With the development of society and the growing emphasis on the concept of sustainable development, sustainable design principles have increasingly permeated various product fields. Plastic, commonly used in furniture products, contributes significantly to environmental pollution, not only causing visual pollution but also posing a potential threat to the ecological environment. Building a circular economy and pursuing sustainable development have become global focal points and urgent tasks, and they are starting to guide the development of industries and human activities. As designers, when using plastic materials in furniture product design, it is essential to fully consider the basic requirements of sustainable development. By optimizing material selection, enhancing product structures, and promoting recycling, designers can upgrade and redesign products using waste materials through sustainable design approaches. This helps reduce resource waste, minimize environmental pollution, extend product lifecycles, and promote sustainable development.
