In today's global economy, developed nations emphasize a comprehensive life cycle assessment (LCA) of products to evaluate their impact on resources, energy use, and the environment throughout all stages—from raw material extraction to disposal. This approach helps shape industrial policies, technological strategies, and product designs, ensuring sustainable economic growth while minimizing environmental harm. LCA has become a crucial tool for identifying areas where improvements can be made, enabling industries to make informed decisions that align with long-term ecological goals.
Plastic packaging materials have proven to be more efficient than traditional alternatives in terms of energy savings, resource conservation, waste reduction, and lower environmental impact. Their lightweight nature and durability make them ideal for modern packaging needs. As society becomes more environmentally conscious, plastic materials are seen as a symbol of technological advancement and progress. However, as environmental concerns grow and resource scarcity becomes more pressing, the future of plastic packaging remains both promising and challenging.
According to partial data, China produces a significant amount of plastic packaging waste, with over 15 million tons of plastic products manufactured annually. Approximately 26% of this is used for packaging, amounting to more than 3 million tons, with a large portion being single-use plastics. These materials are difficult to recycle due to their widespread use, low value, and scattered distribution, leading to serious pollution issues. In major Chinese cities, the proportion of plastic waste in municipal solid waste (MSW) continues to rise, highlighting the growing environmental burden.
For example, in Beijing, daily garbage production is around 12,000 tons, with plastic making up about 3%. In Shanghai, the daily output is around 15,000 tons, and plastic accounts for roughly 7%. Among these, polystyrene (EPS) food containers and ultra-thin plastic bags—commonly found in markets—are major contributors to environmental pollution, often referred to as “white pollution†because of their visual impact and persistence in the environment.
To address these issues, the Chinese government introduced the "Solid Waste Disposal Law" in 1996, mandating that plastic films and disposable products be easily recyclable or biodegradable. The Ministry of Railways was among the first to ban EPS tableware, followed by the Ministry of Communications, which imposed a nationwide ban on such products on Yangtze River and Taihu Lake cruise ships. Several cities, including Beijing, Guangzhou, and Dalian, also implemented local bans on EPS tableware and plastic bags.
In response, China’s plastics and packaging industries have taken proactive steps. Organizations such as the Plastic Recycling Professional Committee and the Foam Plastics Professional Committee have been established to promote recycling and develop eco-friendly alternatives. Additionally, research initiatives like the Degradable Plastics Research Association aim to advance biodegradable materials and improve waste management practices.
The government has also prioritized plastic recycling and degradable plastics in national science and technology plans, integrating research, education, and industry efforts to find sustainable solutions. While the plastic packaging industry is rapidly expanding—outpacing traditional materials in growth—it faces ongoing public perception challenges. Many still hold misconceptions about its environmental impact.
To address these issues, it is essential to recognize the real benefits of plastic packaging, such as its efficiency and cost-effectiveness. At the same time, it is crucial to acknowledge the problems caused by improper disposal of single-use plastics. By raising awareness and implementing stronger regulations, the industry can move toward a more sustainable future, balancing innovation with environmental responsibility.
