1. 16. 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.

   Nyckelord :Individual polybags; sustainability; circular economy; plastic; bioplastic; packaging; retail-industry; plastic recycling; waste management; China; Technology and Engineering; Earth and Environmental Sciences; Chemistry;

   Sammanfattning : This thesis provides an understanding and overview of the opportunities and challenges to enable a sustainable use of individual polybags used in the retail-industry. This was done by conducting a qualitative analysis including literature reviews, semi-structured interviews and e-mail correspondence. LÄS MER

4. 18. Applications of Solar Thermal Technology for Plastic Waste Management in Developing Communities

   Master-uppsats, KTH/Energiteknik

   Författare :Daniela Mewes; [2018]
   Nyckelord :;

   Sammanfattning : As the plastic industry continues to grow globally, with plastic materials contained in a vast quantity of consumer products, the management of the resultant waste has become one of the greatest challenges of our time. Greater than 8 million metric tons of plastics were estimated to enter the world’s oceans as of 2010, with an even larger amount remaining on land. LÄS MER

5. 19. A Finite Element Analysis of Crack Propagation in Interface of Aluminium Foil - LDPE Laminate During Fixed Arm Peel Test.

   Master-uppsats, Blekinge Tekniska Högskola/Institutionen för maskinteknik

   Författare :Pradeep Reddy Punnam; Chitendar Reddy Dundeti; [2017]
   Nyckelord :ABAQUS; Aluminium Foil; Cohesive Zone Modelling; Fracture Energy; Laminate; LDPE; Peel Test.;

   Sammanfattning : This thesis deals with numerical simulation of a peel test with an Aluminium foil and Low Density Poly-Ethylene (LDPE) laminate. This work investigates the effects of the substrate thickness and studies the influences of interfacial strength and fracture energy of the cohesive zone between the Aluminium and LDPE. LÄS MER

7. 20. Investigation of Polymer packaging films behavior subjected to tension and tearing
