1. 1. Sustainable food packaging based on polyhydroxyalkanoate

   University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Author : Safana Al-Ashor; [2024]
   Keywords : Biopolymers; Sustainable food packaging; Circular economy; Biobased and biodegradable materials; Food packaging; Processing technologies; Food quality; Shelf-life;

   Abstract : The Norwegian Food Research Institute (Nofima) and the University of Borås worked together to develop this project. The commonly used packaging materials pose a serious threat to the environment, as they are produced from nonrenewable crude oil and cannot decompose naturally. READ MORE

3. 2. Formulation development, rheological characterization, and cosmetic evaluation of gel-creams

   University essay from Lunds universitet/Livsmedelsteknik och nutrition (master)

   Author : Carl Pontén; [2024]
   Keywords : Rheology; Texture analysis; Viscometry; Semisolids; Design of Experiments; Critical Process Parameters; Critical Quality Atttibutes; Pharmaceutical Technology; Technology and Engineering;

   Abstract : Oil in water (o/w) emulsions are thermodynamically unstable systems composed of small oil droplets dispersed in a continuous aqueous phase. This means that given enough time, the two phases will separate. Pharmaceutical emulsions are used as a method of administering the Active Pharmaceutical Ingredient (API) for topical applications.

4. 3. Thermal Conversion of Cellulose-Lignin Precursors into Carbon Fibres

   University essay from Uppsala universitet/Nanoteknologi och funktionella material

   Author : Sofia Westberg; [2023]
   Keywords : Carbon fiber; lignin; cellulose; continuous conversion;

   Abstract : Carbon fibres are used in many applications thanks to their exceptional tensile properties in relation to their relatively low weight. These thin strands of at least 90% carbon are mixed with a matrix such as epoxy to form composites used for cars, wind turbines, prosthetics, and many other things. READ MORE

5. 4. Modelling the chemical recycling of plastic waste via pyrolysis and analysing integration with existing refinery infrastructure

   University essay from Lunds universitet/Kemiteknik (CI)

   Author : Simon Dahl; [2023]
   Keywords : Pyrolysis; Recycling; Integration; Modelling; Simulation; Techno-economic; Plastic; Chemical engineering; Technology and Engineering;

   Abstract : Current plastic management is unsustainable as large amounts of plastic end up landfilled or in the ocean, necessitating an expansion of waste management infrastructure. Pyrolysis is a viable chemical recycling option, and in this report a pyrolysis model is constructed in Aspen Plus. READ MORE

6. 5. Screening pyrolysis bio-oil as binder for carbon anode in aluminium production

   University essay from KTH/Fiber- och polymerteknologi

   Author : Yazhe Wang; [2023]
   Keywords : Biomass; Bio-oil; Bio-pitch; Carbon Anode; Aluminum production; Biomassa; Bioolja; Biobeck; Kolanod; Aluminium Produktion;

   Abstract : Den högkvalitativa stenkolstjäran, som används som anodbindemedel inom aluminiumindustrin, innebär utmaningar när det gäller att möta kraven på kolanod. Dess produktion är beroende av ohållbara fossila bränslen, vilket bidrar till ökade koldioxidutsläpp. READ MORE
