The paper-shell recovery project, which is centred on the internet+reproductive resource recovery model, integrates the recycling industry chain by digital means and provides easy and efficient door-to-door recovery services, with the following key features: first, the project model and positioning digitized platform driver-driven paper-shells perform “one-key-to-one-down” functions through micro-mail publics, micro-mails and apps, and, following an appointment on the user line, the recycler service at the agreed time. The model breaks the space-time limit for traditional recovery and addresses the problems of late recovery of used and end-of-life items and the lack of transparency of processes. Multi-scenario coverage covers project focused regeneration resource recovery, which targets enterprises, businesses (e. G. Malls, supermarkets, writing buildings) and community residents, building a chain-wide system of “front-end recycling-middle-cleaning-back-end sorting” through an off-line and off-line recovery network. The system automatically matches the regional recycling staff and provides standardized packing, weighing and settlement services after the service-flow users have submitted orders through the platform. The platform tracks the status of orders in real time and ensures transparency of services, such as access to recovery progress and feedback on returns. The combination of environmental and economic benefits and the benefits that users derive from recovery, together with environmental awareness-raising, such as the population's cumulative record of 129 times, contributes both to the recycling of resources and to green urban development. The project aims at “green recycling + low-carbon environmental protection”, for example, by treating 60 tons of recyclables per day at the sun springs sorting centre, covering more than 60 items and promoting waste reduction. Data-based operations have supported door-to-door recovery operations in 23 provinces and 189 regions with 800 tons of daily recovery, data-driven operational decision-making and optimal resource allocation. Access to municipal carbon-inclusive platforms, such as carbon-beneficial sunlight, where users obtain “carbon credits” through recycling, creating incentives for environmental protection. Iii. A system of association that supports the standardization of profit-making models provides such support as branding authorization, technical training, operational guidance, etc. For example, the association can replicate a mature model of “line-underline recovery-selection sales”. Headquarters assists in site selection, design of door-store images and harmonizes the supply of sorting equipment, metering tools, etc., to reduce the risk of initial input from the allies. Diversified profit-making channels to recover price differentials: reduced cost of recovery through scalable purchases, and profit from sales of recycled resources such as paper and plastics. Value-added services: expand customized recycling programmes for business-level clients (e. G., electricians, manufacturing) to increase single-client value. Policy dividend: seek government subsidies or tax incentives in response to national circular economic policies, such as financial support for green sorting centres in some cities. Iv. Development prospects and challenges to the power industry's market potential promote the surge in box waste and provide a stable source for old shell recycling. The project takes over the market through the “internet+” model, such as the sun spring sorting centre, which is accredited at the national level in less than four years. Technical barriers require continuous investment in technologies such as networking, big data, and optimization of order matching algorithms and logistics dispatch systems to cope with the operational pressures of order growth. Regional expansion strategies have deepened service intensity in the regions covered, such as the sun springs project to create additional sorting warehouses, recycling vehicles and jobs; and rapid penetration through the association model in the blank market, with a scaling effect。
