Due to the ever-increasing amount of electronic waste (e-waste) worldwide, the problem of the effective disposal of printed circuit board waste (WPCB), which are environmentally hazardous, difficult to recycle and economically valuable products, has become a major environmental challenge. Conventional WPCB recycling techniques have low efficiency and require tough processing, such as heat treatment and high pressure. This paper presents a new composite material for the manufacture of printed circuit boards (PCB) that can be easily recycled into their original components and reused. In addition, the most valuable PCB components (electronic components containing precious metals) can be easily separated from the printed circuit board and reused. This study demonstrates the benefit of using biodegradable polymers as binders for PCBs in terms of environmentally friendly and efficient recycling.
由于全球电子废弃物（e-waste）的数量不断增加，印刷电路板废料（WPCB）的有效处理问题成为一个重大的环境挑战。WPCB 是一种对环境有害、难以回收且具有经济价值的产品。传统的 WPCB 回收技术效率低下，需要进行热处理和高压等苛刻的处理。本文提出了一种用于制造印刷电路板（PCB）的新型复合材料，该材料可以很容易地回收成其原始组件并重复使用。此外，还可以很容易地从印刷电路板中分离出最有价值的 PCB 组件（含有贵金属的电子元件）。本研究表明，在环保和高效回收方面，使用可生物降解聚合物作为 PCB 的粘合剂具有优势。
