Recycling is a very important process for ours and next generations’ lives, because it gives a big chance to have a normal life in a natural (not too much destroyed) environment.

Recycling process

Recycling process transforms an exploited material (which very often is treated as a trash) to a new raw material which can be reused. Recycling helps to reduce the excessive production of raw materials, energy, and reduces air and water pollution.

There are many materials which can be recycled, such as: paper, metal, glass, plastics, etc.

OK then, but how to recycle plastics?

They are difficult materials to recycle, and sometimes the obtained product (the recycled raw material) is far from the original form.

The recycling process begins by sorting the wasted plastics by the type of the resin/polymer. Then they are segregated by the colour. After that, the prepared material is granulated and cleaned from the impurities, e.g. bottle labels. Next it is melted and extruded or injected in order to have a given shape, which then can be used by factories.

The presented process is only one, simple example of many other kinds of recycling processes. On its own, the recycling process can be very complicated, and this mostly depends on the material being recycled. Sometimes there can be more than one type of materials, like a products of sandwich technology (e.g. milk cartons).

Thanks to the recycling, we can take care of the natural environment more effectively and we don’t abuse the natural resources.
