastic manufacturers, recycling firms and the authorities for auditing purposes.

The multi-year effort is being led by A*Star, in partnership with Nasdaq-listed Security Matters.
