Project Overview

案例概述

The "Implementation Plan for the Household Waste Classification System" clearly stipulates that "the source classification of household kitchen waste should be strengthened to increase the separation rate and purity." As a national pilot for standardized waste classification, the XinChuan area in the High-tech Zone of Chengdu City is required to take on the responsibility of model innovation and demonstration leadership, break through the bottleneck of the traditional "mainly relying on publicity and low classification efficiency," and explore a sustainable market-oriented governance path. Moreover, the traditional classification model of household kitchen waste relies on residents' voluntary disposal, with a complex process (such as "breaking the bag for disposal"), leading to insufficient participation willingness, a high proportion of kitchen waste mixed with other waste, and great difficulty in subsequent resource utilization and insignificant reduction effects. Against this backdrop, the XinChuan area focuses on the core goal of "source reduction and precise classification" of household kitchen waste, innovatively explores a governance model of "full social participation and market-oriented operation," effectively addressing the pain points of "difficult resident participation, difficult quality and efficiency improvement, and difficult model sustainability" in traditional waste classification work.

《生活垃圾分类制度实施方案》明确要求“强化家庭厨余垃圾源头分类，提高分出率和纯净度”，成都市高新区新川片区作为国家级垃圾分类标准化试点，需承担模式创新与示范引领责任，突破传统 “宣传为主、分类效率低” 的瓶颈，探索可持续的市场化治理路径。此外，家庭厨余垃圾传统分类模式依赖居民自主投放，流程复杂（如“破袋投放”），导致参与意愿不足，厨余垃圾混入其他垃圾比例高，后续资源化利用难度大，减量效果不明显。在此之下，新川片区聚焦家庭厨余垃圾 “源头减量、精准分类” 核心目标，创新探索 “全社会参与、市场化运作”的治理模式，有效破解传统垃圾分类工作中“居民参与难、质效提升难、模式持续难”的痛点问题。

In 2023, the XinChuan area officially implemented the "Double 20-day Work Method" (the first 20 days to build an atmosphere, the second 20 days to improve efficiency), and launched the "bucket exchange" recycling model in 9 pilot communities, establishing a closed-loop system of "residents - property management - professional companies - intelligent terminals." As of August 2025, the pilot covered 7,799 households, with a cumulative recovery of 692.72 tons of kitchen waste and a purity rate of 98%, forming a replicable and scalable "High-tech Zone solution" for the reduction and classification of household kitchen waste, contributing to the green and low-carbon development of the region.

2023年，新川片区正式推行“双 20天工作法”（前20天建氛围、后20 天提质效），在9个试点小区落地“以桶换桶”循环模式，构建“居民 - 物业 - 专业公司 - 智能终端”的闭环体系。截至 2025年8月，试点覆盖 7799 户家庭，累计回收厨余垃圾 692.72 吨，垃圾纯净度达98%，形成可复制、可推广的家庭厨余垃圾减量分类 “高新方案”，助力区域绿色低碳发展。

 Project Outcome

项目成果

First, in terms of environmental benefits, a total of 692.72 tons of kitchen waste was recycled, reducing the amount of such waste entering the landfill process. The purity of kitchen waste reached 98% (exceeding 96% during the pilot period), laying the foundation for subsequent resource utilization and reducing the difficulty of handling mixed waste. According to industry standards, the resource utilization of 692.72 tons of kitchen waste can prevent the generation of methane during landfilling (with the greenhouse effect being 28 times that of CO₂), equivalent to reducing CO₂ emissions by approximately 5,800 tons.

一是在环境效益方面，累计回收厨余垃圾 692.72 吨，减少同等体量垃圾进入填埋环节；厨余垃圾纯净度达 98%（试点期超 96%），为后续资源化利用奠定基础，降低混合垃圾处理难度。按行业标准估算，692.72 吨厨余垃圾资源化利用可避免填埋产生甲烷（温室效应为 CO₂的 28 倍），等效减少 CO₂排放约5800余吨。

Second, in terms of social benefits, through concentrated publicity and on-site guidance, the residents' awareness of the "bucket-to-bucket" model reached 95%, covering approximately 7,000 households. The daily number of small green bins for household kitchen waste collected reached over 500, and the daily amount of household kitchen waste collected and transported was 1.05 tons. This significantly enhanced the participation of the community in green and low-carbon activities and promoted the popularization of the green living concept in the community.

二是在社会效益方面，通过集中宣传与现场引导，居民对 “以桶换桶” 模式知晓率达 95%，覆盖居民约7000余户；日均回收家庭厨余垃圾小绿桶数量达500余个，日均家庭厨余垃圾清运量达1.05吨，显著提升社区绿色低碳参与度，推动社区绿色生活理念普及。

Thirdly, in terms of economic benefits, by adopting the "market-oriented operation" model, the transportation, cleaning, and pre-treatment processes are entrusted to professional entities, resulting in a 30% reduction in costs compared to the traditional model where the government provides full subsidies; the recycling of bucket containers (with each container's lifespan extended to over one year) reduces the costs of purchasing and replacing plastic buckets.

三是在经济效益方面，采用 “市场化运作” 模式，将运输、清洗、预处理等环节交由专业主体，较政府全额补贴的传统模式降低成本 30%；桶具循环使用（单个寿命延长至 1 年以上），减少塑料桶采购与更换成本。

Project Highlights

项目亮点

First, utilize the existing garbage storage points in the community as the transfer points, integrate the existing transportation forces of the property management to undertake the transfer of garbage containers, and no large-scale infrastructure needs to be built, thereby reducing the implementation costs.

一是依托小区现有生活垃圾暂存点作为换桶点位，整合物业现有运输力量承担桶具转运，无需新建大规模基础设施，降低落地成本。

Second, establish an ecological collaborative system of "Party building leadership + professional services + intelligent support + property/enterprise collaboration + residents' participation", achieving full-chain connection of "classification - transportation - treatment - management", breaking the fragmented barriers among various parties in traditional governance, and presenting a tripartite win-win ecosystem where "residents are willing to participate, enterprises are willing to invest, and the government is willing to promote".

二是构建“党建引领 + 专业化服务 + 智能化支撑 + 物业/企业协同 + 居民参与”的生态协同体系，实现“分类 - 运输 - 处理 - 管理”全链条衔接，打破传统治理中各方割裂的壁垒，呈现“居民愿参与、企业愿投入、政府愿推广”的三方共赢生态。

Third, Xinchuan District has been designated as a "national standardized pilot area for garbage classification", and its "bucket-to-bucket" model provides valuable reference experience for similar areas to carry out household kitchen waste management work. Relevant experiences were promoted as typical cases at the Haidian District's garbage classification work conference, and were highly recognized within the region.

三是新川片区被列为“垃圾分类国家级标准化试点区域”，其“以桶换桶”模式为同类区域开展家庭厨余垃圾治理工作提供了宝贵的参考经验，相关经验在高新区垃圾分类工作会议上作为典型案例进行推广，得到了区域内的高度认可。

Project Implementation

项目实施

Based on the "20-Day Dual Work Method" as the core framework, various tasks are systematically advanced from four dimensions: plan formulation, team establishment, atmosphere creation, and model innovation. This ensures the efficient implementation of the "bucket-to-bucket" model for household kitchen waste.

I. Project Implementation Process

一、项目实施过程

(1) Top-level Design: Develop the "Dual 20-Day" Overall Plan

Establish the operational concepts of "innovation-driven, tailored by location, and precise classification", and adopt the "Dual 20-Day Work Method" as the pilot operation overall plan. Among them, the first 20 days are the atmosphere-building period, where a combination of "5 days of concentrated publicity + 15 days of on-site guidance" is adopted to quickly enhance residents' awareness and participation willingness of the "Bucket-to-Bucket" model, creating a strong garbage classification atmosphere; the last 20 days are the quality and efficiency improvement period, focusing on classification accuracy, bucket recycling efficiency, and data traceability capabilities. By using intelligent terminals to monitor the classification situation in real time, continuous optimization of supervision strategies is carried out, continuously consolidating and enhancing the classification effect, ensuring the stable and efficient operation of the "Bucket-to-Bucket" model.

（一）顶层设计：制定 “双 20 天”总方案

确立“创新驱动、因地施策、精准分类”运营理念，并以“双 20天工作法”作为试点运营总方案。其中，前20天为氛围构建期，通过“5天集中宣传 + 15天现场引导”的组合方式，快速提升居民对“以桶换桶”模式的认知度和参与意愿，营造浓厚的垃圾分类氛围；后20天为质效提升期，重点关注分类精准度、桶具循环效率以及数据溯源能力，借助智能终端实时监控分类情况，持续优化督导策略，不断巩固和提升分类效果，确保“以桶换桶”模式稳定高效运行。

(2) Team Support: Establish a "Five-in-One" Work Team

With party building as the core, form a "professional service + intelligent support + community + property management + professional company" five-in-one team; establish a weekly meeting mechanism to clarify responsibilities (front-end staff conducting door-to-door publicity, mid-end professional companies for transportation and pre-processing, back-end for small-scale venous home disposal and cleaning), ensuring a closed-loop of responsibilities for all tasks and promoting them efficiently.

（二）队伍支撑：组建 “五位一体” 工作专班

以党建引领为核心，组建 “专业化服务 + 智能化支撑 + 社区 + 物业 + 专业公司”五位一体队伍；建立周例会机制明确职责（前端工作人员上门宣传、中端专业公司运输预处理、后端小型静脉家园处置清洗），确保各项工作责任闭环，高效推进。

(3) Atmosphere Creation: Break through residents' cognitive barriers in stages

Firstly, a special publicity team was established and a concentrated publicity campaign was carried out over 5 days. The operation process of "bucket-to-bucket" was fully explained to all residents, and the awareness rate of the "bucket-to-bucket" model was rapidly increased to 95%. Subsequently, a professional classification supervisor was assigned at each garbage disposal point in the community, and 15-day on-site guidance work was carried out. Through continuous on-site guidance, the first batch of bucket placement coverage in the pilot community reached 60%. Based on the number of households in some communities, the number of households receiving buckets was adjusted, and ultimately, more than 4,500 households received buckets, with the bucket coverage rate stabilizing at 57.99%.

（三）氛围营造：分阶段突破居民认知壁垒

首先是组建专项宣传队伍，利用5天时间开展集中宣传，全方位普及“以桶换桶”操作流程，使居民对“以桶换桶”模式的知晓率迅速提升至95%。随后，在小区各生活垃圾投放点位安排一名专业分类督导员，开展15天的现场引导工作，通过持续的现场引导，试点小区首批发桶覆盖率达到60%，后续根据部分小区户数调整，最终发桶4500余户，发桶覆盖率稳定在57.99%。

(4) Model Innovation: Implementing the "Bucket-to-Bucket" Closed-loop System

Innovatively establish a four-level "bucket-to-bucket" closed-loop system from the resident end to the property management end, the professional end, and the intelligent end. At the resident end, participating households go to the temporary storage point in the community every day at the designated time to exchange dirty buckets filled with kitchen waste for clean ones. At the property management end, professional companies are responsible for collecting the dirty buckets replaced by residents, completing tasks such as weighing and traceability registration, and then uniformly cleaning and disinfecting the dirty buckets to ensure the recycling of bucket sets and the traceability of data. At the professional end, professional environmental protection companies transport the purified kitchen waste collected from recycling to small-scale sanitary homes for pre-treatment, laying the foundation for subsequent resource utilization and improving resource utilization efficiency. At the intelligent end, the terminal system continuously collects data such as the kitchen waste sorting rate and purity per household, providing data support for precise management and dynamic optimization strategies, ensuring the efficient and orderly operation of the entire "bucket-to-bucket" system.

（四）模式创新：落地 “以桶换桶” 闭环体系

创新性构建“居民端 - 物业端 - 专业端 - 智能端” 四级循环的“以桶换桶” 闭环体系。在居民端，试点家庭每日按照规定时间前往小区暂存点，用装满厨余垃圾的桶更换干净的桶；物业端由专业公司负责回收居民更换的脏桶，完成称重、溯源登记等工作后，对脏桶进行统一清洗消毒，保障桶具的循环使用和数据的可追溯性；专业端由专业环保公司将回收的纯净厨余垃圾清运至小型静脉家园进行预处理，为后续的资源化利用奠定基础，提升资源利用效率；智能端则通过终端系统实时统计每户居民的厨余垃圾分出率、纯净度等数据，为精准管理和动态优化策略提供数据支持，确保整个“以桶换桶”体系高效、有序运行。

 

II. Comparison Before and After Implementation

二、实施前后对比

Before implementation, the challenges were: low participation of residents (complex traditional model process), insufficient classification purity (less than 80%), high cost of manual supervision and difficulty in tracing data.

实施前挑战：居民参与意愿低（传统模式流程繁）、分类纯净度不足 80%、人工督导成本高且数据难溯源。

After implementation, improvements were achieved: The "bucket-to-bucket" model operation received support from the pilot funds and technical guidance of Chengdu High-tech Zone, and community residents and property management actively cooperated, solving the problem of "difficult multi-party collaboration", effectively increasing the participation rate of residents (bucket distribution rate 57.99%), achieving a purity of 98%, and realizing precise management through intelligent terminals.

实施后改善：“以桶换桶”模式运行获成都市高新区试点资金、技术指导等各方面支持，社区居民、物业主动配合，破解“多方协同难”问题，居民参与率有效提升（发桶率 57.99%）、纯净度达98%、智能终端实现精准管理。

Project Impact & Sustainability

项目影响力、可推广性与可持续性

I. Project Impact, Scalability and Sustainability

一、项目影响力、可推广性与可持续性

1. The "20-Day Dual Work Method" has strong adaptability. The first 20 days focus on "awareness - participation", and the last 20 days focus on "quality and efficiency - habits". No large-scale infrastructure renovation is required, and it is suitable for rapid implementation in different scenarios such as old residential areas and newly built residential areas. 一是“双 20 天工作法”适配性强。前 20 天聚焦“认知 - 参与”，后20天聚焦“质效 - 习惯”，无需大规模基础设施改造，适合老旧小区、新建小区等不同场景快速落地。

2. "Bucket-to-Bucket" reduces participation barriers. By replacing "bag-opening disposal" with "bucket exchange", it addresses the core pain point of residents' "disliking the hassle", and the participation rate is more than three times higher than the traditional model.

二是“以桶换桶” 降低参与门槛。通过“换桶”替代“破袋投放”，解决居民“嫌麻烦”的核心痛点，参与率比传统模式提升3倍以上。

3. The "Government-Enterprise-Community" collaborative mechanism is sustainable. The government is responsible for top-level design and supervision, while market entities (property management, professional companies) undertake operational services. The community and residents actively participate, avoiding the problem of high costs and difficulty in sustainability caused by "government taking over".

三是“政企社” 协同机制可持续。政府负责顶层设计与监督，市场主体（物业、专业公司）承担运营服务，社区与居民主动参与，避免“政府包揽”导致的成本高、难持续问题。

4. Data-driven precise management. The intelligent terminal tracks the diversion rate and purity in real time, and can provide "one-on-one" guidance for families with poor classification. Compared with "one-size-fits-all" publicity, the efficiency is improved by 50%.

四是数据驱动精准管理。智能终端实时跟踪分出率、纯净度，可针对分类差的家庭开展“一对一”指导，比“一刀切”宣传效率提升50%。

II. Future Planning

二、未来规划

1. Promote on-site processing of kitchen waste bins. In the future, we will plan to build advanced modular "kitchen waste stations", which are expected to increase the processing efficiency by more than 30%, while reducing energy consumption in the garbage transportation process and further lowering carbon emissions. This will drive the development of household kitchen waste processing towards more efficient and low-carbon directions.

一是推动厨余桶就地处理。未来将规划建设先进的撬装式“厨余驿站”，预计将处理效率提升30%以上，同时减少垃圾运输环节的能耗，进一步降低碳排放，推动家庭厨余垃圾处理向更高效、更低碳的方向发展；

2. Expand intelligent disposal categories. Build an intelligent garbage classification system covering all categories to enhance the overall intelligence level of garbage classification.

二是拓展智能投放品类。构建覆盖全品类的智能垃圾分类体系，提升垃圾分类的整体智能化水平；

3. Expand the model across the entire region. Comprehensively summarize the practical experience and methods of the "bucket-for-bucket" model in the pilot areas to provide standardized guidance documents for the promotion of the model. Transform the successful experience of Xinchuan District into a common practice in the High-tech Zone, and create a "High-tech Zone Garbage Classification Model".

三是模式全域扩面。全面总结试点区域的“以桶换桶”模式实践经验和做法，为模式的推广提供标准化的指导文件，将新川片区的成功经验转化为高新区的普遍实践，打造“高新垃圾分类样板”。
