This article reviews the environmental best practices in the PCB industry. The need for printed circuit boards (PCB) waste management is increasingly important. Reasons include curbing public lobbying as well as the potential negative financial implications. Printed circuit board (PCB) recyclers become more competitive and reduce costs by maximizing the benefits of environmental best practices. PCB manufacturing uses many processes that are potentially harmful to the environment. Therefore, the negative impacts of printed circuit boards (PCB) hazardous waste can be significant. However, there are significant opportunities available through the adoption of waste minimization and environmental best practices. This article outlines the advantages of adopting such practices within PCB manufacturing. It also details specific examples of making improvements and savings.

RECYCLING PRINTED CIRCUIT BOARDS (PCB)
Printed circuit board (PCB) recyclers are of significant importance. Recycling printed circuit boards with many components could yield more valuable materials like gold, silver, and platinum. This, therefore, means that recycling PCBs is not only about eliminating printed circuit board (PCB) hazardous waste. The process extracts components affixed to the boards. Recycling PCB recovers approximately 99% of the metals. Recycling PCB helps reduce the depletion of natural resources such as copper. Printed circuit board (PCB) waste management could, therefore, be advantageous to many organizations. Recycling printed circuit boards reduce solid waste, landfill, and land pollution.

ENVIRONMENTAL BEST PRACTICE AND HOW TO RECYCLE PCBs
Printed circuit boards (PCB) waste management has various objectives. The reuse of components has first priority. PCBs form about 3% by weight of the total amount of Waste Electrical and Electronic Equipment (WEEE). Dismantling the printed circuit board (PCB) hazardous waste is essential as well. It is also common to dismantle highly valuable components, PCBs, cables, and engineering plastics. It simplifies the subsequent recovery of materials. Also, the printed circuit board (PCB) recyclers should remove cell batteries and capacitors manually and separately disposed of appropriately. The PCBs go to a facility for further dismantling for reuse or reclamation of electric components.
