Blockchain Consignment System for Marine Plastic Traceability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The current management systems for marine plastic debris lack a comprehensive and reliable traceability mechanism, making it difficult to ensure the authenticity and origin of recycled marine plastics, which leads to challenges in preventing 'green washing' and maintaining market integrity.
Innovation Solution
An electronic consignment note management system based on blockchain technology is introduced, which includes a cloud management platform and various service sites deployed on a blockchain network. This system utilizes a blacklist and whitelist mechanism, combined with a credit evaluation model, to verify and manage the electronic identities of service sites, ensuring the accuracy and traceability of marine plastic debris data throughout its collection, transportation, and disposal processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If self-declaration is used for verifying the source of marine plastics, then the verification process is simple and easy to implement, but the reliability and accuracy of source verification deteriorates, making it difficult to prevent green washing
Solution Approach 1:
The patent introduces blockchain technology as an intermediary mechanism between marine plastic collectors and buyers. The blockchain platform records and verifies the source, collection, and transportation information of marine plastics objectively, preventing green washing while maintaining operational simplicity for users.
Solution Approach 2:
The patent replaces the manual self-declaration mechanism with an automated digital verification system based on blockchain. Smart contracts and digital tracking replace human-driven verification processes, significantly improving reliability while keeping the user interface simple.
2Reliability
If a complete blockchain-based management system is implemented for marine plastic debris, then the traceability and reliability of marine plastic data is improved, but the device complexity and implementation difficulty increases
Solution Approach 1:
The patent divides the blockchain management system into multiple independent modules: collection terminals, transportation terminals, processing terminals, and a central management platform. Each module handles specific functions, reducing overall system complexity while maintaining comprehensive traceability through their interconnected operations.
3Ease of manufacture
If traditional hazardous waste management methods are applied to marine plastic debris, then the management process follows existing protocols, but the supervision difficulty increases and evidence chain completeness deteriorates
Solution Approach 1:
The patent implements real-time feedback mechanisms where collection, transportation, and processing information are continuously recorded on the blockchain and made visible to all stakeholders. This transparent feedback system simplifies supervision by providing automatic, tamper-proof records of the entire waste management chain.

AI summary
An electronic consignment note management system for marine plastic debris based on blockchain technology, which belongs to the field of marine plastic debris management, and comprises a cloud management platform deployed at the central node of the blockchain and service sites deployed at other nodes, wherein the cloud management platform is used for supervising the handover process of marine debris among service sites, and verifying the electronic identity of a service site that issued an marine debris transshipment order request by a blacklist and whitelist mechanism, wherein for an electronic identity beyond the validity period, a credit evaluation model is used to update the status and validity period of the electronic identity, and the marine debris transshipment order request issued by the service site in a blacklist is rejected.
