1. Produktion av polyhydroxialkanoater (PHA) med Bacillus megaterium
Kandidat-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : Plastproduktionen och användningen av plast ökar varje år i hela världen och detta är ett av världens största problem. Plaster är ett svårnedbrytbart ämne och processen kan ta hundratals år. Detta leder i sin tur till att plastackumuleringen orsakar skadlig påverkan på klimat, miljö och människor. LÄS MER
2. Dispersed bio-based binders as drop-in solution for non-woven industry
Master-uppsats, KTH/Fiber- och polymerteknologiSammanfattning : Sammanfattning på svenska: Målet med projektet var att utveckla ett system av disperserade bindemedel för non-wovenindustrin som inte förutsätter omfattande förändringar i befintliga processer. Bindemedlet ska vara biobaserat, bionedbrytbart och endast bestå av byggstenar som är matkontaktsgodkända av FDA och BFR. LÄS MER
3. Engineering Rhodosporidium toruloides for the production of polyhydroxybutyrate
Master-uppsats, Lunds universitet/Teknisk mikrobiologiSammanfattning : The increased use of plastics has become an environmental problem where plastics, due to the slow degradation, accumulate in the oceans and landfills. Although plastics are a very cheap and useful material with desirable properties and a wide variety of applications, they are primarily made from petroleum-based resources which are non-renewable and of fossil origin.

4. Analysing and concluding the cost/performance matrix for biopolymer blends with different renewable contents
Master-uppsats, Lunds universitet/Centrum för analys och syntesSammanfattning : Due to increasing awareness and consumer demands it has become important for companies to develop an economical and environmentally sustainable alternative to traditional petroleum-based plastics. The transition from fossil material to bio based is important for the future of people and planet, still, how the transformation should be implemented is yet unknown. LÄS MER
5. Development of Kraft Lignin and Coating Technique to Prepare Coated Urea Fertilisers with Increased Nutrient Use Efficiency
Master-uppsats, KTH/Skolan för kemivetenskap (CHE)Sammanfattning : Coating urea to prepare controlled release N-fertilizer has been considered as an effective way to increase its nutrient use efficiency, thus reduce its waste and the consequent harmful environmental impacts. Inorganic sulphur and synthetic polymers have been used in the industry as coating materials together with utilization of various types of expensive coating equipment which commonly requires also complicated technical setup and controls.
