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

   University essay from Blekinge Tekniska Högskola/Institutionen för maskinteknik

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

   Abstract : 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. READ MORE

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

   University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

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

   Abstract : 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. READ MORE

4. 13. Degradation of Microplastic Residuals in Water by Visible Light Photocatalysis

   University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

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

   Abstract : 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.

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

   University essay from Lunds universitet/Internationella miljöinstitutet

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

   Abstract : 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.
