Wood is a natural product obtained from the trunks and main branches of the trees.
To obtain wood, these steps are followed:
• Felling or tree cutting.• Pruning or removing
branches that are not needed.
• Transport of logs to sawmills.
• Sawing of logs of wood into boards or planks.
• Wood drying.
• Paper is a thin material mainly used for writing upon, printing upon or for packaging. It is produced by pressing together moist fibers, typically celulose pulp derived from wood, rags or grasses, and drying them into flexible sheets.
