1. Anaerobic digestion in the kraft pulp and paper industry : Challenges and possibilities for implementation
Abstract : The pulp and paper industry is a large producer of wastewater and sludge, putting high pressure on waste treatment. In addition, more rigorous environmental legislation for pollution control and demands to increase the use of renewable energy have put further pressure on the pulp and paper industry’s waste treatment, where anaerobic digestion (AD) and the production of methane could pose a solution.

2. Decreased furnace wall corrosion in fluidised bed boilers - The influence of fuel lead content and sewage sludge additive
Abstract : Usage of used-wood fuel in the power industry has resulted in increased corrosion problems for metallic materials in the boilers, most probably due to relatively high amounts of chlorine, alkali metals and heavy metals present in the fuel.In this investigation, laboratory exposures were performed in order to study the influence of lead content in a wood-based fuel on the corrosion of selected materials.

3. Industrial applications and properties of oxalate-degrading enzymes
Abstract : Oxalate-degrading enzymes were investigated with focus on potential applications in the pulp and paper industry and in active packaging. Changes introduced to make the pulp and paper industry more environmentally friendly, such as recirculation of process-water streams and elementary chlorine free bleaching of pulp, have led to increasing problems with precipitation of calcium oxalate.

4. Nanoscaled Structures of Chlorate Producing Electrodes
Abstract : Sodium chlorate is mainly used for production of chlorine dioxide (a pulp bleaching agent). Sodium chlorate is produced by an electrochemical process where chloride ions (from sodium chloride dissolved in water) are oxidized to chlorine on the anodes and hydrogen is evolved on the cathodes.

5. Carbon materials: towards a circular economy through thermochemical recycling of mixed waste
Abstract : Carbon materials, such as paper, wood, plastic and textiles, play an important role in our everyday life, from clothes and packaging to infrastructure. However, the use of those materials follows a linear way. We take carbon resources, we make products, and we discharge them in a short amount of time, producing GHG emissions along its supply chain.
