Green Manufacturing, Eco-Friendly Innovation
Since the national government first introduced the concept of "Green Factory" in 2015, ChangfengNew Materials has been actively committed to building a green factory. Centred on sustainable development, we leverage advanced technology and scientific management to tackle pollution. We are dedicated to pollution prevention, continuous waste reduction, and the delivery of environmentally compliant products, striving for both economic and social benefits.
01
Full Water-Based Factory in Operation
After achieving mass production of full water-based eco synthetic leather, ChangfengNew Materials was officially established in Lishui Economic Development Zone in 2015 through a municipal investment attraction project. We built China’s first full water-based synthetic leather factory covering 50,000 square metres, which commenced production the following year. This marked our new path of high-quality development guided by ecological priority and green growth. We have adopted systematic measures to embed sustainable development throughout our operations, from raw materials to factory production, integrating green manufacturing into daily practice.
02
Active Investment in Energy-Saving Projects
In recent years, Changfeng has invested in various energy-saving projects to promote sustainable development, enhance energy efficiency, optimise resource management, and foster a positive industrial ecosystem.
In 2018, we invested in a 396kWp distributed photovoltaic power generation project, with an annual power output of up to 400,000 kWh. To date, cumulative generation has reached approximately 2.3 million kWh, saving around 90 tonnes of standard coal, 2,400 tonnes of CO2, and 72 tonnes of SO2, significantly contributing to environmental improvement.
To conserve water resources, we have implemented a holistic water system balance optimisation solution and upgraded water-consuming equipment. By introducing advanced cleaning technologies, equipment cleaning has become more efficient, saving approximately 10% of cleaning water annually and improving cleaning efficiency by 20%-25%.
We have also carried out energy-saving optimisation across various production details, such as steam condensate recovery system upgrades, insulation jackets for steam pipeline valves, and energy-efficient modifications to inspection and packaging machinery. These measures have delivered significant energy savings, and we will continue to advance new energy-saving renovation projects in the future.
03
Automated & Intelligent Production
To further enhance overall manufacturing capability and energy efficiency, Changfeng has also developed intelligent workshops. In 2021, we optimised our existing systems and invested in an Energy Control System (ECS) and an Automatic Dosing System (DCS). Together with our existing Enterprise Resource Planning (ERP) and Manufacturing Execution System (MES), these form a complete production execution system for synthetic leather manufacturing, enabling the collection of three key data categories throughout production: "foundation, process, and results." This integrated system allows us to manage every production stage and workflow, allocate resources efficiently and intelligently, and achieve smart, clean, green, and safe production, while also accommodating capacity expansion needs over the next five years.
04
Reduced Wastewater & Exhaust Emissions
As a full water-based synthetic leather factory, we replace organic solvents with water throughout our production processes. We also select raw materials that are recyclable, biodegradable, and free from any hazardous substances. Through continuous process optimisation, we effectively control pollutant emissions at the source. Our production generates only water vapour, along with minimal drying exhaust, printing exhaust, and buffing dust. All wastewater and exhaust gases are collected through gas collection systems and treated before discharge.
05
Green Supply Chain Management
In building our green factory, we enforce strict controls not only on our own hazardous chemicals but also on our raw material suppliers. Changfeng has always adhered to a green procurement policy. To this end, we have established dedicated systems including a green procurement supply chain and standardised procurement procedures, with regular screening and audits of raw material suppliers. Additionally, chemical suppliers are required to register their chemicals on the ZDHC (Zero Discharge of Hazardous Chemicals) gateway, ensuring traceability and control. Raw materials with special requirements must be certified by organisations such as GRS (Global Recycled Standard) and BCI before they can be adopted.
