Green Low-Carbon Transition and Chemical Localization: Insights from LATAM PAPER 2026 on Process Evolution and Technological Frontiers in Global Large-Scale Pulp Mills

1. Frontier Technology Insights: Process Solutions for High Energy Consumption and Stock Preparation System Contaminants

At this year’s LATAM PAPER Core Technology Forum, global pulp and paper equipment and process giants delivered a very clear technological signal: under conditions of raw material and supply chain volatility, the core of future process evolution lies in “extreme control of energy consumption per ton of pulp” and “efficient fiber quality management.”

• System Energy Saving and Decarbonized Pulping:
Valmet and Andritz respectively presented their latest digital and green low-carbon pulping optimization solutions. The core logic of both focuses on maximizing process heat recovery and reducing pumping electricity consumption through integrated restructuring of stock preparation and pulp handling systems.

•  Fiber Modification and Strength Optimization:
In the mid-to-late stage of pulping process bottlenecks, industry expert Bellmer Cellwood provided an in-depth analysis of how, through refined mechanical and chemical modification methods—without increasing chemical additive intensity—it is possible to enhance the fiber network structure and achieve cost reduction and efficiency improvement.

•  Flow System Disturbance Control:
Large pulp mills are widely facing pain points caused by chemical interference in stock preparation systems. Pulp and paper industry giant CMPC detailed the technical bottlenecks in high-speed machine operation, such as sheet breaks and shutdowns caused by deposition of stickies. Meanwhile, Kadant Lamort shared its latest technological breakthroughs in efficient screening in the stock preparation stage, targeting the interception of trace contaminants and stickies.

These technological evolutions centered on efficiency, energy saving, and integrated chemical processes are becoming the core focus of the global pulp and paper industry.

2. Supply Chain Restructuring: Technical Discussion on On-Site Hydrogen Peroxide (H₂O₂) Integrated Solutions for Pulp Mills

With the continuous expansion of commodity pulp capacity in Latin America, large pulp mills have raised higher technical requirements for the stable supply and overall cost of the key bleaching chemical—high-purity hydrogen peroxide (H₂O₂).

During technical and business exchanges at the conference, there is a clear emerging demand trend for “localized and integrated self-supply chemical models.”

In discussions with representatives of global specialty chemicals and pulp bleaching chemical giant Nouryon, both parties conducted in-depth technical exchanges on “on-site hydrogen peroxide plant solutions for pulp mills”, and mutually introduced their respective process coverage and professional service scope. At the same time, several global market leaders in commodity short-fiber pulp and forest products—including Suzano, UPM, and Bracell—also showed strong interest in this integrated and localized chemical supply model.

Traditional bulk hydrogen peroxide relies on long-distance road or maritime transportation, which not only leads to high logistics carbon footprint due to ineffective water content during transport, but also presents risks of degradation during long-distance shipping, as well as significant safety and supply chain volatility risks.

By constructing high-purity hydrogen peroxide plants inside or near large pulp mills, and directly connecting upstream chemical production with downstream pulp bleaching processes via pipelines, this has become a consensus solution for global million-ton pulp mills to optimize cost per ton of pulp and achieve absolute supply chain security.

3. Process Innovation: Empowering Large Pulp Mills with Fully Acidic Anthraquinone Technology

As an original technology supplier and EPC contractor with independent intellectual property rights, Kdison possesses mature processes and extensive international delivery experience in “fully acidic anthraquinone hydrogen peroxide (H₂O₂) production technology.”

Our successful delivery and stable operation experience in large cross-border pulp mill projects such as the RAPP project in Indonesia and the PRI project demonstrate the technical feasibility of constructing highly automated, high-standard chemical plants inside or adjacent to large pulp and paper mills, fully compliant with international best practices.

This technology adopts a fully acidic process design, which significantly increases single-train capacity (e.g., meeting ultra-high capacity requirements exceeding 200 tons per line), while substantially reducing overall energy consumption and catalyst usage.

This not only helps pulp mills completely eliminate safety risks and logistics costs associated with long-distance transportation of bulk chemicals, but also enables significant optimization of total bleaching cost per ton of pulp, supporting customers in achieving stringent emission reduction targets.

In the future, targeting the practical technical pain points of large pulp mills in Latin America, Kdison will continue to rely on technology as its foundation, and work hand in hand with partners to jointly promote the low-carbon transformation of the global pulp, paper, and chemical industries.
