The sustainable use of waste paper is a key component of a resource-efficient circular economy. In the long term, our system will serve as a certification and verification tool for paper recycling along the entire value chain. Through NFT-based certificates stored on the blockchain, we aim to offer a globally recognized and verifiable standard that demonstrates compliance with environmental and supply chain diligence regulations. Through blockchain technology, we enable traceability and certification from the point of collection to the final paper product.
