The digital carrier of product life cycle information is the digital product passport, which uses a unique identifier to record the complete data of the product from raw materials, production to use and recycling. It is not only a key tool to achieve a circular economy, but also an important infrastructure for improving supply chain transparency and promoting sustainable consumption. With the advancement of EU battery regulations and other policies, the digital product passport is moving from concept to practical application.
How digital product passports improve product traceability
Each product is given a unique identity, and the digital product passport transforms the traditional linear supply chain into a traceable network. Information about each link of the product includes raw material sources, production processes, carbon footprint and other data, all of which are encrypted and recorded on the distributed ledger. The result is that any supply chain participant can verify product authenticity and protect commercially sensitive information.
In practical applications, the digital product passport of the clothing industry can record the place where cotton is grown, the location of the spinning mill, the dyeing process and many other detailed information. Consumers can know the complete journey of the product by scanning the label, which not only enhances brand trust, but also provides legal basis for regulatory authorities. As the technology matures, digital product passports will become a basic requirement for products to enter the market.
Why digital product passports are crucial to the circular economy
In the traditional economic model, the end of a product's service life often means resources are wasted. Digital product passports provide complete product composition and disassembly information, allowing recycling companies to efficiently classify and process discarded products. For example, electronic device passports will clearly indicate the content of rare earth metals and recycling methods, thereby greatly increasing the resource reuse rate.
The circular economy has such a requirement for products, that is, their recycling status must be considered during the design stage. Digital product passports are precisely the key core tools to achieve this goal. It will encourage manufacturers to select materials that are easier to recycle and optimize and improve product structure design. When recycling plants can quickly obtain the composition of product materials, the efficiency of the entire resource recycling system will be qualitatively improved.
What core information does a digital product passport contain?
The digital product passport contains three major categories of information. The basic attribute data category covers product specifications, material composition and safety instructions. The life cycle data category records carbon footprint, water footprint and other environment-related indicators. The recycling data category provides maintenance guidelines, disassembly methods and recycling processing requirements. These data together form a complete picture of the product.
Information is collected in accordance with the "necessary and sufficient" criterion, which not only meets the need for transparency but also prevents data complexity. Take battery products as an example. The passport will contain performance data such as capacity attenuation curves and optimal operating temperature ranges, as well as data on the recyclability ratio of key materials such as cobalt and lithium. This structured data lays the foundation for subsequent value discovery.
How businesses can implement a digital product passport system
When enterprises implement digital product passports, they must focus on two aspects: technical architecture and organizational processes. On the technical level, it needs to establish data interfaces with existing ERP and PLM systems, and select appropriate blockchain or centralized storage solutions. From an organizational perspective, it is necessary to form a cross-departmental team and clarify the responsibilities for data collection and the verification mechanism.
The implementation process generally uses a gradual approach, starting with pilots on core product lines and then gradually expanding coverage. The key is to build a data quality management system to ensure the accuracy and timeliness of passport information. Provide global procurement services for weak current intelligent products! The professional team can assist companies in selecting appropriate solutions and optimizing implementation paths.
What are the technical challenges facing digital product passports?
Data standardization, system interoperability, and privacy protection are the three major technical challenges faced by current digital product passports. There are differences in data formats in different industries and in different regions, which makes information sharing difficult. There are problems with the compatibility of various blockchain platforms, which in turn interferes with system scalability. At the same time, maintaining a balance between commercial confidentiality and transparency requires careful design.
Digital product passports achieve the required information sharing while protecting the core interests of enterprises. This is achieved by adopting international common data standards, developing cross-chain interoperability protocols, and using privacy computing technologies such as zero-knowledge proofs. Such technological breakthroughs can facilitate this situation, and technology suppliers are actively addressing these challenges.
What real value does a digital product passport have for consumers?
For consumers, digital product passports bring unprecedented product transparency. By scanning QR codes, consumers can check the authenticity of the product, know the production background, and obtain personalized usage recommendations. Especially in second-hand transaction scenarios, the maintenance history and remaining life assessment recorded in the passport provide a reliable basis for making purchase decisions.
Since consumers have more sustainable consumption choices after being able to compare the environmental performance of different products, they can rely on their purchasing behavior to support environmentally friendly companies. This market effect will help the entire industry transform in a green and low-carbon direction, and will ultimately benefit all members of society. Digital product passports give such choices.
When you are engaged in purchasing electronic products, will you pay more attention to the environmental footprint information of the product, or will you pay more attention to data related to the convenience of the maintenance process?
