The second working meeting for the formulation and revision of the national standard *Requirements for Production and Sales Management System of Recycled Plastics* was presided over by Wang Yonggang, Secretary-General of the Recycled Plastics Branch of China Material Recycling Association. The meeting brought together industry experts, enterprise representatives and relevant policymakers from across the country to jointly discuss the draft of this national standard.

As an engineering plastic with excellent performance, polycarbonate plays a crucial role in numerous fields such as electronics and electrical appliances, automotive industry, construction, and medical care, relying on its outstanding properties in optics, mechanics, thermology, and chemistry. Although the current industry shows a certain pattern and trend in terms of production capacity and trade, with the continuous progress of science and technology and the continuous evolution of market demand, polycarbonate will continue to develop toward high performance, green manufacturing, circular economy, and expansion of cross-border applications. In the future, polycarbonate is expected to achieve breakthroughs in more fields and make greater contributions to the progress and development of human society.

Analyze the application fields and development trends of polycarbonate from different perspectives.

In the vast field of materials science, engineering plastics have become an indispensable cornerstone of modern industry due to their excellent performance. As an outstanding representative of engineering plastics, polycarbonate (abbreviated as PC) has demonstrated extraordinary value in numerous fields by virtue of its unique molecular structure and superior comprehensive properties. Its presence can be seen from daily electronic products to high-end aerospace equipment. This article will delve into the mysteries of polycarbonate, covering its definition, characteristics, production processes, application fields, industry status quo, and future development trends, presenting the charm and potential of this magical material in an all-round way.

In the nearly hundred years since plastic was invented, the total amount of plastic manufactured by humans has exceeded 10 billion tons. When these materials that once brought convenience to life become mountains of garbage, plastic recycling has evolved from an environmental issue into a survival topic concerning the sustainable development of the earth. Data shows that less than 10% of plastic worldwide is effectively recycled, while about 8 million tons of plastic flow into the ocean every year, forming a shocking "Eighth Continent". Plastic recycling technology is becoming the key to cracking this dilemma.

Against the backdrop of growing global attention to environmental protection and sustainable resource utilization, the plastics industry is undergoing a profound transformation. While traditional plastics have brought convenience, their non-biodegradable nature and high energy consumption in production have triggered serious environmental problems. Environmentally friendly energy-saving plastics have emerged, aiming to reduce environmental pollution and energy consumption, becoming a key force in promoting the green transformation of the plastics industry. The recycling and regeneration of PET waste films in the electronics industry is a significant practice in the development of such plastics, demonstrating a trend that brings new development directions and opportunities to various industries.

Plastic recycling melt filters serve as core equipment in the production of recycled plastics, functioning to remove impurities from molten plastic and ensure the quality and performance of recycled materials.

In an era of resource scarcity and growing environmental awareness, the recycling of plastic waste by enterprises has emerged as a pivotal link in achieving sustainable development. As a widely used material, the disposal of plastic waste has long been a focal point of environmental concerns. By engaging in plastic waste recycling, enterprises not only help alleviate environmental pressures but also tap into new economic growth points, enhancing their social responsibility and market competitiveness.
