For the Pulp and Paper Industry

Merichem® offers cost effective, quality soda makeup chemicals, helping paper mills further their sustainability initiatives through our extensive capabilities and unmatched expertise.

Quality Matters in Paper Manufacturing

Because quality cannot be compromised, Merichem® continually adheres to the highest standards. We analyze chemical composition on deliveries. We conduct tank quality checks monthly. With our own lab and chemists, we test spent caustic and sodium hydrosulfide products regularly to ensure we meet your standards. Our pulp processing chemical products include:

What are Makeup Chemicals in Papermaking?

Caustic Soda in the Kraft process or Sodium Hydroxide in soda pulping are used to break the lignin bonds of wood being processed into pulp for papermaking. Using recycled chemicals as makeup from other sources (spent caustics) aids in the reduction of the environmental impact of chemical pulping.

Promoting Sustainability

In addition to offering significant cost advantages, the use of spent caustic products helps promote recycling and environmental sustainability in other industries. To underscore our commitment to these initiatives, we adhere to the standards set forth in the American Chemistry Council’s Responsible Care® program and the American Fuel & Petrochemical Manufacturers (AFPM), and have implemented the RideTight® Fluid-Sealing Management program on our rail cars to help mitigate the risk of odors.

Water Conservation

By supplying recycled spent caustic products, Merichem® helps pulp and paper companies reduce their fresh water usage.
