Project Overview

China's dual-carbon strategy has been fully implemented. The industrial sector—particularly the fine chemical industry, which represents a key area for energy consumption and carbon emissions—faces significant practical pressures to achieve industrial green transformation, enhance energy efficiency, and control and reduce carbon emissions. Policies such as the "Implementation Plan for Achieving Carbon Peaking in the Industrial Sector" are continuously driving chemical enterprises to accelerate the transformation of their production models, compelling them to integrate production and operations with energy conservation and carbon reduction efforts, and to pursue a development path characterized by high-end, green, and low-carbon growth.

China Energy Conservation Wanrun, as a central state-owned enterprise specializing in new materials under the China Energy Conservation Group, bears both the social responsibility of a state-owned enterprise and the emission reduction obligations of a chemical manufacturing firm. It is tasked with driving independent innovation in the new materials industry while also complying with the green and low-carbon performance assessment requirements imposed by the state-owned capital system. The fine chemical synthesis process involves numerous steps and exhibits high energy consumption intensity; therefore, as the company expands its production capacity and ensures supply stability across its industrial chain, it faces multiple challenges, including energy consumption management, carbon emission control, and resource recycling.

In response to policy constraints, industry transformation, and ESG development requirements, the company leverages its distinctive industrial positioning to integrate the dual carbon goals into its overall corporate development strategy. Building on its technological strengths in environmental protection materials, the company not only empowers downstream industries to reduce their carbon footprint through its products but also proactively implements internal energy efficiency upgrades, optimizes its energy mix, and promotes resource recycling. By advancing the development of green factories and treating green carbon reduction as a core driver for its high-quality growth strategy, the company has embarked on a comprehensive journey of green and low-carbon practice exploration.

Project Implementation

Aligned with the dual carbon goals, this project addresses key pain points across various stages of the fine chemical production process through a systematic approach spanning seven dimensions—management, energy, energy efficiency, circular economy, infrastructure, supply chain, and digital transformation—as detailed below:

To address the absence of a robust carbon emission management system and inadequate response mechanisms, the company has established a Lean Carbon Emission Management System. This system is overseen by the Company's Dual Carbon Work Leading Group (led by the Chairman and the General Manager), with the Engineering and Environmental Protection Department coordinating the deployment of responsibilities across all departments.

The company has formed a dedicated leading group and appointed specialized personnel to develop carbon emission control procedures, set phased targets – achieving carbon peaking by 2030 and carbon neutrality by 2060 – and complete annual official carbon accounting, carbon inventorying for subsidiaries, and carbon footprint calculations for key products. Additionally, the company systematically identifies climate-related risks and opportunities and integrates them into its management and control action plan.

To address the low share of non-fossil energy sources and the dominance of fossil fuels in the company's energy mix, the company is promoting the substitution of non-fossil energy sources, a initiative implemented by the Equipment Department. The company has installed a 771.68 kWp distributed photovoltaic system on idle factory rooftops, which generates 862,500 kWh of electricity annually and operates under the principle of "self-consumption with surplus electricity fed into the grid."

Additionally, the company purchases 3,000,000 kWh of green electricity each month—accounting for over 20% of its total electricity consumption—thereby continuously optimizing its energy mix.

To address energy efficiency challenges—including low equipment efficiency, inadequate system automation, waste of residual heat, and high peak power loads—the company has been steadily advancing energy-saving technological upgrades, led by the Energy System Task Force and implemented by the Equipment Department and the Production Department.

The company continues to execute a phase-out plan for high-energy-consumption equipment, replacing it with Class I or Class II energy-efficient equipment; sensor and interlock devices have been installed in the utility systems to enable automated start-stop control; a peak-shaving and valley-filling cooling storage retrofit has been implemented, utilizing a 1,700 m³ firewater storage tank for load balancing; the use of high-pressure water jet cleaning has replaced conventional atmospheric pressure flushing, resulting in water savings of over 60%; and the combination of electrodialysis membranes with MVR concentration technology has reduced the energy consumption per ton of treated wastewater by more than 60%.

To address the inadequate resource recovery and utilization of waste materials, residual heat, and wastewater, the company has established a circular operating system driven by the collaborative efforts of the Equipment Department, Production Department, Technical Department, and Engineering and Environmental Protection Department. The company recovers waste organic solvents through condensation processes, achieving a recovery rate of 80%–95%; these recovered solvents are then distilled and used as fuel to generate steam, with an annual recovery volume of nearly 6,000 tons.

Leveraging heat pump technology, plate heat exchangers, and air preheaters, the company recovers residual heat from distributed circulating water systems and high-temperature flue gas streams, supplying this heat to various applications—including boiler makeup water supply, hot water storage tanks, heating systems, and flashing apparatus—thereby reducing heat discharge from cooling towers and high-temperature flue gas emissions, as well as lowering steam consumption, resulting in an annual steam savings of 31,260 tons. Additionally, concentrated wastewater and steam condensate are reused, with an annual reuse volume of 230,000 tons.

To address the low level of green transformation in infrastructure sectors such as construction and transportation, the company has established a Green Factory System, implemented by the Engineering Environmental Protection Department and the Service Center. The company utilizes its own green silicate-aluminate building materials to reduce the use of single-use materials; it optimizes natural lighting and ventilation in buildings while installing sensor-activated lighting systems; it has phased out diesel forklifts and deployed 26 electric forklifts; and it has switched to electric vehicles for commuting between factory sites, thereby reducing carbon emissions at the infrastructure level.

To address the issues of packaging waste within the supply chain and overly simplistic end-to-end supply chain management practices, the company has established a sustainable green supply chain, with implementation driven by the Procurement Department, Logistics Department, and Information Department. The company prioritizes the use of large-scale packaging and localized procurement, while promoting the adoption of reusable packaging and metal pallets – resulting in annual savings of over 120,000 packaging units – and has implemented a Warehouse Material Management System to enable comprehensive QR code-based tracking and control throughout the entire supply chain, from raw material receipt to finished product dispatch.

To address the challenges of low manual control accuracy and the imbalance between energy consumption and operational efficiency, the company has leveraged digital and intelligent technologies for system upgrade and enhancement, with implementation carried out by the Technology Department, Production Department, and Information Department. The company is advancing the upgrade of its process automation systems to enable automatic material feeding and temperature control interlocks; it has replaced manual temperature control with a TCU temperature control system and uses the DCS system to manage production parameters; additionally, an Energy Management System has been established to monitor various energy consumption indicators in real time.

Project Outcome

The implementation of this project has achieved a systematic breakthrough in green carbon reduction for the fine chemical industry, yielding multiple quantifiable and replicable innovative outcomes; the key highlights are as follows:

First, the innovation of a management and control mechanism has enabled the company to make a transformative leap from having no established system to implementing comprehensive, lean-based carbon management across the entire operational process. Prior to implementation, the company faced challenges such as an unclear baseline for carbon emissions, dispersed responsibility allocation, and inadequate risk mitigation measures;

However, it has now established a comprehensive carbon emissions management system comprising a "high-level leadership group + dedicated personnel and roles + standardized procedures." The company has clearly defined its three-phase carbon reduction targets spanning the period from 2025 to 2060, significantly enhancing its carbon management efficiency and compliance capabilities, thereby filling the gap in implementing a full-chain carbon management framework within the fine chemical industry.

Second, the integrated innovation of energy efficiency technologies enables a transition from extensive energy consumption to a significant improvement in overall system energy efficiency. Prior to implementation, the equipment exhibited low energy efficiency, inefficient direct discharge of waste heat, and high peak power load pressures; however, through an integrated technological upgrade combining "green power substitution + waste heat recovery + peak shaving and valley filling + equipment upgrading," annual savings of 7,694 tons of standard coal were achieved, and carbon dioxide emissions were reduced by approximately 19,181 tons.

Third, innovative circular economy models have been adopted, transitioning from end-of-pipe treatment to a comprehensive, end-to-end resource recycling system. Previously, waste solvents, wastewater, and residual heat were often simply treated and discharged; however, a closed-loop recycling system covering "materials – solvents – residual heat – wastewater" has now been established. The recovery rate of waste organic solvents ranges from 80% to 95%, with nearly 6,000 tons of waste solvents recovered annually and over 50,000 tons of steam generated – representing a 15% reduction in carbon emissions compared to traditional coal-fired steam generation methods. The annual water reuse volume amounts to 230,000 tons, achieving synergistic benefits in both the resource utilization of by-products and energy conservation and carbon reduction.

Fourth, digital empowerment drives innovation, facilitating the transition from manual management to intelligent, lean operations. The production side has evolved from a model primarily reliant on manual operations to a fully automated end-to-end process, resulting in a 40% increase in per-warehouse production capacity and a 24.7% reduction in production costs; energy management now enables real-time online monitoring of energy consumption across multiple product categories, significantly enhancing both control accuracy and response efficiency.

This project boasts strong sustainability and replicability: it has established a long-term operational mechanism encompassing annual target decomposition, energy-saving technological upgrades, and carbon accounting, with dedicated Carbon Dioxide Peaking and Carbon Neutrality Special Funds providing continuous financial support; its carbon reduction pathway—comprising "Management System + Technological Upgrades + Circular Operations + Digital Empowerment" —is tailored to the production characteristics of the fine chemical industry and can be directly replicated and scaled up across similar chemical manufacturing enterprises.
