— 1 — Product characteristics: PET’s advantages are prominentFrom the product perspective, PET bottles have significant advantages in transparency and appearance. Its high transparency enables consumers to see the product clearly, enhancing its appeal. In addition, PET bottles have better design and functionality, and can meet the packaging needs of different products. For example, in the fields of food, cosmetics, condiments, etc., the lightweight and high barrier properties of PET bottles make them an ideal packaging material. In comparison, although HDPE bottles perform well in terms of weather resistance, acid, alkali and salt liquid resistance, they are slightly inferior in terms of transparency and appearance. — 2 — Equipment efficiency: PET has high production efficiency In terms of equipment, PET bottles have h...
The philosophy of plastic is a dialectical meditation on artificial permanence and natural fragility. It is both the cornerstone of modern civilization and a symbol of ecological crisis; it carries mankind’s ambition to control matter and exposes the limitations of technological rationality. In the molecular chains of plastic, there are deep paradoxes of humanity and nature, transience and eternity, creation and destruction . (Image source: earth.com) — 1 — The materiality of plastics: the man-made "second nature" The essence of plastics is the rearrangement of hydrocarbons. By cracking oil and polymerizing molecules, humans have transformed fossil energy that has been dormant underground for hundreds of millions of years into plastic polymers. This process marks the shift of humans from "using nature" to "reconstructing nature" - plastics are no longer tre...
In the global effort to tackle plastic pollution, Design for Recycling has become a widely recognized key technical approach. The core idea behind this concept is to improve product design so that plastic products can smoothly enter the correct recycling and regeneration streams after consumption, and be regenerated into new raw materials. Internationally, North America, Europe, Australia, Singapore, Japan, South Korea, and South Africa have established guidelines or principles for the Design for Recycling of plastic products based on the characteristics of their respective plastic recycling and regeneration systems. China's exploration began in 2019 when the China Plastics Reuse and Recycling Association (CPRRA) first introduced this concept domestically, releasing a series of related standards and initiating the formulation of severa...
Sorting and baling are the first steps in plastics recycling, and provide a basic guarantee for subsequent recycling enterprises. The State Council has issued the "Action Plan for Promoting Large-Scale Equipment Upgrades and Consumer Product Trade-Ins." A wave of construction and renovation of baling stations and sorting centers has swept across the country. State-owned enterprises, capital markets, and leading companies are all getting involved. According to incomplete statistics, there are about 10,000 plastic baling stations and sorting centers in China. However, they generally face challenges such as small scale, scattered distribution, and outdated sorting methods. Strong policy support, sustained demand growth, and continuous innovation in technology and models are driving the construction of baling stations and sorting centers. Their models are constantly evo...
ChinaReplas T&P 2025 The 3rd Plastic Pollution Prevention and Control Theory and Practice Forum Theme: Philosophy of Plastics — 1 — “Prohibition, restriction, substitution” is systematic A symbol of human behavior modification and civilization transformation 1. "Prohibition" : Emergency brakes on out-of-control industrial civilization Metaphor: The ban on the use of certain plastic products (such as disposable straws and plastic bags) symbolizes humanity's denial of the uncontrolled expansion of production and consumption patterns. Industrial civilization once regarded "convenience" and "economic growth" as its norms, but the rampant plastic pollution has exposed the cost of this model - the collapse of the ecosystem and the threat to human health. Deeper meaning: Through the ban, society conveys a clear rejection of "unsusta...
