The first stage is to run the products through the Querstromzerspaner - it's called "the QZ" for short, because the German for "chain mill" is too much of a mouthful for SWEEEP operatives.This behemoth of a machine works like a hurricane to spin everything together and smash it apart. It creates an enclosed tornado in which metals and aluminium cut softer materials such as plastics so no other cutting tools are required.This is a very efficient way of breaking down the WEEE because it requires minimum pre-dismantling, has low operating costs and ensures the highest quality output materials.The effect is to disassemble everything to its constituent parts: metals, plastics, rubber and batteries.Next, these materials are sorted using magnets - anything that contains iron is filtered out automatically - and then by hand. Desirable material and hazardous elements are picked out by hand to be recycled appropriately.
