Project Overview

During the initial operation phase of Qianzishan Park, solid waste treatment units operated in relative isolation. Internal recycling chains for self-generated green electricity, reclaimed process water, and solid waste by-products were not established, leading to low overall resource recovery efficiency. The low-carbon philosophy had not been systematically integrated into the full internal management workflow, and there were no regular codes of conduct or guidance on low-carbon practices for employees and production teams.

External outreach activities were limited to basic business introductions, and the low-carbon demonstration and science communication value of education spaces remained underutilized. Moreover, the park lacked sufficient efforts to advance coordinated carbon reduction with upstream and downstream partners, failing to build joint forces for emission cuts across the industrial chain.

In the early operation stage, stable and compliant production was set as the core objective. The construction of a park-wide resource recycling system was not planned from a holistic systematic perspective. The education space was positioned merely for business display, without immersive and demonstrative content built around low-carbon practice scenarios.

No coordination mechanisms or benefit linkage frameworks for joint carbon reduction with supply chain partners were put in place, resulting in insufficient supporting carriers for emission reduction collaboration between upstream and downstream stakeholders.

Building on the existing operational systems and facilities, the park establishes corporate-level low-carbon governance and resource recycling mechanisms to form closed-loop utilization chains for energy, water and solid waste within the park.

It develops a low-carbon guidance system covering all scenarios including production, office work and daily life to advance the regular implementation of low-carbon concepts. The functions of education spaces are upgraded to create dedicated venues showcasing low-carbon practices.

The park also deepens coordinated carbon reduction across the industrial chain, striving to build a replicable, sustainable and scalable demonstration model for corporate low-carbon practices.

项目背景

园区投运初期，固废处置各单元相对独立运行，自产绿电、生产中水、固废副产物等内部资源循环利用链条未打通，整体资源化效率不高；低碳理念未系统性融入内部管理全流程，员工、生产班组缺乏常态化低碳行为规范与指引；对外宣教仅覆盖基础业务介绍，宣教空间的低碳示范、科普传播价值未充分挖掘；园区与上下游产业链协同减碳力度不足，未形成联动降碳合力。

运营初期以生产稳定达标为核心目标，未从全园区系统视角统筹资源循环体系建设；宣教功能定位偏业务展示，未结合低碳实践场景打造体验化、示范化内容；未建立产业链协同减碳的对接机制与利益联结路径，上下游减碳协同缺乏支撑载体。

立足现有运营体系与设施基础，搭建企业层级低碳治理与资源循环机制，打通园内能源、水资源、固废资源闭环利用链条；构建覆盖生产、办公、生活全场景的低碳行为指引体系，推动低碳理念常态化落地；升级宣教空间功能，打造低碳实践展示阵地；深化产业链协同减碳，建成可落地、可延续、可推广的企业低碳实践示范样板。

 

Project Implementation

Launched officially in May 2022, this project is fully implemented by Wuhan Huantou Qianzishan Environmental Industry Co., Ltd. Relying on the park’s mature production facilities, office buildings, environmental education venues and supporting road networks, the company systematically drives green and low-carbon transformation with targeted solutions to resolve operational bottlenecks from the early park operation phase across five dimensions:

1.Address the lack of top-level systems for low-carbon management: Improve overarching low-carbon institutional frameworks

Taking the park’s full-coverage smart management and control platform as the carrier, the company integrates carbon peaking and carbon neutrality assessment indicators into daily corporate governance to prioritize green-oriented operations. Drawing on its qualification as a National Carbon Emission Standardization Pilot Unit, it carries out regular carbon inventory work and carbon data disclosure, and establishes connections with regional carbon inclusion and emission reduction mechanisms.

The enterprise takes the lead in formulating the group standard Technical Specifications for Zero-Carbon Park Evaluation to standardize and replicate its mature low-carbon management models. Mandatory assessment rules constrain management decision-making, forming a long-term top-down mechanism to advance low-carbon development.

2.Address the imperfect internal resource recycling system of the park: Tap into the recycling value of production lines

All production wastewater undergoes advanced on-site treatment and is 100% reused for equipment cleaning and park greening, saving 180,000 tons of water per year. Steady green power generated by domestic waste incineration is prioritized to supply power for on-site production equipment and office buildings.

New charging piles are additionally deployed to consume surplus green electricity for official vehicles and employees’ private cars, creating a circular model for local consumption of power generated within the park. Technical transformation for resource utilization of kitchen waste liquid has been completed.

Recycled carbon sources are produced via the existing wastewater treatment system, cutting carbon source consumption by 1,440 tons annually and achieving a direct carbon emission reduction of 800 tons, so as to fully unlock the resource recovery potential of solid waste.

3.Address the absence of regular low-carbon office and commuting habits among staff: Upgrade low-carbon office and logistics management

Paperless online approval and virtual meetings are fully implemented to reduce printed documents and foster zero-waste office practices. Electric shuttle buses are deployed within the park; official vehicles and sanitation work vehicles are gradually electrified, while green commuting modes are advocated for all employees.

Special training sessions on energy conservation and carbon reduction are held on a regular basis, and a zero-carbon volunteer service team is set up. Serial ecological culture events are organized on World Environment Day, National Low Carbon Day and National Zero Waste Day to integrate low-carbon behaviors into employees’ daily work and trips.

4.Address weak carbon reduction coordination across the industrial chain: Optimize green supply chain management

New assessment clauses covering environmental qualification, pollutant emission control and recyclable packaging are added to the bidding system, embedding low-carbon requirements at the procurement access stage.

Based on long-term supply chain partnerships, cooperating enterprises are guided to optimize raw material consumption and pollution control. The company has joined the green and low-carbon urban construction industrial alliance initiated by Wuhan Dual-Carbon Industry Research Institute, exploring new approaches to green and low-carbon urban development together with 124 member units.

Restrictions imposed on the procurement side drive the entire industrial chain to improve resource utilization efficiency synchronously, extending the reach of low-carbon management to external partners.

5.Address insufficient external low-carbon influence: Revitalize science popularization venues and expand external communication channels

Display contents inside the 2,200-square-meter energy and environmental education center are upgraded to build immersive interactive popular science scenarios themed on circular economy. The park opens regular study tours for primary and secondary schools, enterprises and public institutions.

A practical education base for ideological and political courses is jointly built with Wuhan University and other universities, receiving more than 10,000 visitors every year. Ecological literary field trips and themed essay contests are organized to record the ecological transformation stories of abandoned mining areas through cultural narratives.

Industrial delegations from Belarus, Kazakhstan, Turkey and other countries are received for on-site research and exchanges, sharing the park’s practical experience in circular economy and carbon reduction worldwide.
