   Abstract : This thesis explores the integration of hydrogen and battery energy storage systems as a means to enhance the management of wind and solar power in the pursuit of a greener grid. The objective of the study is to identify the potential benefits and challenges associated with hybrid energy storage systems (HESS) and their role in renewable energy integration. READ MORE

4. 8. Mapping and analysing the current waste paper recycling system in Europe for a new fiber-based packaging material

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

   Author : Hande Seker Cakal; [2023]
   Keywords : Separate waste collection; material recovery; material recycling; extended producer responsibility; fiber-based cushioning packaging; Separat avfallsinsamling; materialåtervinning; utökat producentansvar; fiberbaserad dämpningsförpackning;

   Abstract : Fiber-based packaging has emerged as an alternative to plastic packaging, driven by concerns regarding environmental impact and excessive usage of plastic. In response to market trends favouring circular packaging solutions, Stora Enso is preparing to introduce Papira, an innovative fiber-based cushioning packaging material, in Europe. READ MORE

5. 9. 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)

   Author : Anna Wagne; [2023]
   Keywords : Lignin; extraction; hydrophobicity; chemical engineering; Technology and Engineering;

   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

6. 10. Scalable Nonparametric L1 Density Estimation via Sparse Subtree Partitioning

   University essay from Uppsala universitet/Statistik, AI och data science

   Author : Axel Sandstedt; [2023]
   Keywords : density estimation; scalable density estimation; nonparametric density estimation; scalable nonparametric density estimation; L1; L_1; anomaly detection; regression analysis;

   Abstract : We consider the construction of multivariate histogram estimators for any density f seeking to minimize its L1 distance to the true underlying density using arbitrarily large sample sizes. Theory for such estimators exist and the early stages of distributed implementations are available. READ MORE
