The EU supply stability of primary source pgms is uncertain given the market dominance by a small number of non EU countries the ongoing political economic and social factors in these regions and the EU’s reliance on imports. Between 2017–2019 recycling only provided 25– 33 of the global demand for palladium platinum and rhodium.
Waste management does not merely reduce waste from the environment but also eliminates the impact of harmful greenhouse gases like methane carbon monoxide and carbon dioxide. This decreases the reliance on landfills for waste deposit that adversely affects the environment. Energy Conservation Recycling is a big part of waste management.

The process for recovery of copper and precious metals from printed circuit board edge trim is similar to that from waste printed circuit boards. In general the edge trim is 0 10 20 30 40 50 60 urry de m
Collection Waste WEEE is collected from designated WEEE drop off points and taken away for processing. Sorting Hand sorting takes place to extract materials such as batteries and copper for quality control purposes before materials are shredded to reduce their size to approximately 100mm. This prepares material for the secondary process and ensures equipment with
Jan 14 2020 Electronic waste or e waste refers to any discarded products with a battery or plug.The biggest e waste categories are small and large appliances and heating/cooling equipment.

Metal Recycling Preparation. With scrap metal the general rule is a product needs to be at least 50 percent metal. Even if that metal is surrounded by other materials like plastic it’s worth recycling if it’s made mostly out of metal. If you have products with only a small amount of metal but it’s easy to remove separate the metal.
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.
