A lot of time, energy and money are also saved in this process. So, paper recycling should be carried out more often.

During recycling of paper, paper is broken down into

Cellulose
-
Plastic
-
Screens

All of the above
The process of waste paper recycling involves mixing of used paper with water and chemicals to break it down. It is then chopped and heated, which breaks it down further into strands of cellulose, a type of organic plant material; this resulting mixture is called as pulp or slurry. It is strained through screens, which remove any glue or plastic that may still be in the mixture then cleaned, de-inked, bleached, and mixed with water. Then it can be made into new recycled paper or other products.

Paper is made from the cellulose fibres which are obtained from the wood of the trees. The cellulose fibres are converted to pulp. This pulp is treated with various chemicals and then dried to form the sheets of paper. There are substances like lignin in the wood of trees which results in the paper to become yellow and brittle over some time. So, the yield from the trees for paper production is about 95%.
