Aug 18 2008 Current recycling methods primarily recover only metals such as copper while non metal waste accounting for 70 per cent of the circuit boards go to landfills or incineration. Xu Zhenming and colleagues from Shanghai Jiao Tong University instead pulverised the non metal materials of PCBs mixing them with resin and polystyrene.
Further the technology behind the Integrated Circuit development continues to progress. Seemingly on a day to day basis. Thus IC chip technology rapidly becomes obsolete. This creates a vast market for recycle and reuse if
Yes waste circuit boards can be separated and recycled by burnning water washing or physical separation method. Remove precious metals from circuit boards with water type PCB recycling equipment The water type PCB recycling equipment adopts the wet gravity separation metal and nonmetal can be separated.
Printed circuit boards are currently coated with Br containing epoxy resins. With respect to recycling of the material removal of the halogen is important. Moreover it appears important to test whether recycling of the coating is feasible. The resin from circuit board reference material was extracted with extraction media containing supercritical carbon dioxide.
