If you consider the range of all types of electronics the number of different items is staggering as is the variation. From a simple mouse to a telephone exchange - all need to end up somewhere and preferably not a landfill.
An electronics recycler is essentially a massive sorting operation. Batteries go with other batteries sorted by type. Metals with other metals again sorted by type. Eventually we reduce everything down to it's component parts which are then shipped to one of our audited downstream vendors for further processing.
The R2 and RIOS standards which we adhere to are extremely exacting and we are regularly audited for compliance. This means we have to account for everything that comes in and everything that goes out all the way to final disposition. Nothing goes to the landfill.
