1. Modeling PFAS Transport in Groundwater - Exploring current approaches and evaluating parameter importance
University essay from Lunds universitet/Väg- och vattenbyggnad (CI); Lunds universitet/Teknisk geologiAbstract : PFAS contamination in drinking water is a current problem, and new regulations for drinking water limits were recently implemented in each member country of the EU in January this year. Understanding the spread of PFAS in groundwater is therefore important to prevent it from reaching drinking water sources. READ MORE

2. Investigation of Milled Wood Lignin Extraction Using Enzymatic Hydrolysis for Application in Hydrophobic Barriers in the Food Packaging Industry
University essay from Lunds universitet/Kemiteknik (CI)Abstract : The objective of this report is twofold: to optimise the extraction method of lignin from spruce altering a few process parameters and to investigate the use of lignin as a hydrophobic barrier in food applications. The process used was STEX (steam explosion) pretreatment followed by enzymatic hydrolysis and MWL (milled wood lignin) extraction using a mixture of dioxane-water. READ MORE

3. Post-Wildfire Debris Flows: Mapping and Analysis of Risk Factors in Western North America
University essay from Uppsala universitet/Institutionen för geovetenskaperAbstract : Climate change is leading to in an increase in frequency and severity of wildfires, which in turn can result in the formation of runoff-initiated post-wildfire debris flows. This type of debris flows is, like most debris flows, triggered by heavy precipitation events. READ MORE

4. Fiber based biocomposite material with water and grease barrier properties
University essay from KTH/Fiber- och polymerteknologiAbstract : Syftet med denna studie var att utveckla en biokomposit med både fett-och vattenbarriär. Material med dessa egenskaper innehåller idag ofta PFAS-molekyler (per- och polyfluorerade alkylsubstanser). Det är av stor betydelse att byta ut dessa mot ett biobaserat alternativ då de är giftiga och ackumuleras i naturen. READ MORE

5. Development of waterborne and mild curing DWRs, formulated with fully bio-based substances
University essay from KTH/Fiber- och polymerteknologiAbstract : ”Durable water repellents (DWR) är textilimpregneringar som bidrar med vattenavvisande egenskaper som håller länge på funktionella tyg. Tyvärr är dessa hydrofobiska ytbehandlingar vanligtvis en källa till skadliga och persistenta kemikalier och de även är producerade från fossilbaserade resurser. READ MORE
