Lignocellulosic biomass can be utilized to produce ethanol, a promising alternative energy source produced through fermentation of sugars. However, in order to achieve high sugar and ethanol yields, the lignocellulosic material must be pretreated before the enzymatic hydrolysis and fermentation. Dilute acid pretreatment, using SO2, is one of the most promising methods of pretreatment for softwood
Expanding bio-energy can help to fight climate change and improve energy security. The bio-energy industry in the EU is booming. Much of this success is based on the supportive EU directives and strategies that are stimulating national policies and innovation processes. However, the bio-energy industry is being confronted with a number of interconnected challenges that threaten its reputation, leg

The lean stability limit of a prototype syngas burner is investigated. The burner is a three sector system, consisting of a separate igniter, stabilizer and Main burner. The ignition sector, Rich-Pilot-Lean (RPL), can be operated with both rich or lean equivalence values, and serves to ignite the Pilot sector which stabilizes the Main combustion sector. The RPL and Main sectors are fully premixed,
Bygg- och fastighetssektorn står för stora utsläpp av växthusgaser från byggnadsmaterial- och energianvändning. Byggbranschen står idag för ca en femtedel av Sveriges totala koldioxidutsläpp. Ett område med stor potential är byggnadsmaterial där IsoTimber är ett av företagen som driver utvecklingen framåt. IsoTimber är en relativt ny aktör inom byggsektorn som tillverkar prefabricerade väggar i trThe construction and real estate sector accounts for a large part of the emission of greenhouse gases from the usage of building material and energy. The construction industry today accounts for about one-fifth of Sweden’s total carbon dioxide emissions. One area with great potential is building materials where IsoTimber is one of the companies that drive the development forward. IsoTimber is a re
Green Hydrogen has been hailed as a game changer in climate actions, yet both global hydrogen markets and governance frameworks remain underdeveloped. The EU aims to pioneer a regulatory pathway, embedding hydrogen into its decarbonization governance framework. Centered on renewable hydrogen, the EU moves beyond “color-coding” technical classifications towards an emission-intensity-based legal def
The issue of the short microbiological shelf life of residues from the plant-based beverage industry creates a large food waste problem. Today, the oat beverage residue, in this study referred to as oat okara, is generally converted to energy or used as animal feed. High-pressure pasteurization (200 MPa, 400 MPa, and 600 MPa) was applied to oat okara to investigate the effect on shelf life and mic
Solid Waste Management RECOMMENDATIONS FOR KISUMU, KENYA Mistra Urban Futures Policy Brief 2019:1 Kisumu City generates approximately 400 tonnes of solid waste per day, 20%- 25% of which is collected to the open dump site. Of the total municipal solid waste that is collected, 65% is organic and another 27% is recyclable (County of Kisumu, 2015). The collection and handling of municipal solid waste

Online wall temperatures were measured with fiber-coupled phosphor thermometry in a full-scale gas turbine combustor. The combustor was operated with natural gas and up to 100 vol% hydrogen at engine-relevant conditions. Two phosphors were tested for this application, namely YAG:Dy and YAG:Tm;Li. Although YAG:Tm;Li seemed to be the most promising phosphor for this application, it turned out to be
A simplified description and a corresponding force field for polypeptides is introduced. Each amino acid residue is reduced to one interaction site, representing the backbone, and one or two side chain sites depending on its size and complexity. Site–site interactions are parameterized after a hydrophobicity criterium. The treatment of backbone sites is in addition designed to reproduce typical po
The entropy generation analysis of fully-developed turbulent heat transfer flow in inward helically corrugated tubes was numerically performed by using a Reynolds stress model. The simulations were conducted for a smooth tube and five cases of corrugated tubes with Reynolds number (Re) ranging from 10,020 to 40,060 at a constant wall temperature condition. The effects of corrugation pitch and heig
MAX IV is presently under construction at Lund, Sweden, and the first beam for the production of synchrotron radiation is expected to circulate in 2016. The whole set of 3 GeV ring beam pipes is coated with Ti-Zr-V Non Evaporable Getter (NEG) thin film in order to fulfil the average pressure requirement of 1×10-9 mbar, despite the compact magnet layout and the large aspect ratio of the vacuum cham
Popular Abstract in Swedish Hemoglobin, det protein som transporterar syre i blodet är förmodligen det mest välkända proteinet. Det är ett av många exempel på porfyrinproteiner, dvs. proteiner med en porfyrinring i det aktiva centrat. Porfyrinen kan binda en metalljon i mitten av ringen. När en järnjon är bunden kallas strukturen hem. Det är denna molekyl som finns i hemoglobin. I denna avhandling
The total of catalytic particles is often unavailable to participate in the electrochemical reactions in a PEFC, which limits the PEFC performance. The electrochemical surface area (ECSA) becomes an important metric to diagnose the catalyst layer's performance and evaluate the development of new electrode materials to achieve better overall efficiency. This work intends to analyze the effects of a
Popular Abstract in Swedish Avhandlingen är en studie av hur energianvändning och luftföroreningar i Polen, Estland, Lettland och Litauen har förändrats under övergången till marknadsekonomi efter 1989. Avhandlingen består av sex artiklar, vilka behandlar tre aspekter av dessa förändringar. I de tre första artiklarna analyseras energistrukturen i de baltiska länderna Artikel I) och Polen (ArtikelThis thesis is a study of how energy use and air pollution in Poland, Estonia, Latvia and Lithuania have been affected by the economic transition after 1989. It consists of six articles, which examine three different aspects of these changes. The first group of articles analyses the structure of energy use in the Baltic states (Article I) and Poland Articles II and III) at the outset of transitio
Wood charcoal is the main source of energy for cooking in urban Sub-Saharan Africa. It is widely known that charcoal production causes numerous environmental impacts, such as deforestation and environmental degradation. Interventions aimed at environmental improvements are common in Sub-Saharan Africa, however, there is limited focus on the trade-offs between the environmental and socio-economic i
Stigande energianvändning och global uppvärmning har lett till en ökad efterfrågan av förnyel-sebara energikällor. Ett alternativ är att utnyttja avloppsvatten för att producera biogas. Avlopps-vatten kan därav ses som en resurs snarare än avfall. I biogasproduktion används anaerob ned-brytning där mikroorganismer bryter ner organiskt material till metan. Primär rening är första steget inom avlopThe global heating has resulted in rising temperatures and more extreme weather conditions around the world. In combination with increasing energy demands, this has led to an increasing demand of renewable energy. One option is utilizing the wastewater to produce biogas. There-fore, wastewater can be seen as a resource rather than waste. Biogas production is based on anaerobic digestion where micr
