Printed circuit board recycling process and its environmental impact assessment

摘要: As the foundation for almost all electronic products, printed circuit board (PCB) recycling issue has received much attention from government, enterprises, and communities. In order to develop environmentally friendly processes of PCB, advantages disadvantages existing PCB process are analyzed first. Aimed processes, physical is selected improved as solution recycling. process, a spray water superimposed on shredding smashing industrial dust irritant odor can be eliminated effectively. reduce noise impacts, equipments insulated within cabin mounted sound-absorbing materials it makes operators expose under 80 dB(A). end, environmental impacts assessed aspects resources consumption, wastewater, damages human health.
