中国二手循环实践再登联合国气候大会，转转以标准化质检推动资源循环利用

Summary 1: Zhuanzhuan turns the safe reuse of second-hand devices into a verifiable process, helping general readers understand how second-hand transactions can reduce risk.

1. The platform uses a C2B2C model; official quality inspection standardizes non-standard second-hand goods, giving sellers reasonable pricing and buyers after-sales protection.

2. In practice, inspection has four steps: photo documentation uses standardized equipment to capture images and AI to mark defects; functional testing is automatically determined by a proprietary app with engineer support; X-ray non-destructive testing uses AI to identify signs of repair, with teardown re-inspection only for doubtful cases; finally, data is securely erased with a full audit trail, generating a digital identity file.

Summary 2: Platform scale and green outcomes provide context for judging the credibility of second-hand circulation.

1. By the end of 2025, registered users exceeded 400 million; door-to-door plus store coverage reached 1,000 cities, with more than 1,500 offline stores.

2. Cumulative carbon emission reductions reached 6.3482 million tonnes and energy savings reached 8,712 GWh; two practices were included in the 2026 list by the Education and Communication Center of the Ministry of Ecology and Environment.

3. Zhuanzhuan has participated in the UN climate conference for four consecutive years and co-initiated a joint initiative of circular economy companies.

Summary 1: Zhuanzhuan strengthens brand trust and green image through inspection standardization, exposure at the international climate conference, and national-level case recognition.
