  2. 1. Performance of on-site systems and a green wall for greywater treatment

    Author : Mashreki Sami; Annelie Hedström; Elisabeth Kvarnström; Inga Herrmann; Sahar Dalameh; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VA-teknik; Urban Water Engineering;

    Abstract : Greywater contains inorganic and organic substances, nutrients, pathogens, micropollutants and microplastics. Source-separated greywater using decentralized systems can potentially provide energy-efficient and low-maintenance treatment. READ MORE

  4. 2. Mechanical behaviour of hardwoods : effects from cellular and cell wall structures

    Author : Ingela Bjurhager; Lars Berglund; Ingo Burgert; Magnus Wålinder; KTH; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Wood fibre and forest products; Träfiber- och virkeslära;

    Abstract : Syftet med den här avhandlingen var att undersöka mekaniska egenskaper hos olika arter av lövträd, och koppla egenskaperna till cell- och cellväggsstrukturen i materialet. Arterna som omfattades av undersökningen var Europeisk asp (Populus tremula), hybridasp (Populus tremula x Populus tremuloides) och ek (Quercus robur). READ MORE

  5. 3. Fracture behaviour of Green Wood (Pinus Sylvestris L.) : a composite materials approach

    Author : Fredrik Thuvander; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Polymera konstruktionsmaterial; Polymeric Composite Materials;

    Abstract : The fracture behaviour of green wood has been investigated using a composite materials approach. Through fracture experiments on miniature specimens, it was found that drying of wood leads to damage not only on the macro-level but also at the scale of the cell wall. READ MORE

  6. 4. Lytic polysaccharide monooxygenases for green production of cellulose nanomaterials

    Author : Salla Koskela; Qi Zhou; Markus Linder; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cellulose; enzyme; CNC; CNF; LPMO; nanocellulose; wood; Biotechnology; Bioteknologi;

    Abstract : Cellulose is the main structural polymer in wood, and its potential in the form of nanomaterial building blocks, nanocelluloses, has now been recognized. Nanocelluloses, including cellulose nanofibers (CNFs) and cellulose nanocrystals (CNCs), have become increasingly important in development of modern sustainable materials. READ MORE

  7. 5. Bioplastics from Biomass - Acetylation of Xylans with Green Chemistry

    Author : Agnes Stépán; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : There is social, environmental and increasing economic pressure on the industrial sector to substitute non-renewable resources with renewable ones as the increasing World population is exponentially depleting the fossil fuel supplies of the Earth. Each year about 260 million tons of plastics are produced from crude oil and most of it ends up as waste. READ MORE
