Recycling centers use a variety of methods to separate paper, plastic, and metals from the truckloads of material brought in by city recycling pickups. These methods include:
Manual sorting: Workers on a conveyor belt manually sort the materials into different bins.
Magnetic separation: Magnets are used to separate ferrous metals, such as iron and steel, from the other materials.
Eddy current separation: Eddy currents are used to separate non-ferrous metals, such as aluminum and copper, from the other materials.
Air classification: A stream of air is used to separate lighter materials, such as paper, from heavier materials, such as plastic and metal.
Optical sorting: Optical sensors are used to identify and sort different types of materials, such as paper, plastic, and metal.
These methods are often used in combination to achieve the highest possible recycling rates.
