1. Sustainable food packaging based on polyhydroxyalkanoate
Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomiSammanfattning : 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. LÄS MER
2. Wastewater Characterisation for Design and Modelling of Primary Settlers at Municipal Wastewater Treatment Plants
Master-uppsats, Lunds universitet/Industriell elektroteknik och automationSammanfattning : The primary settling tank (PST) is often one of the first treatment steps at a wastewater treatment plant (WWTP) and is the first process in the plant to remove significant amounts of suspended solids. Its role in wastewater treatment however, has oftentimes been neglected and little effort has been made to optimize and model the process. LÄS MER
3. Geobacillus 7349 – A new potential biosurfactant producing microorganism
Master-uppsats, Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)Sammanfattning : The main aim of this master project is to find out whether strain Geobacillus 7349 can produce biosurfactant during their growth by extraction and characterization of the product. The other goal is to optimize the cultivation condition of the strain. LÄS MER
4. Chemical modification of starch in order to get thermoplastic properties
Kandidat-uppsats, KTH/MaterialvetenskapSammanfattning : There are numerous advantages of replacing traditional non-biodegradable synthetic plastics with bio-based plastics. Starch is globally available, cheap, renewable, and biodegradable. However, starch has a poor product performance and is relatively difficult to process, as conventional melt processing techniques cannot be used. LÄS MER
5. The effect of fiber structure on chemical modification of cellulosic fibers
Kandidat-uppsats, KTH/KemiteknikSammanfattning : För att skapa ett hållbart samhälle måste material av fossilt ursprung ersättas med förnyelsebara och miljövänliga alternativ. Ett sådant alternativ är cellulosa från vedfibrer, som har stor potential att kunna ersätta många fossila material i framtiden. LÄS MER
