Plastics bring convenience to human life. Before the invention of plastics, the main materials used by humans came from nature, such as wood, stone, cotton, hemp, wool, leather, silk, etc. In "Plastic: Poisonous Love Story" The book mentions: "Plastic is a material utopia, everyone can enjoy" and "cheap to the lack of soul." Because of the "good" plastic: compared with metal materials, the material is lighter, easier to process and cheaper, resulting in the "bad" of plastic: abuse and garbage.
About 400 million tons of plastics are produced every year around the world, of which plastic packaging is the largest application, accounting for 36% of all plastic applications. Because plastic packaging is designed for one-time use, it is one of the most important sources of waste worldwide when it is used up. The problem of plastic packaging waste management needs our attention.
The new plastics economy: Rethinking the future of plastics, presented by Ellen MacArthur Foundation and McKinsey & Company, said that the application of the circular economy principle to the global plastic packaging process will change the material economy, especially to avoid plastic waste. In the natural environment, reducing the negative impacts of plastic waste is important for the environment.
In the Linear Economy model, “resources” are consumables, and many resources lose their utility when used only once, resulting in a waste of resource value. Under the concept of Circular Economy, resource utilization has been rethought. The ideal state of the future industry will not have real waste, because the waste of industry A will become the energy of B industry and maximize the value of resources.
The circular economy principle proposed by Ellen MacArthur Foundation:
The Taiwan Circular Economies Foundation has organized the concept of five major circular economies:
The application of plastics in industrial economy and daily life has become an indispensable material, creating social economic development and the convenience of life. According to statistics, only 9% of the world's plastic waste has been recycled, and plastic waste is improperly managed. About 8 million tons of plastic waste enters the ocean every year. Plastics from human life helpers become the killers of environmental damage. Estimating the circular economy through the Ellen MacArthur Foundation will generate an economic opportunity worth $706 billion, a significant proportion of which comes from plastic packaging. Plastic recycling can reduce the environmental impact of plastic waste and save material and resources. The relationship between plastics and society needs to be re-adjusted. The five concepts of circular economy rethink the future of plastics. The future of sustainable development requires individuals, society, government, enterprises and industries to face and cooperate together to reach the goal of reduce plastic waste.
