What is Paper and Pulp Technology?

16 Jul,2019 | Blog

Although advancements in technology have reduced the use of paper in our society, paper is still a widely used product in our day-to-day lives. What are the steps for producing such a widely used material, though? The steps below will provide information on how to derive paper from raw materials by reactions with chemicals, heat, and electricity. Additionally, once the paper is manufactured, the product needs to be presentable and marketable for the end user.

Step by Step Procedure of Pulp and Paper Technology:

Preparing Raw Material:

Wood, in any form like a short log or long log or round or even chips, is received at the manufacturing unit. Depending on the shape and size, the logs are first de-barked by placing them in large tumblers and subjecting through a water wash. The debarked wood is then passed through a chipper to be cut into smaller sizes. Once that’s done, these smaller chips are sorted according to shapes and sizes and kept aside for further processing.

Fiber Separation:

This is the pulp-producing stage where the chips are placed in vessels and subjected to appropriate chemicals. After that, the chips are processed in steam at certain temperatures so that the fiber separates and dissolves to some extent. Once the cooked pulp is derived, they are sent to the chemical treatment chamber. Here they are cleaned, and water is extracted to prep it for the next step.


The pulp extracted contains lignin that imparts color pigments to the product. However, the paper needs to be white or light colored as required by many industries, or else the product is rejected. Therefore, the process of bleaching is essential. The pulp is lightened by passing through chlorination or oxidation. These can include chlorine dioxide, chlorine gas, hydrogen peroxide, sodium hypochlorite, etc. These chemicals destroy coloring impurities but keep the lignin and cellulosic unharmed, and can mitigate against the risk of product rejection.

Paper Processing:

The final step includes the bleached pulp is diluted with water to get a mixture having less than 1% of fiber. It is then cleaned with centrifugal force and then placed at the ‘wet end’ section of the papermaking machine. The mixture is then passed through the machine where it is processed, and white sheets of paper are derived as the end result.

The production process for pulp and paper can be complex, especially since the process is a favorable environment for bacteria and slime growth which can negatively affect the overall process. Please reach out to GO2 International to receive more information on how our chlorine dioxide can be effective for this production process.


Go2 is 21st-century chlorine dioxide technology.

Chlorine dioxide is a faster and more potent source of disinfectant capability without any worry of high Ph levels. This disinfectant is more soluble than others as it has a dissolving capacity 10 times faster than chlorine. Using chlorine dioxide is good for any sized company in need of slime control due to product efficacy at low ppm levels, low infrastructure needs and competitive product pricing. Please reach out with slime control needs and we will be happy to help.
