A vibrating machines separates the cardboard and paper – different types of paper are sorted by hand and then baled. The remaining recyclables continue on another conveyor where steel cans are removed using magnets.

How do recycling companies separate materials?

Smaller items and containers fall straight through. Optical Sorters (Paper) – Pieces of paper go through two optical sorters to separate them into types and remove any containers that went over the disc screens. Cameras scan items as they pass by to identify newspaper, mixed paper or containers.

How are plastics separated for recycling?

Plastic. Optical sorters work like a giant eyeball by shining an infrared light on objects, that light bounces back sending a signal to the computer, which determines the type of plastic the object is made out of – when it finds what it’s looking for – it uses a puff of air to remove the material.

How do you separate papers for recycling?

The first step to recycle paper is to separate it by grade. It is then baled and shipped to a mill, where the paper is cleaned to remove ink, adhesives and non-paper products (like plastic windows in envelopes or staples). The resulting pulp is dried and rolled, then sent off to make new paper products.

How are metals separated in recycling Centres?

Basic metal sorting involves separating ferrous from non-ferrous metals. … When electric currents are induced across the remaining materials, metals are affected, and plastics are not. This is known as eddy current separation. Most materials recovery facilities now use this type of metal recycling equipment .

Why are plastics separated?

In fact, different plastic polymers have different characteristics and mixing them together would alter those characteristics. So, when recycling plastic, different polymers should be separated. This way, the outcome of each recycling process is a single type of plastic polymer, rather than a mixture of polymers.

What are the 5 steps of recycling?

In any recycling process, there are five key elements: Consumers, Haulers, Sorters, Reprocessors, and End Markets. That makes “recycling” somewhat complicated; but understanding it will make us better at recycling.

How are ferrous metals separated?

Ferrous metals are separated from the shredder residue by powerful magnets, while other materials are sorted out by hand or by jets of air.

Why is recycling metals cheaper than extracting them?

As recycling is easier than mining and uses less energy, it’s also cheaper. Lower metal prices lead to lower production costs and cheaper products for consumers.

Can food be recycled?

Food waste that cannot be avoided should be recycled where possible. To support successful food waste recycling, food waste must be separated from non-food waste items, such as disposable cutlery, as they may disrupt the recycling process.
