Your challenges

Water management in the pulp and paper industry is at a pivotal moment, where sustainability meets operational excellence. By addressing current challenges and embracing new opportunities mills can ensure a resilient and sustainable future.

High levels of water and energy consumption

Pulp and paper production is resource-intensive and growing freshwater scarcity and limited permits are putting added pressure on mills. Reducing water intake through reuse and optimizing energy-use across treatment are now essential for improving efficiency, cutting costs, and meeting sustainability targets.

Ensure environmental compliance without compromising on performance

Stricter environmental regulations are pushing mills to reduce emissions, effluent loads, and overall ecological impact. The challenge lies in meeting these compliance standards without sacrificing operational efficiency, production capacity or product quality, which demands innovative, high-performance treatment solutions.

Reusing and recovering water and materials

Freshwater scarcity and increasingly limited permits for its use are driving mills to reduce water consumption through reuse. Maximizing water reuse and recovering by-products such as fibers and biogas are key to improving sustainability and cost-efficiency.

Inefficient water and wastewater management

As production speeds increase and product quality requirements become more stringent, the demand for high-quality process water is greater than ever. Many facilities also struggle with outdated or undersized treatment systems that are unable to meet modern operational and quality demands.

How does NSI handle your needs?

We’re here to help you navigate the evolving water challenges in the pulp and paper industry. Every mill is unique, facing specific operational demands, environmental requirements, and efficiency goals. That’s why our innovative, mill-wide approach is tailored to address your mills individual needs, unlocking new levels of performance, sustainability, and cost-effectiveness.

We offer an innovative approach to:

  • Reduce water consumption and energy costs with efficient integrated solutions.
  • Recycling water across the mill by closing water loops and reuse effluent while maintaining quality.
  • Recover valuable resources like energy and fibers to cut waste and unlock added value
  • Remove treatment bottlenecks by upgrading systems to handle load variations and boost reliability.
  • Meet regulatory compliance and optimize mill-wide performance performance with future-proof treatment strategies that reduce risks and ensure long-term profitability
