Product packaging environmental design to achieve: circular economy

Change the input method of raw materials, use them locally, reuse the valuable products and recycled products, recycle various materials during the process, change production technology or manufacturing technology, improve process control, and transform existing equipment. Consumption of raw materials, generation of waste, energy consumption, health and safety risks, and damage to ecology are minimized; the use of the natural environment is as far as possible, and environmental assessments of air, soil, water, and waste discharges are conducted, based on relative environmental load. Scale to determine its impact on biodiversity, human health and natural resources.

Recycling and environmental protection design, it is a kind of packaging material in the initial stage of the design will consider the possibility of recycling of packaging materials, recycling value, recycling methods and a series of issues, so as to achieve the maximum use of packaging materials, energy, and the environment The least polluting design ideas and methods. Recyclable design includes: recyclable materials and signs, recyclable processes and methods, economic evaluation of recyclability, recyclable structural design, and more. At present, many countries in the world are using direct recycling technology to collect, sort, crush, clean, melt, or directly shape plastic bottles. In order to improve the classification efficiency, the United States developed a plastic bottle automatic delivery system that uses a computer-controlled mechanical device and a fluorescence sensor to automatically detect PET bottles from mixed bottles of PVC and PET and remove them from the conveyor belt. Environmentalists in China pointed out that the main culprit of “white pollution” is not the lunch boxes and plastic bags themselves, but they are not well recycled. Now some cities in our country have also proposed that whoever produces a disposable lunch box who is responsible for recycling, and has formulated a reward and punishment policy for recycling, which has played a good effect. Some other cities have reclaimed waste plastic packaging into renewable plastics through conversion and recycling technologies for reuse or developed waste plastics refining technologies, which have been well received by the industry. At present, the Chinese government has invested heavily in the planning and construction of garbage collection, sub-refinery and power generation projects, which are of great significance for protecting the ecological environment and sustainable development.
