  1. 1. Recovery of Dialcohol Cellulose using Micro- and Ultrafiltration Processes

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Lina Näslund; Gabriella Petersson; [2023]
    Nyckelord :Membrane filtration; Ultrafiltration; Microfiltration; Dialcohol cellulose; DAC; Bioplastics; Chemical engineering; Process design; Technology and Engineering;

    Sammanfattning : The waste management and production of plastic play a concerning part in global warming and continues to have a negative effect on the environment. A promising strategy to address this challenge is to develop new sustainable materials, to replace current fossil-based plastics. LÄS MER

  3. 2. Fouling modelling in a UHT unit based on plant data.

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Thai Lam; [2023]
    Nyckelord :UHT; dairy; tubular heat exchanger; fouling development; fouling removal; food engineering; Technology and Engineering; Agriculture and Food Sciences;

    Sammanfattning : Heat treatment of dairy products is essential for food safety, one way to perform this is ultra-high temperature (UHT) processing. During the process, macronutrients and minerals form fouling deposits which impairs heat transfer. Eventually the fouling needs to be removed chemically by alkaline and acidic detergents. LÄS MER

  4. 3. Performance of a New Tetra Recart® Package Storing Oxygen Sensitive Food

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Thea Mathisson; Sofia Göransson; [2022]
    Nyckelord :Shelf Life; Ascorbic Acid; Vitamin C; Browning; Headspace; Tetra Recart®; Food Engineering; Agriculture and Food Sciences; Technology and Engineering;

    Sammanfattning : Tetra Recart® är ett innovativt, kartong-baserat förpackningsalternativ till konserverad mat. Tetra Pak® har sett en ökad efterfrågan på en mindre förpackningsvolym av Tetra Recart®, vilket har gjort att Tetra Recart® utvidgat förpackningsportfolion med en ny, mindre förpackning på 100 mL.

  5. 4. The impact of interface characteristics on the recyclability and repulpability of packaging material

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Ingrid Isacsson; [2022]
    Nyckelord :Tetra Pak ®; Recyclability; repulpability; packaging material; fiber-based barrier; chemical engineering; Technology and Engineering;

    Sammanfattning : The world is slowly moving towards a more environmentally friendly mindset and many companies, such as Tetra Pak® have followed this lead by producing more environmentally friendly products and developing better materials with less environmental impact. To accommodate these requirements, it is important that the package is recyclable. LÄS MER

  7. 5. The Investigation and Modeling of the interaction between Paperboard Clippings in a Pipe Flow

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Lea Christierson; [2021]
    Nyckelord :Fluid-structure interaction; paperboard material modeling; transient pipe flow; overset mesh; image analysis; Technology and Engineering;

    Sammanfattning : In the manufacturing process of Tetra Pak packages, holes are cut out of the paperboard for straws and caps. The left-over paperboard clippings, called confetti, need to be evacu- ated from the machine. However, this evacuation process has proven to cause problems due to jams arising as the confetti get stuck in joints and along the pipe walls. LÄS MER
