Introduction.Kraft black liquor is a side-stream produced during the kraft pulping process containing lignin, hemicelluloses and cooking chemicals. The stream is usually evaporated and burned in the recovery boiler to recover the cooking chemicals and generate energy. The mill is, however, often/sometimes limited by recovery boiler capacity, and removing some of the lignin from kraft black liquor
Introduction. Electrodialytic processes have become relevant technology in promoting sustainability within the food industry. Bipolar membrane electrodialysis (EDBM) offers an efficient and eco-friendly alternative for skim milk (SM) acidification, eliminating the need for added acids that affect milk properties and mineral composition [1-2]. In this study, the fouling behavior of bipolar membrane
Introduction. Cellfion is a company developing PFAS-free membranes based on chemically functionalized nanocellulose. The membranes are highly tuneable and exhibit favourable properties such as high selectivity, low resistance and low swelling. Cellfion’s membranes have shown potential for use in different applications such as electrodialysis, fuel cells, electrolyzers, humidification syste
Fermentation intensification is crucial for the economic viability of biobased chemical production through fermentative routes, including a shift from batch/fed-batch to continuous fermentations to enhance volumetric productivity. This is especially relevant for the Acetone Butanol Ethanol (ABE) fermentation due to low productivities and concentrations caused by product toxicity. However, transiti
Recycling industrial wastewater is a significant challenge due to its complexity. However, achieving the global sustainable development goal 6—clean water and sanitation—requires suitable treatment technologies to upgrade and recycle water, thereby reducing drinking water consumption and water stress. This presentation focuses on two challenging wastewater streams:carwash and oily wastewater, demo
IntroductionThe pulp and paper industry is one of the most significant industrial sectors globally. Current pulp mills primarily focus on producing pulp fibers and electricity. By transforming traditional pulp mills into lignocellulosic biorefineries, they can become a cornerstone of a future circular bioeconomy. To achieve this, pulp mills must close their process loops and, in addition to fiber
IntroductionGlobal water scarcity necessitates innovative approaches to water treatment. Membrane technology has emerged as a key solution, demonstrating its effectiveness across a range of applications, from seawater desalination using reverse osmosis to wastewater treatment with membrane bioreactors. This presentation will introduce three novel water treatment concepts based on membrane technolo
Although Russian President Vladimir Putin is the only person who can end the war in Ukraine almost immediately, peace on the “Western Front” that he himself created is not necessarily just his free choice. The question is whether Putin and his circle of power can still afford a ceasefire with a neighboring country that they have plundered and destroyed – and to what extent. The answer is not only
Monuments to Joseph Stalin and Felix Dzerzhinsky are constantly increasing in contemporary Russia. However, new monuments to Lenin are no longer being built. From the perspective of today’s strongmen, Stalin and Dzerzhinsky represent strength, war victory and domestic “iron order”. Lenin, on the other hand, is seen as a political adventurer and destabilizer. As a man who, according to Vladimir Put
December 20th is marked in the Russian calendar as a day dedicated to the workers of the "security organs". However, these are not just any "organs" that have security in their job description. In this case, the term “security organs” emphasises exclusively the importance of foundation of political police in the emerging Soviet Russia.On December 20, 1917, the Russian Communist Party established i
Putin kan välja att avsluta kriget i Ukraina – frågan är om han har råd med det. Fred är farligt, i alla fall om man är president i Ryssland. Och respekten för den som tappar makten försvinner snabbt. Att eskalera spänningar är därför en ren självbevarelsedrift. Ukraina är en huvudvärk för Putin, men den är inte hans värsta, skriver historikern Tomas Sniegon vid Lunds universitet.
BackgroundDespite the central role of forensic medical examinations in child physical abuse cases, evidence on how their findings impact prosecution is scarce.ObjectiveWe studied the association between the dependent variable, filing of formal charges, and independent variables related to the child, suspect, and case characteristics, the acts of violence, and forensic findings, such as cutaneous l
Lars Marcus’s book Städernas stenar (The stones of cities) presentsbasic concepts and the latest directions in the space syntax researcharea. Marcus’s presentation is based on the necessity of understandingthat urban planning as an area of knowledge is comprised of the materialreality of both the city and the “lived city”, human beings, and their useof the city as a tool, of being comprehended as
To address the absence of the comprehensive analysis of energy-water-carbon emissions nexus between large-scale economies and different industries and the inability to predict policy impacts across industrial hierarchies, this study develops a novel framework integrating environmentally-extended multi-regional input-output analysis with structural decomposition analysis and policy-driven scenario
Permafrost degradation and desertification have been identified as two major land surface processes occurring on the Qinghai‒Xizang Plateau. However, the effect of desertification on permafrost degradation remains poorly understood. In this study, land surface process simulations are used to demonstrate that climate change, characterised by increased warming‒wetting trends alongside reduced contin
China's rapid growth in electricity demand intensifies the twin challenges of water conservation and carbon reduction in a system where production and consumption are spatially mismatched. We develop a novel evaluation framework to quantify how electricity generation and interprovincial transmission redistribute “virtual” water and carbon. The method integrates national water/carbon footprints by
This article explores the theoretical origins of modern Russian anti-and decolonial discourse. It has been demonstrated that the roots of Soviet anti-colonial policy are to be found in discussions about the interpretation of the right of nations to self-determination that began among the left at the end of the 19th century. The Leninist interpretation of this concept determined the Bolshevik polic
Electrospun nanofiber membranes (ENMs) with unique porous 3D network structure exhibit properties such as high porosity and surface area, fine-tuned surface functionality and uniform pore sizes. This makes them candidates for water/wastewater applications with excellent flow. This study focuses on the fabrication of polymeric and composite ENMs from polyacrylonitrile (PAN) and nanoclay (NC) and th
