In the Western societies, accustomed to high consumption and a "use and dispose" lifestyle, the amount of solid waste generated has become a serious problem.

Among all the waste that we generate, plastic has acquired a special role: it is in most sectors and in a large number of products: water and beverage bottles, detergent cans, parts of household appliances and automobiles, furniture, elements of decoration, pipes, plastics for agriculture, trays, and more.

In 2010 alone, the amount of plastic waste produced in Europe exceeded 24 million tons, and today it is impacting our ecosystem. 

So far, the best method that has been practiced by manufacturing industries is plastic recycling which is believed to be the most effective way of limiting the introduction of new materials into our already polluted environment. 

To achieve this, there are 2 main methods for recycling into new products, which are mechanical recycling and chemical recycling. The mechanical method involves the following; washing and cleaning, classification, crushing or shredding, washing, pelleting, extrusion, injection, blow molding, and compression. 

But a very important phase in the mechanical recycling process is the plastic shredding and that will be our focus in this article.

Plastic shredding.

This is a basic process within the chain of mechanical plastic recycling. The plastic shredding process is achieved using the plastic shredding machinery. This machine is designed to efficiently cut and crush the plastic materials thus reducing them to smaller and even sizes.

What is the purpose of shredding the plastic?

Plastic is a material that has great properties, but when it comes to recycling it stands out one above the other: it has a lot of volume and little density, that is, it takes up a lot and weighs little.

The shredding process provides us with a homogeneous material, the same size and a very similar shape, regardless of the shape and size they originally have.

You can deposit plastic bottles, chairs, boxes, which will result in small materials that are easy to transport and store.

How does a plastic shredding machinery work?

Basically it is made up of a more or less large inlet, which allows access to the plastic parts and which is prepared to avoid, as far as possible, projecting parts to the outside.

A rotor incorporates several blades that, thanks to the power and speed of rotation, cut and crush the plastic parts.

Then, it passes through a sieve or through a grid that only allows passage to pieces of a desired size. Finally, it goes through a tape to a warehouse where the product is stored.

There are many types of crushers, with different sizes, powers and speeds. Choosing between one and the other will depend on the type of material that we are going to want to crush.

 

And what is done with the plastic shredding?

Once we have all the pieces of plastic separated according to material and clean, we proceed to recycling them by manufacturing new products.

The most common ways of working are:

Extrusion

Injection

Molding

Compression
