  abstract  = {This paper analyses the potential of digital information technology to enable the reliable provision of product information along the plastics supply chain. The authors investigate the possible contribution of a product passport equipped with decentralised identifiers and verifiable credentials to overcome information deficits and information asymmetry in the circular plastics economy. Through this, high-quality plastics recycling could be enabled on a larger scale than currently possible.},
