Expertise in Pulp and paper

Environmental requirements from customers, authorities, and society are growing to address today's sustainability challenges related to climate and resources. In the packaging industry, companies are expected to understand the environmental impact and carbon footprint of their packaging and activel…

If we could replace as little as 10% of all plastic used around the world with fibres from forestry and agriculture, this would be equivalent to at least 25 million tonnes a year.

Stock preparation is a crucial factor in paper production. Our expertise in stock preparation is based on extensive research with low-concentration grinding, screening, fractionation with both sieves and hydrocyclones and measurement techniques for fiber properties. We can develop new concepts, opt…

Fibre-based products are becoming more formable and the development of these materials and production processes are advancing. When it comes to replacing plastics in packaging, formed paper or moulded fibre packaging products are becoming one of the most attractive renewable alternatives.

Good water management allows papermakers to mitigate the negative impacts of contaminant accumulation in process water streams. This can result in an improvement of product quality and process stability along with reduced costs, energy consumption, and water consumption.

RISE has a team of experts working with different processes for separation of lignin from various kraft and soda liquors. The focus of the work is on optimisation of the processes and process parameters for different liquors, but also to modify the properties of the lignin products in order to suit…

Numerical simulation - such as Finite Element Methods (FEM) - as a tool is useful to understand and predict material, product, and process performance.

Are you looking for energy efficient pulp production or improved bulk in your board grade? RISE could be your helping hand.

Studying wood can provide insights that are crucial to answering several important questions in the pulp and paper industry, one of which is whether it is possible to introduce new wood species into production while maintaining the desired properties of the resulting pulp.

Optimising and analysing processes and products in the pulp and paper industry is crucial for optimising production, improving quality and reducing environmental impact. Careful analysis can identify inefficiencies, optimise raw material use and ensure that end products meet the required specificat…

Everyone benefits from even production and less waste. However, some connections between variations in the process and undesirable properties in the product could be difficult to find with everyday working methods. RISE performs complementary measurements and analysis of the process and the product…

The analysis of cellulose in pulp mills is crucial for efficient operations and high-quality pulp production. One of the most important factors is the raw material – the wood.

Paper and paper-based packaging are produced from renewable raw material which can be recycled and reused. Over 50 percent of the paper and packaging produced in Europe use recycled fibre as raw material and the rate will most likely increase in the future. RISE offer our expertise to improve and d…

A Kraft pulp mill has many different process streams and it is important to keep track of the energy and mass balances in order to optimize the process and troubleshoot operational problems. RISE has available models for this that can be used in various investigations and to simulate how new proces…

White liquor is used in the Kraft cooking process to liberate the fibers in the wood. A vital step in the white liquor preparation is causticization, where green liquor is converted to white liquor, which requires good quality lime. The lime is produced in the lime cycle, which is sensitive to diff…

Formation of various precipitates that disturbs the process are common in the pulp and paper industry and can result in large losses of production. RISE has a unique competence and experimental equipment for investigating causes and solutions to these problems, where two examples are scaling in bla…
