1. 1. Bacteria - based self - healing mortar with bio - plastic healing agents : Comparative analysis on quantification and characterization of self-healing by various experimental techniques

   Master-uppsats, KTH/Betongbyggnad

   Författare :Rahul Roy; [2020]
   Nyckelord :Mortar; crack; autonomous healing; bacteria; bioplastic; lactic acid derivatives PLA ; alkanoate derivatives AKD ; internal crack geometry; quantification; characterization; statistical analysis; Bruk; sprickbildning; självläkning; bakteriebaserademedel; bioplast; mjölksyrederivat PLA ; alkanoatderivat AKD ; inre sprickbildning; kvantifiering; karakterisering; statistisk analys;

   Sammanfattning : Crack formation in concrete structures due to various load and non-load factors leading to degradation of service life is very common. Repair and maintenance operations are, therefore, necessary to prevent cracks propagating and reducing the service life of the structures. LÄS MER

3. 2. End-of-life scenarios for bioplastic food and drinking packages : a study of Swedish bioplastic waste disposal habitsand environmental impacts

   Kandidat-uppsats, SLU/Department of Molecular Sciences

   Författare :Tilda Hansson; [2018]
   Nyckelord :bioplastic; biodegradable plastic; compostable plastic; biobased plastic; PLA; Bio-PET; consumer;

   Sammanfattning : The aim of this study was to investigate real end-of-life scenarios for some of the most common bioplastics, such as PLA and Bio-PET, for food and drinking packages in Sweden and to evaluate some of the potential environmental consequences of these scenarios. Life Cycle Analysis often evaluate intended end-of-life scenarios for bio-plastic products, but this study used an explorative research method, gathering infor-mation of the conduction and habits of bioplastics to evaluate if these scenarios were the ones occurring.

4. 3. Production of bio-plastic materials from apple pomace : A new application for the waste material

   Uppsats för yrkesexamina på grundnivå, Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Författare :Jesper Gustafsson; Mikael Landberg; [2018]
   Nyckelord :Apple pomace; Orange pomace; Biodegradable; Plastics; Mechanical properties;

   Sammanfattning : Extensive quantities of apple pomace are generated annually but disposal of this waste is still much disputed. In EU alone, 500 000 tons are produced every year. Without further treatment, the acidic character of apples with their high sugar and low protein content makes the pomace unsuitable for landfilling and animal feedstock. LÄS MER

5. 4. About Solving and Dissolving : Investigating the design possibilities of bio plastic

   Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

   Författare :Tanja Marie Nitsche; [2018]
   Nyckelord :Biomorph; bio plastic; plant dye; surface design; sustainability; textile design; transparency;

   Sammanfattning : Translating the conceptual term of sustainability into materials and exploring bio plastics in order to generate visually and tacitly intriguing objects are the aims for this project. Other designers and previous projects in the field of textile design showed how the material works in a small scale. LÄS MER

7. 5. Bridging the circularity gap in the LDPE value chain: A Tetra Pak and PolyPlank case study in Sweden

   Master-uppsats, Lunds universitet/Internationella miljöinstitutet

   Författare :Margot Brahmi; [2018]
   Nyckelord :Plastic recycling; Circular economy; Material recovery; Low-Density Polyethylene; Polylaminated food and beverage packaging; Earth and Environmental Sciences;

   Sammanfattning : The consumption of single use and disposable packaging has led to significant amounts of waste. A large share of food and beverage packaging products are multi-layered aseptic cardboard packages laminated with aluminium and principally with the Low-Density Polyethylene (LDPE) plastic material.
