I. Concept Innovation: From Extensive Traditional Production to Green Sustainability

In the past, the printing industry prioritized production capacity expansion, efficiency optimization and finished product quality while ignoring environmental losses throughout the production process. Traditional printing relies on highly polluting inks and chemical plate-making materials, generating a large amount of volatile organic compounds (VOCs), wastewater, waste plates, paper scraps and other pollutants. It consumes massive water and electric energy and imposes burdens on the air, soil and water environments. With the implementation of national policies including the Emission Standard of Air Pollutants for Printing Industry and the Guidelines for Green Design of Industrial Products, as well as the rising public awareness of environmental protection, the printing industry has completely abandoned the development model of "prioritizing production over environmental protection". The full-life-cycle green development concept has become a universal consensus across the industry.

The core of sustainable printing lies in adhering to the principles of "source reduction, process management and terminal recycling". It integrates environmental protection concepts into the entire industrial chain including raw material procurement, production and processing, product application and waste recycling. The industry meets market printing demands with minimal environmental impact, realizing a dynamic balance between industrial development and ecological protection. It is not only an inevitable requirement for the industry to respond to the dual-carbon goals and fulfill social responsibilities, but also a core competitiveness for printing enterprises to break through development bottlenecks and achieve high-quality growth. At present, greenization, digitalization, intelligence and integration have become the four core directions for the high-quality development of the printing industry.

II. Source Control: Green Consumables Underpin Environmental Protection

Materials are the foundation of printing production and the first line of defense for sustainable development. Traditional oil-based inks contain a large number of organic solvents and release harmful gases during production and drying, serving as one of the main pollution sources in the printing industry. Modern green printing has fully promoted the transformation "from oil to water", and widely adopted water-based inks, soybean inks and plant-based eco-friendly inks. Taking water and plant extracts as solvents, these inks are free of benzene, formaldehyde and other harmful substances, with drastically reduced VOCs emissions and no pungent odor. They not only ensure a safe production environment, but also eliminate secondary pollution to human bodies and the ecological environment from finished products, making them widely applicable in food packaging, children’s books, cultural and creative products and other scenarios.

The green reform of the industry has continued to deepen in the selection of paper and printing plates. Enterprises give priority to adopting FSC forest-certified paper, recycled waste paper, straw environmental protection paper and other recyclable materials to reduce the consumption of virgin pulp and protect forest resources. Meanwhile, new environmentally friendly plate-making materials without developing processes have fully replaced traditional plates, eliminating developing, fixing, water washing and other procedures. This completely avoids the discharge of strong alkali and heavy metal wastewater from traditional production, reducing more than 80% of production wastewater and realizing pollution reduction from the source. The iteration of green consumables lays a solid foundation for the implementation of green printing.

III. Process Upgrading: Intelligent Technology Empowers Low-Carbon Production

While green consumables form the foundation, process innovation and technological breakthroughs act as the core driving force for the sustainable development of the printing industry. Supported by digital and intelligent technologies, modern printing has completely subverted the traditional high-consumption and high-emission production mode, achieving four major breakthroughs in energy saving, consumption reduction, pollution reduction and efficiency improvement.

On the one hand, new processes such as waterless printing, flexographic printing and nano green printing have been gradually popularized. In particular, nano green printing technology has realized disruptive process innovation, transforming the traditional subtractive etching process into an additive printing process. It requires no chemical corrosion or extensive water washing, producing no waste liquid or waste materials throughout the process, greatly reducing energy consumption and completely solving the pollution problems in plate-making. Featuring low energy consumption, low emission and strong adaptability, flexographic printing has become a mainstream green process in the packaging printing industry, conforming to the environmental protection trend of lightweight and minimalist design.

On the other hand, the industry has comprehensively promoted intelligent production transformation. The application of intelligent typesetting, digital quick printing and precise ink control systems effectively reduces paper waste, consumable loss and product defect rates. In addition, new waste gas treatment technologies including fungal-bacterial mixed biofilters have been applied, greatly reducing VOCs governance costs and improving treatment efficiency to achieve up-to-standard and efficient waste gas purification. Furthermore, enterprises have continuously reduced water and power consumption and built a low-carbon production system through upgrading energy-saving equipment, utilizing photovoltaic power and recycling production wastewater.

IV. Circular Empowerment: Building a Full-Chain Sustainable Ecosystem

Sustainable printing is not limited to emission reduction and carbon reduction in production links, but focuses on building a closed-loop circular industrial ecosystem. Currently, the printing industry actively practices the circular economy concept and builds a complete industrial chain of "production – recycling – regeneration – reuse" to maximize resource utilization efficiency. On the production side, enterprises conduct unified recycling and classified treatment of paper scraps, waste plates, discarded ink barrels and packaging auxiliary materials, and renewable consumables are reprocessed and put into production again. On the terminal side, the industry vigorously promotes minimalist printing and lightweight packaging, abandons excessive binding and redundant packaging to reduce resource waste, and advocates green consumption concepts.

Meanwhile, the industry has continuously improved the green certification system. Green printing enterprise certification, product environmental testing and Life Cycle Assessment (LCA) have become industry standards, forcing the standardized and green development of the entire industrial chain. By optimizing the whole process from renewable raw material utilization and production energy conservation to terminal green output and waste recycling, the industry has fully opened up the green development path, helping the printing industry get rid of the label of "high consumption and high emission" and realize the unification of economic, ecological and social benefits.
