1. Predicting Treatment Performance Using Ternary Plot : Macronutrients’ impact on biomass conversion efficiency
Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för geovetenskaperSammanfattning : Black soldier fly larvae (BSFL) waste treatment is becoming a more sought-after organic waste treatment since it produces larvae for animal feed as well as fertilizer, the need for prediction and optimization of treatment performance increases. This study aims to predict biomass conversion efficiency (BCE) for waste going into treatment, using only the nutritional data from other studies as it could give a good performance estimation while using available data.

2. Increase of biogas production by incorporating residual streams from agriculture
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : To expand the biogas production in Region Västra Götaland (RVG), residual streams from the agricultural sector can function as a large-scale supplier of biomass. The production of biogas decreases the dependence of fossil fuels and the digestate that is formed can also be returned to the agricultural sector, creating a closed loop. LÄS MER
3. The feasibility of using macroalgae from anaerobic digestion as fertilizer in Grenada : A literature study of the potential use of residue as fertilizer in Grenada, and a complementary laboratory study to evaluate the biogas potential
Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknikSammanfattning : Coastal areas in Grenada and the Caribbean are experiencing an abundance of stranded macroalgae. Climate change and eutrophication are probable causes of this inconvenience. This leads to logistic and economic dilemmas for the Caribbean societies. LÄS MER
4. Jämförelse av miljögiftshalter i fisk från Östersjön kontra västerhavet
Kandidat-uppsats, SLU/Department of Molecular SciencesSammanfattning : Syftet med denna uppsats är att kartlägga utbredningen av olika miljögifter i Östersjön och västerhavet med koppling till hur miljögifterna påverkar människors hälsa och vår miljö. Denna kandidatuppsats är en litteraturstudie där databaser tillgängliga vid Sveriges Lantbruksuniversitets bibliotek använts för att samla in information om ämnet. LÄS MER
5. Trophic transfer of per- and polyfluoroalkyl substances (PFASs) by glacial relicts in Lake Vättern, Sweden
Master-uppsats, Örebro universitet/Institutionen för naturvetenskap och teknikSammanfattning : The aim with the study was to assess if glacial relict amphipods constitute as vectors of transport of per- and polyfluoroalkyl substances (PFASs) in the Arctic char food web in Lake Vättern, Sweden. Sediment, surface water and biota samples were analysed for PFASs using ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS), and stable isotope analysis of δ 13C and δ15N was performed on sediments and biota samples.
