Paper recycling: the phases of paper recycling. What you get from recycled paper and all the useful information. How to explain paper recycling to children.

Who is on the hunt for oneresearch on paper recyclinglanded on the right web page. Here is some data on thepaper recycling in Italy and in Europe:

  • The production of paper, in Italy, sees 123 companies involved for 155 factories and 19,500 workers.
  • In Italy, paper production reaches over 8.8 tons per year with a turnover of 6.9 billion euros.
  • For the production of paper, both virgin raw materials and secondary raw materials are used, i.e. recycled paper.

The main user ofrecycled paper, in Europe it is Germany that spreads up to 35.2% of recycled paper. In Italy this percentage is around 10%.

What is obtained from recycled paper

From the card you can simply get more card. When the paper to be recycled is not of high quality, it ends up becoming paper or cardboard for packaging. Furthermore, cellulose fibers can be obtained from recycled paper to be used in green building.

The stages of the paper recycling process

The stages of paper recycling they are very complex. Just like I did for plastic recycling, I will try to explain this process by dividing it into different phases.

In prmis, the factories ofpaper recyclingthey mix the material to be recycled (used paper) with water and chemicals. The paper is shredded and heated so that it can be divided into cellulose fibers similar to the original virgin material.

The substance resulting from this first phase is called "cellulose pulp" or "Slurry". This compound is filtered through special selective sieves. Glue residues and plastic residues are removed. Plastic residues are widespread in cellulose pulp and derive fromlaminated paper.

The mixture will need to be treated to remove ink residue. The percentage of ink can represent up to 2% of the total weight of the recycled paper.

Once the ink has been removed, the paper can undergo a whitening process and then be transformed into new paper.

Paper recycling, advantages

Thepaper recyclingis convenient both from an economic point of view and from an environmental point of view. About 35% of the felled trees are destined for the extraction ofcellulosefor thepaper production.

Recycle a ton ofnewspapersaves us about a ton of wood!

Recycling a ton ofprint paper or copier paperinstead, we will save just over two tons of wood!

To produce virgin paper, the wood undergoes several treatments to extract the cellulose and separate it from other components of the plant cell wall. In particular, it is cumbersome to purify cellulose by eliminating lignin. This problem does not arise when using recycled cellulose pulp.

It has been estimated that if we were able to recycle half of the paper placed globally on the market, we would save the harvest of 20 million acres of forest.

20 million acres correspond to an area of ​​81,000 km².

Among othersadvantageseconomic and environmental, we remind you that with thepaper recyclingthe amount of energy and materials used in terms of electricity and water resources is drastically cut. Not only does it save raw materials (trees and cellulose), with therecyclingsome paperit saves energy and water.

Several calculations show that producing a ton of recycled paper (newsprint) saves about 4,000 kWh of electricity compared to the same amount produced from virgin material.

Producing paper from virgin raw materials would pollute the environment even more with direct contamination and harmful emissions. The US EPA Agency (United States Environmental Protection Agency)estimated that thepaper recyclingcuts water pollution by 35% and air pollution by 74%.

Children's paper recycling

Thepaper recycling, for children, it may be the right opportunity to learn notions ofplant biology, environmental education and home economics. The paper recyclingit can be easily introduced into any school curriculum and can also be explained at home.

For all the information on how to introduce paper recycling in a primary or secondary school, or simply to explain recycling to children, read the page: How to recycle paper at school.
