Paper is one of the most common products you can find anywhere globally. It can be accessed almost anywhere as it is sold in most parts of the world. Considering it comes from trees, which are semi-perishable products, its availability has been attributed to people’s assumptions that trees are infinite. Due to the recent emergence of global warming, and trees playing a major role in inhibiting this effect, cutting down trees has been looked down upon recently. Innovative and more conservative methods of working in this industry are now required.

What happens in the Pulp and Paper Industry?
The pulp and paper industry consists of factories that utilize wood as raw material to produce paper, pulp, paperboard, and other cellulose-based products.
The paper and pulp industries are one of the largest industries in the world due to their complex nature involving different types of mills, processes, and products. The process hugely determines the quality of effluents produced. Therefore, the complexity of the industry means that the requirements for effluent and water treatment vary significantly at different points of the manufacturing process.
Environmental legislation and enforcement also play a significant role in determining the processes used.
Due to the vast amounts of resources in terms of water and wood needed every year, the wastewater and solid wastes are also significant in size and require treatment. An environmentally-friendly way is necessary to treat these wastes as most wastewater is usually let back into the natural water system.
Some of the main processes done when making paper include:
- Pulping procedure performed to separate and clean the fibers
- Pulping is followed by refining procedure
- Dilution process to create a thin fiber mixture
- Pressurization to increase the material density
- Drying to remove the thickness of materials
- Completion procedure to provide an appropriate surface for usage
The various types of paper and paperboard products made include:
Linerboard and Corrugating Medium
Liner Boards are made of Kraft pulp, famous for its high strength. Corrugated boards are 3-ply cardboards made of two paperboard facers to each side of a fluted core to increase strength and stiffness while maintaining low weight and cost.
Fine and Specialty Papers
The products include business/writing and technical paper with properties that include surfaces suitable for writing or printing and dimensional stability. Wrapping paper and Kraft paper sacks that are natural or have been bleached are used in paper packaging despite the stiff competition from plastics.
Some familiar products like foodstuffs are packaged by bleached paperboard like the milk carton.
These are various lightweight papers ranging from napkins, toilet tissue, wrapping, toweling, and book tissue, with properties that include absorbency, bulkiness, and strength.
These are commodity products with regulated properties like printability, low cost, and more, all necessary to enhance readability.
The onset of the computer brought about the reduced need for storing information using files made from paper but stored electronically. However, the expected impact of computer information storage systems has not been as significant.
