6. Concentration of Proteins and Decrease of Salt Content in a Hydrolyzed Fermentation Broth Using Membrane Filtration
Master-uppsats, Lunds universitet/Kemiteknik (CI)Sammanfattning : Membrane filtration was used to concentrate proteins and decrease the salt concentration in a hydrolyzed fermentation broth. The broth was a by-product from the bacterial production and extraction of polyhydroxyalkanoates (PHA), that can be used to produce biobased plastics. LÄS MER
7. Slamhantering från reningsverk : Ett utmanande problem
Kandidat-uppsats, Linnéuniversitetet/Sjöfartshögskolan (SJÖ)Sammanfattning : Vid vattenrening produceras slam som restprodukt. Slam innehåller en stor mängd ämnen, såsom metaller, medicinrester och olika näringsämnen. I Sverige produceras flera hundra tusen ton årligen. Innehållet måste hanteras, men hur görs det idag och hur kommer det att hanteras i framtiden. LÄS MER
8. Production of natural pigments from A. platensis grown on wastewater from local treatment facility.
Master-uppsats, Lunds universitet/Teknisk mikrobiologi; Lunds universitet/BioteknikSammanfattning : Although microalgae have been considered for the biological treatment of wastewater since the 1950’s, their potential to efficiently remove pollutants from various streams remains largely untapped and is yet to be utilized at large scale. The production of algal biomass and extraction of high-value compounds has, however, become increasingly popular with large scale farms and biorefineries around the world producing many promising alternatives to petroleum-based products and processes.

9. Optimization of alloys recovery in steel scrap sorting : Technological, economic and environmental considerations for a better chromium, nickel and molybdenum recovery in steel scrap
Master-uppsats, KTH/MaterialvetenskapSammanfattning : Today’s steelmaking industry is highly dependent on steel scrap supply. In order to reduce the greenhouse gas emissions (GHGs) deriving from the steel industry, it is of utmost importance to ensure that high percentages of steel scrap are recycled, reducing the reliance on the traditional ore-based steelmaking, which is significantly more environmentally impactful.

10. Quality of Spent Mushroom Compost Amended with Organic Material- Effect on Nutrient Content and Plant Growth
Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)Sammanfattning : Peat, as a non-renewable growing media, poses environmental concerns due to extraction and decomposition processes, leading to increased greenhouse gas emissions. Alternatives growing media with potential to replace or reduce the use of peat are of great need. LÄS MER
