I. Structural design optimization
   1. Modular disassembly
   Battery, cartridge, atomizer, casing and other components are designed as independent modules, which can be connected by snap fasteners / magnetic suction, avoiding glue bonding or welding.
   Case reference: a brand launched a “building block” e-cigarette, users can disassemble it in 5 seconds with their bare hands, and each part is recycled separately.
   2. Anti-mixing design
   Different colors or textures are used to identify parts made of different materials (e.g. red for batteries, blue for plastics) to reduce the difficulty of recycling and sorting.

Material Selection Innovation
   3. Single material application
   Use a single recyclable material (e.g. polypropylene PP, PLA) for parts such as shells and cartridges, and avoid composite materials (e.g. metal-plastic mix).
   Technological breakthrough: “All-plastic biodegradable atomizer” developed by an enterprise in Shenzhen has passed EU EN13432 certification.
   4. Easy Separation Coating
   Using water-soluble coating on the surface of metal parts, the plastic layer can be peeled off by simple water washing to enhance the separation efficiency.

Intelligent assisted recycling
   5. Digital Recycling Guide
   The device has a built-in NFC chip, and after scanning the code, it jumps to the “Shenzhen Garbage Sorting” applet, which provides personalized animation of disassembling and recycling steps.
   6. Lifetime reminder system
   When the remaining capacity of the battery is less than 10%, the battery management system will push the recycling reminder through the APP and associate it with the nearest “Dandelion Program” recycling point.

Incentive mechanism implantation
   7. Traceable Recycling Label
   Each device is equipped with a unique QR code. Users can redeem a 5% discount coupon at the brand mall after scanning the code and uploading the recycling voucher.
   8. Recycling Points System
   Recycling old equipment can be exchanged for points, which can be used for subsequent purchase of goods.

V. Compliance Design
   9. Standardized Interface
   The battery adopts USB-C universal interface, which is compatible with existing electronic device chargers and reduces the amount of waste of specialized chargers. 10.
   10. Anti-leakage structure
   Cigarette cartridges are designed with double seals to prevent residual nicotine contamination and reduce the difficulty of recycling and pre-processing.

Industry Synergy Program
   11. Shared recycling bin design
   In cooperation with convenience stores, a pop-up recycling bin is embedded in the bottom of the device, so that users can directly drop it off at the store's smart recycling bin.
   12. Reverse Logistics Tracking
   Adopt blockchain technology to record the full life cycle data of the equipment from production to recycling to ensure compliance with the waste recycling management practices of the destination country.

VII. Education and publicity
   Add information on how to properly recycle e-cigarettes in the form of large fonts and colorful pictures on the packaging and product manuals, including how to disassemble each component, how to find recycling sites and the importance of recycling. At the same time, print environmental slogans on product packaging, such as “Recycle e-cigarettes, guard the green home”.
   Regularly organize environmental protection promotional activities, such as going into communities, schools, office buildings and other places to carry out lectures on e-cigarette recycling, inviting environmental protection professionals to explain recycling knowledge, and demonstrating on-site the dismantling and recycling process of e-cigarettes. On social media platforms, publishing environmental protection promotional videos, which include the environmental hazards of e-cigarette waste, the correct recycling method and the recycling incentive mechanism, etc., and improving the publicity effect through topic interaction and lucky draws.
