Subaru s EJ20G was a turbocharged 2.0 litre horizontally opposed or boxer four cylinder petrol engine. For Australia the EJ20G engine powered the GC/GM Impreza WRX from 1994 to 1996 key features of the EJ20G engine included its . Die cast aluminium block and cylinder head
Apr 23 2018 Circuit boards go to more complex areas to recover the gold and platinum. The type of recycling really depends on the type of material. Recycling especially when it comes to the recovery
Over recent times the value of gold has increased significantly making printed circuit board recycling even more viable than ever. If making money from items you would have just thrown away isn’t reason enough the Waste Electrical and Electronic Equipment WEEE Directive came into force in 2003.
Not all electronics contain gold. Central processing units CPUs pins and different kinds of circuit boards are all items that may contain gold with circuit boards being particularly desirable for this type of recycling.
