Digital Product Passport
Complete transparency from grain to glass
What is a Digital Product Passport?
A Digital Product Passport (DPP) is a structured set of digital data about a product, accessible via a QR code, RFID, or NFC tag. It aims to improve transparency regarding sustainability, materials, and production, support the circular economy and traceability, and comply with the European Ecodesign for Sustainable Products Regulation (ESPR) activated since 2024.
