Material is only unloaded in the areas set aside for this purpose. During the unloading of material, it is visually inspected by an operator of the organisation to verify that no unauthorised material is unloaded. If during the unloading process it is seen that unauthorised material is being unloaded, two procedures are followed:
The supplier is instructed to pick it up and take it away.  If the supplier refuses to take it back, the material is photographed and filed with the supplier’s documentation. This material is separated from the material to be sorted and deducted from the initial weight, as long as it is not hazardous and is not included in the unacceptable or ineligible materials.
Unloading can be manual or, if they come by lorry, by unloading the lorry.
