Concise design

While ensuring product functionality and performance, reduce the physical dimensions of products to minimize the use of materials; Reduce the techniques such as electroplating, printing, and bronzing, and use texture mapping instead; Simple package design to minimize material use;

Re-use

Greater durability of products; Modular design and component standardization to reduce frequency of structure change;

Recycling

Use recyclable materials and avoid the use of hazardous substances; Use homogenous materials, and mark each type of material and its lifetime to facilitate recycling;
