A brief summary of the parer making process:
1. Trees are cut down. made into logs and debarked
2. The logs are chipped and put into large reactors where the chips are cooked for hours with a chemical that breaks down the lignins which hold the wood fibers together. The chemicals can be sulfides or caustics.
3. The resulting pulp of cellulose fibers is cleaned, mixed with fillers (clay) and other chemicals and spread onto a moving belt which extracts the water.
4. The pulp fibers become tangled and make a thin belt of paper which is pressed and polished (calendered) into its final surface form and stored on rolls.
Steps not covered in this description include:
- recovery of wood chemicals
- recycling of the cooking chemicals
- energy efficiency
- use of post consumer recycled paper
- pollution control
- waste reduction
- environmental issues

Why is paper necessary?
Strictly speaking, it isn't. But many people think it's a great idea. Recycling paper means that less trees gets felled to make paper, and less paper has to go to landfills. Making paper out of paper also use up less energy than making paper from trees, so society save some there too.
How are paper plates made?
Paper plates are made of paper. Paper used in making paper plates is made of mainly wood material.
Why do we recycle paper?
We recycle paper to save trees, reduce waste in landfills, and conserve energy and resources used in making new paper.
What are the environmental problems with paper making?
There are many environmental problems that are related with paper making. This entails cutting down trees which will affect rainfall in a significant manner.

What type of wood is paper made out of?
Paper is typically made from wood pulp, which can come from various types of trees such as softwood (e.g. pine, spruce) or hardwood (e.g. oak, birch). Different trees yield different quality of paper based on their fiber length and composition.
Is pine wood good for making paper?
No, pine wood is not commonly used for making paper as it contains high levels of resin and lignin, which can affect the quality of the paper. Softwood trees like pine are typically used for making products like lumber, not for paper production. Hardwood trees like birch and oak are more commonly used for making paper due to their fiber content.
When was paper making discovered?
Paper wasn't originally made from trees so if your wanting to know the trees answer I haven't a clue but the other style as I know it was around the early Egyption period.
