  1. 1. Prediction of Plastic Fragments in Recycled Paper Using Near-Infrared Spectroscopy

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

    Författare :Fidan Alieva; [2023]
    Nyckelord :Near-infrared spectroscopy; paper packaging; barrier materials; recycling; multivariate data analysis; Nära-infraröd spektroskopi; pappersförpackningar; barriärmaterial; återvinning; multivariat dataanalys;

    Sammanfattning : Sustainability has gained a lot of attention in the field of research. Researchers and consumers both prioritize sustainability and environmental issues over previously dominant materials, such as plastic. Packaging and disposable items that used to be made of plastic have largely been replaced with paper. LÄS MER

    Sammanfattning : This degree project at the Swedish University of Agricultural Sciences has been conducted in collaboration with IKEA of Sweden. The textile industry contributes to significant environmental challenges, including pollution and global water scarcity. LÄS MER

  4. 3. Quantitative and qualitative analysis of dyes in pulp from recycled textiles

    Master-uppsats, KTH/Fiber- och polymerteknologi

    Författare :Anna Bevin; [2023]
    Nyckelord :Textile fibers; Dyes; Kappa number; FTIR; UV-VIS; Textilfibrer; Färgämnen; Kappatal; FTIR; UV-VIS;

    Sammanfattning : To decrease the environmental footprint, the textile industry needs to become more circular. One company that is trying to close the textile lifecycle loop is the Swedish company Renewcell. In the Renewcell process, discarded clothes and other textile waste are turned into a dissolving pulp that can be used for production of new textiles. LÄS MER

    Sammanfattning : Byggbranschens utsläpp av växthusgaser utgör en stor andel av Sveriges totala utsläpp. För att minska de byggrelaterade utsläppen är det på många fronter som byggbranschen behöver förändras och effektiviseras. LÄS MER

  7. 5. End-of-life wind blade recycling through thermal process

    Master-uppsats, Uppsala universitet/Institutionen för materialvetenskap

    Författare :Kerstin Benz; [2023]
    Nyckelord :Wind Turbine Blades; Recycling; Glass Fiber Reinforced Plastic; Molten Salt Pyrolysis;

    Sammanfattning : Renewable energy production with wind turbines has been rising in the last 30 years and it is a crucial technology, which is necessary for the energy transition. As sustainable as the energy production of wind turbines is, the waste management of the blade material is not. Most of the blades end up on a landfill or get incinerated. LÄS MER
