Keywords sustainable development green design life cycle recycling

The deterioration of the global ecological environment poses a great threat to human survival. The depletion of natural resources poses a serious challenge to the development of human society. All these major issues on the survival and future of humankind have caused more and more people of insight to worry and think. The strategy for sustainable development that came into being clearly pointed out that in the process of human development, people are the main body and economy is the foundation. Maintaining a reasonable total amount of resources and maintaining a good ecological environment are prerequisites for development; it also emphasizes that economic development is not only To meet the needs of the present generation, we must also protect and use the natural environment and resources on which humankind lives, and create conditions for the sustainable development of future generations.

Green design is the embodiment of sustainable development in the industrial field. This article tries to improve people's awareness of environmental protection through the analysis of green design and its guiding automotive recycling industry, popularize the strategic thinking of sustainable development, and explore ways for effective, comprehensive, and recycling natural resources.

Traditional product design

1.2 The openness of traditional product design cannot comply with the requirements of environmental protection

Due to the open-loop nature of the traditional product life cycle, for a long time, although this open-loop operation model has promoted the development of society, its open-loop development has brought about a heavy cost of destroying the ecological environment and accelerating resource depletion. In exchange. With the rapid development of modern science and technology and economy, traditional product design has completely failed to comply with the requirements of social development and environmental protection. Considering the product's full life cycle design, green design has become a wise choice.

2. Green design

Green design is also called ecological design or product life cycle design. Green design is based on the traditional product design and innovation. Products made with green designs not only meet user needs and corporate profits, but also strive to minimize negative environmental and resource impacts throughout their life cycle. The green design pursues the environmental, functional, and economical unity of the product. That is, the green design product must have both a high performance-to-price ratio and a performance-environmental load ratio. This shows that the green design is designed to protect the environment. .

2.1 Product-oriented life cycle of green design

Green design takes the degree of greenness of a product as one of the important design goals and runs through the entire life cycle of the product. The theme of green design is green thinking. In the product design phase, the green thinking will fully consider the ease of assembly and disassembly of the product structure, maintainability, reusability, and continuous applicability of the product (ie, by designing component replaceability, easy to implement product upgrades, and maintaining continuous function Applicability) etc. In the selection of materials, the green thinking will fully consider the use of materials that are harmless to the environment and human body; avoid the use of depletion or rare materials; try to use recycled and renewable, environmentally degradable raw materials. At the stage of product manufacture, use, and recycling, Green Thinking will minimize the environmental pollution of product packaging materials, comprehensively control the waste generated during product manufacturing process, reduce the pollution to the environment, establish a product after-sale maintenance service network and recycle waste products. system. This whole process of product design begins with the end of product recycling and re-starting, which shows the product-oriented full life cycle of green design.

2.2 The full range of green design

The unique omni-directional and multi-level nature of green design is one of the important differences between it and traditional product design. Its main performance is in the following aspects:

2.2.1 Governance Technology and Product Design

Green design is based on the original product design, adding recyclability design, detachable design, reusability design and so on. In this way, the products designed not only meet the needs of users, but also create conditions for the recycling and recycling of waste products in advance.

2.2.2 Clean Prevention Technology and Green Design

The purpose of the green design is to minimize the environmental pollution caused by the product at various stages of the life cycle; for example, to reduce the exhaust pollution of motor vehicles, to promote less non-cutting processes, and to reduce the generation of waste in the manufacturing process.

2.2.3 Design to increase the total value of the product

Traditional product costs include only manufacturing costs, sales costs and profits. The cost of green products includes not only the above costs, but also the cost of the environmental responsibility of the product after its use and disposal, and the cost of recovering the environment and resources. Therefore, improving the total value of products can more truly reflect the product's eco-efficiency in the entire life cycle such as design, manufacture, sales, use, and post-treatment disposal.

2.3 Green design changes open-loop operation mode to green closed-loop operation mode

"Abandonment of resources" is an inevitable and objective phenomenon in human social activities. However, in the green design, the "recycling of waste" is not only feasible, but also particularly necessary. The so-called "product disposal" is only from the aspect of product function. If decomposing waste products into smaller units, such as parts or modules, then they are valuable resources that are very valuable! As long as we adopt a scientific method and find a way for them to recycle, it will be of great significance to the development of enterprises, environmental protection, and resource conservation.

In this way, the existing resources can be recycled more economically, efficiently, and conveniently. This will greatly reduce the demand for natural resources and damage to the ecological environment during the production of industrial products. It can be seen that the green design not only extends the life cycle of traditional products, but also changes the open-loop operation into closed-loop operation.

2.3.2 Sustainability of Green Design

Due to the unique closed loop nature of green design, green design is sustainable. The green design throughout the product is always the entire process from the selection of raw materials to the use or even disposal of the product. After “disposal and recycling”, some parts can even undergo a planned “open loop”, that is, they are recycled into another product system for use. For example, there are many parts and components on recycled cars that are quite intact, such as engines, transmissions, steering mechanisms, lighting and electrical equipment, bearings, and other standard parts. After a formal inspection, qualified persons can enter the use of lower-level vehicles or equipment. Such as agricultural power machinery, agricultural vehicles, irrigation and drainage equipment and so on. Obviously, this opens up new areas for the full and effective use of resources.

Recycling design for disassembly is one of the main contents of green design, and it is a concrete expression of sustainable development strategy. From the viewpoint of sustainable development and environmental protection, green design adopts a “resource recovery strategy” in the “use after-use recycling” link in the life cycle. In the product design process, targeted recycling and processing are considered, and it is often possible to achieve more with less. Effect. "Resource recovery strategy" is a design strategy for resource regeneration. Product development should focus on the recycling of waste, that is, on the product and packaging design, emphasize the environmental protection of component parts, the disassembly and orientation of assembly operations, and the miniaturization of parts specifications.
