Because it does not undergo a bleaching process, Suzano's Eucanatural pulp reduces the use of chemical inputs and offers a naturally brown appearance.
April 17, 2026 - Suzano announced the launch of its brown eucalyptus pulp known as Eucanatural to market. Eucanatural has been developed by Suzano's R&D team at the Aracruz Technology Center in Espírito Santo, Brazil, and currently being successfully produced on an industrial scale.
According to Suzano, this type of pulp is still not widely available globally and represents a high-performance alternative for the packaging, flexible paper, air filter, and various other applications, combining strength, lower environmental impact, and a characteristic natural appearance.
"Very few companies in the world produce brown pulp for the market," explained Lucas Ornelas Jacinto, senior researcher at Suzano. "At each stage of the process, we conducted the necessary tests and, after validating the potential, we launched the industrial campaign. Eucanatural stands out for its resistance and lower consumption of chemicals, since there is no bleaching stage."
The product idea emerged in 2020 and, between 2021 and 2022, underwent intense technical development work. During this period, Suzano's research team simulated all stages of the industrial process in the Technology Center's laboratory, evaluating physical and chemical properties and conducting pilot tests.
In 2023, the technology advanced to the first large-scale industrial campaign, with the production of thousands of tons and, recently, a campaign reinforced the effective entry of Eucanatural into the company's commercial portfolio.
Because it does not undergo a bleaching process, Eucanatural reduces the use of chemical inputs and offers a naturally brown appearance, ideal for packaging that aims to convey sustainability and authenticity. The product is suitable for packaging in general (cardboard boxes, shoe boxes, bags and other paper packaging applications that require robustness).
Ornelas pointed out that one of the segments that most absorbs brown pulp is that of flexible papers, such as wine labels, coffee bags, and air fryer papers.
"The market segment that buys the most brown pulp is that of flexible papers," Ornelas said. "The combination of technical performance and environmental attributes makes Eucanatural a strategic alternative in a world increasingly oriented towards renewable solutions. And at Suzano, we are committed to innovation, because that's where opportunities arise to improve the world and our own business."
Suzano is the largest hardwood pulp producer in the world, operating eight pulp mills in Brazil with a combined production capacity of 13.5 million tons per year of pulp. Based in Brazil, the company also produces paper and tissue.
