With the availability of internet and increased environmental awareness, growing pressure for paper has slowly eased. However, global demands for pulp and paper continue to rise. This industry requires higher capital costs and consumes a great deal of natural resources. Under immense pressure, manufacturers contemplate on reducing costs and increasing production efficiencies, while trying to minimize impacts to the environment.

Oxygen and Carbon Dioxide can be utilized to accomplish these goals. They are essential to paper pulp manufacturing, such as:
  • Lignin stripping, bleaching, and ozone producing processes
  • Increase chemical recycling boiler or limekiln capability.
  • Oxygen plays a crucial role in Forestry’s waste water processing, especially in removing odor and initiating sludge activation process.
  • Carbon Dioxide is applied to PH water balance control in the paper-making industry. During the production of non-bleached paper, using CO2 is more economical and safer than sulfuric acid. Due to CO2’s high stability, it is much to easier control. In addition, in terms of recycled paper processing, CO2 can also replace sulfuric acid in the sanitization procedure with benefits of being equally economical, safe, and manageable.
  • Furthermore, during paper factories’ washing procedures, by adding CO2, can reduce PH concentration and boost chemical recycling thus leading to improvements in cost and re-use results.
