Research on Green Circulation System of Packaging Engineering Based on Circular Economy Model (Part Two)

3. Packaging cycle principle and packaging engineering green circulation system

The "3R" principle of circular economy refers to the principle of reduction, reuse, and recycling. It requires less input of raw materials and energy to achieve the intended production purpose or consumption purpose, and pay attention to the source of economic activities. Conserve resources and reduce pollution; require that manufactured products and packaging containers be used repeatedly in their initial form, and that the produced goods can be turned into usable resources after they have completed their functions, instead of irreversible garbage. The negative impact of packaging on the environment is mainly due to packaging materials and the resulting packaging waste and packaging container structure. In the circular economy mode, packaging follows the "4R+1D" principle: 4R means: Reduce (reduction) - that is, to meet the packaging of the various functional conditions, the pursuit of simple and simple rather than luxurious waste, so as to achieve waste reduction The purpose of the emissions; Reuse (reusable, effective use) - packaging containers can be used repeatedly in the initial form, requiring resistance to the proliferation of disposable packaging products in the world today, producers should regard packaging as a daily life appliance Designed to be used like tableware and backpacks. It also requires that packaging manufacturers should try to extend the use of the packaging as much as possible, instead of updating it very quickly.

Recycle (recycled product, ie recycled) - that is, packaging waste is recycled to produce new products of the same type, such as recycled paper, renewable cans. Recover (incineration does not pollute the atmosphere and energy is regenerated) is converted into heat by incineration and recycled by landfill treatment. 1D (Degradable) refers to the use of biodegradable technologies to process packaging without causing environmental pollution. Figure 1 shows the framework of a green recycling system for packaging projects.

4. Implementation of Green Circulation System for Packaging Project

The green circulatory system of packaging engineering is a wide range of systematic projects involving packaging manufacturers, commodity circulation and consumption. To this end, we must vigorously promote people's understanding and understanding of the green circulatory system of packaging projects, and interpret the packaging circulatory system model from various perspectives. , need to pay attention to the following points:

4.1 The green design of packaging is the starting point for the green circulation system of packaging engineering

Green design, also known as eco-design, environment-oriented design, etc., refers to the use of various advanced technologies such as concurrent design and other advanced design theories in order to use the product-related technologies, environmental coordination, and economic information in the product life cycle. A system design method with advanced technology, good environmental coordination, and reasonable economy. The packaging green design expands the life cycle of the packaging from the preparation of raw materials to the recycling and reuse of packaging. Figure 2 depicts the entire life cycle of the package. Packaging design is a comprehensive discipline with strong originality. It is the forerunner of packaging engineering circulatory system. Excellent product packaging design is the perfect combination of science and technology and culture and art. There is no ecological design for packaging. The realization of packaging engineering circulatory system can only be A slogan cannot be turned into reality.

4.2 Green Consumption is the Power to Promote the Development of Packaging Green Circulation System

Green consumption includes a wide range of content, including not only green products, but also the recycling of packaging, the effective use of energy, and social supervision. The emphasis is on "green living, environmental protection purchase" and other issues that are directly related to consumer safety and health. Advocating green consumption, promoting the development of packaging recycling economy is inseparable from the concept of green consumption, advocating consumers to pay attention to the disposal of packaging waste in the consumption process, to avoid causing environmental pollution. The focus of social supervision is on the reuse and regeneration of packaging waste, and encourage consumers to sort and store packaging waste in order to protect “green” as a starting point. Opposing comparisons and showing off flashy consumption, oppose over-packaging.

4.3 Establishing sound packaging regulations is the fundamental guarantee for the establishment of a green recycling system for packaging projects

In a situation where the awareness of the harmonious development of man and nature has not yet been fully popularized, it is necessary to strengthen the packaging legislation and establish and improve sound packaging laws and regulations as a compulsory measure to effectively promote the establishment and development of the packaging engineering recycling system. Through legislation, all government decrees and measures are enforceable, and package producers and consumers clearly define their respective responsibilities and obligations. For example, Japanese laws have established specific packaging regulations such as the Waste Disposal and Cleaning Act, the Food Recycling Law, and the Recycling Use of Containers and Packaging Materials Law, which stipulate the production responsibilities and recovery obligations of waste generators and determine wastes. The priority of treatment, that is, waste reduction in the production process → reuse → recycling → heat recovery → safe disposal principles.

In accordance with the relevant provisions of the "Law of the People's Republic of China on the Prevention and Control of Environmental Pollution Caused by Solid Wastes," China formulated the "Provisional Management Measures for the Recycling of Packaging Resources," which stipulates the management principles for the recycling of packaging wastes such as paper, wood, plastics, metals, and glass. Recycling channels, etc., are a good start for packaging legislation. However, the absence of food packaging regulations has caused obstacles in the recycling of packaging. Therefore, packaging regulations need to be further improved and refined. According to the experience of developed countries, the law of recycling of resources was established from the management of waste, and the basic law of circular economy was formulated.

4.4 Cleaner production is the key to the sustainable development of the packaging industry

Cleaner production requires the continuous implementation of comprehensive preventive measures for the products and their processes. It requires that, while increasing production efficiency, both the reduction or elimination of the use of hazardous wastes and other toxic chemicals must be taken into account, and the working conditions should be improved to reduce the health threats to operators. , And can produce safe and environmentally compatible products. Although the initial focus of packaging cleaner production is to prevent the pollution of packaging waste, its connotation includes the recycling of packaging waste at different levels. It also includes reducing the use of toxic and hazardous packaging raw materials and reducing packaging waste and pollutants. Generation and discharge, so that the packaging, installations, production lines are using clean production programs, packaging companies to implement cleaner production is the cornerstone of packaging recycling economy, packaging cycle economy is the expansion of packaging enterprise production. The implementation of clean production and packaging circular economy of packaging companies is the only choice to overcome the bottleneck of sustainable development of packaging enterprises in China.

5 Conclusion

The packaging engineering system is not only controlled by people's consumption consciousness, but also by the natural environment. The only solution to the harmonious coexistence of people and products and the environment is to enable the packaging engineering system to imitate the structural principles and operating rules of the ecosystem to a certain extent, and ultimately realize the ecologicalization of the green recycling system and packaging economy of the packaging project, and gradually establish "Packaging green circulation mode".
