Although after recycling they must test the boards as the recycling process might damage certain parts of the board. In addition because of the excessive use of this type of circuit board in the electronic manufacturing industries recycling printed circuit boards reduces solid waste landfill and land pollution.
The high technical recyclability of platinum group metals means that over 95 recovery can be achieved once pgm containing scrap reaches a state of the art refining facility. Technical challenges exist but the main barriers to recycling pgms lie in ensuring the collection of scrap and in the capacity and technical capabilities of recycling chains around the world.
