Material recovery and separation from leftover printed circuit boards


The Waste Electrical and Electronic Equipment (WEEE) Directive (European Commission, 2003) mandates that member states do more than just dump waste electrical and electronic equipment in landfills; instead, they must repurpose, recycle, and recover it. According to Williams (2005), WEEE is made up of a broad range of devices, such as control instruments, TVs, computers, mobile phones, electrical tools, and medical equipment. The WEEE Directive mandates the ecologically sustainable processing of printed circuit boards as part of this waste management strategy. Printed circuit boards are found in many electrical appliances, including computers and TVs, as well as other appliances like washing machines, which are increasingly adopting printed circuit boards for functions like pre-programming and timers. Printed circuit boards provide unique recycling challenges due to their diverse composition of metals, glass fiber, and organic materials. According to Goosey and Kellner (2002), just 15% of the 50,000 tons of discarded printed circuit boards generated in the UK in 2002 were recycled. According to Fisk et al. (2003), waste printed circuit boards are currently either sent to landfills, where hazardous compounds may seep into the water supply, or burned, which may result in the formation of toxic brominated compounds from the brominated flame retardants contained in the circuit boards. read more

It’s dragged a pal’s small horse trailer around a few occasions (4500-ish lbs with 1 horse in it, most likely 500 or slightly more on the tongue). Pulled nice, although a WD system would have been good. Compared to the same trailer behind an F-150, however, the Jeep is like pulling it round with a tractor. It drives properly, however the trailer seems important, quite than seeming like it’s simply following you around. read more
