1. 11. Experimental Testing and MaterialModeling of Anisotropy in InjectionMoulded Polymer Materials

   Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Författare :Sharlin Shahid; Widaad Gukhool; [2020]
   Nyckelord :Anisotropy; Barlat2004; DIC; Hill48; Polyethylene; Tensile test;

   Sammanfattning : Experimental characterization of the mechanical properties in a thin injection moulded Low-Density Polyethylene (LDPE) plate is per- formed in this work. Anisotropy in LDPE at different material orientations is measured from the Digital Image Correlation (DIC) observation of the specimens during uniaxial tensile test. LÄS MER

3. 12. Development of a Nakajima test and its potential variants setup on thin flexible LDPE film and Aluminum foil

   Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Författare :mohamed shahen; [2019]
   Nyckelord :Nakajima test; DIC Digital image correlation; Abaqus; Ductile damage; Thin packaging laminates;

   Sammanfattning : The thesis aimed to identify fracture strain for multiaxial loading for laminate material of Al and LDPE that is mostly used in the food packing technology specially in liquid packaging industry. These materials are thin and flexible which make it difficult to handle and test it. LÄS MER

4. 13. Utvärdering av karboniserad LDPE som egenskapsförbättrande tillsats i nya LDPE-filmer

   Uppsats för yrkesexamina på grundnivå, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

   Författare :Engin Cömert; [2018]
   Nyckelord :karbonisering; återvinning; miljö; LDPE;

   Sammanfattning : Tidigare forskning har visat att med hjälp av en speciell mikrovågsugn så kan man omvandla lågdensitetspolyeten (LDPE) till kemikalier med högre värde [1]. Ett försök på att omvandla plastavfall (LDPE) till en produkt med högre värde kommer att göras i detta projekt. LÄS MER

5. 14. Saving the world - One truck at a time : A case study at Volvo Trucks on reducing the packaging waste through circular economy

   Master-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Författare :Amanda Orrefalk; Charlotta Nedström; [2018]
   Nyckelord :Circular economy; Reversible logistics; Sustainable packaging; Waste management; Cirkulär ekonomi; Reversibel logistik; Hållbara förpackningar; Avfallshantering;

   Sammanfattning : The production and consumption of today generates huge amounts of waste, and due to the increasing living standards the amount will continue to increase. The waste leads to large environmental impacts due to pollution and emissions of greenhouse gases, as well as the depletion of raw materials. LÄS MER

7. 15. Degradation of Microplastic Residuals in Water by Visible Light Photocatalysis

   Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

   Författare :Tajkia Syeed Tofa; [2018]
   Nyckelord :Microplastics; Low density Polyethylene LDPE ; Heterogeneous photocatalytic degradation; Zinc oxide nanorods; Visible light.;

   Sammanfattning : Microplastic (MP) pollution has recently been recognized as a threat to the biosphere including humans due to its widespread distribution, persistent nature and infinitesimal size. This study focused on the solid phase degradation of microplastic residues (particularly low density polyethylene, LDPE) in water through heterogeneous photocatalysis process by designed photocatalysts of zinc oxide nanorods (ZnO NRs) and platinum nanoparticles deposited on zincoxide nanorods (Pt NPs-ZnO NRs) under visible light irradiation.
