  1. 1. Individual-tree-selection in uneven-sized Norway spruce stands in southern Sweden : Developments of tools for simulation and optimization

    Författare :Nils Fagerberg; Johan Bergh; Peter Lohmander; Stergios Adamopoulos; Hubert Hasenauer; Linnéuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; continuous cover forestry; selective cutting; Picea abies; uneven-aged; single-tree-selection; growth model; knot size model; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : Individual-tree-selection (ITS) is a continuous cover forestry method that aims to utilize the uneven-sized stand structure through optimized individual tree selections. ITS is an interesting management alternative to rotation forestry in terms of production of multiple benefits and forest owner profitability. LÄS MER

  3. 2. Towards low-emitting and sustainable particle and fibreboards : Formaldehyde emission test methods and adhesives from biorefinery lignins

    Författare :Venla Hemmilä; Stergios Adamopoulos; Luísa Maria Hora Carvalho; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Wood board industry; chamber methods; dynamic microchamber DMC ; bio-based adhesives; lignosulfonates; supercritical water hydrolyzed lignin; crosslinkers; fibreboards; particleboards; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : High volumes, fast production speed, and low material costs have been historically the driving factors of the particle- and fibreboard industries. However, in recent years the fossil-fuel dependency and health issues of the formaldehyde-containing adhesives used in the production have gained attention from both legislators and consumers.

  4. 3. Acid-catalyzed Liquefaction of Industrial Side-streams for Producing Wood Adhesives and Particleboard

    Författare :Wen Jiang; Stergios Adamopoulos; Sheikh Ali Ahmed; Sergej Medved; Carsten Mai; Johannes Konnerth; Linnéuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Bark; Catalysts; Industrial side-streams; Liquefaction; Oat husks; Optimization; Particleboards; Polyurethane; Polyhydric alcohols; Wood adhesives; Wood sawdust; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : Big quantities of residues and side-streams are generated annually from forest-based and agricultural industries all around the world and present a relatively unexplored renewable resource. Due to the absence of a regularly updated and systematic database of supply, industrial residues and side-streams usually end up in landfill disposal, are used for energy generation, or remain at the production sites.

  5. 4. Birch Stem and Wood Traits in Genetic and Silviculture Trials in Southern Sweden

    Författare :Grace Jones; Stergios Adamopoulos; Mateusz Liziniewicz; Mikael Andersson; Sheikh Ali Ahmed; Erkki Verkasalo; Linnéuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; acoustic velocity; Betula spp.; dynamic MOE; genetic parameters; grain angle; hardwood; Itrax densitometry; mixed forests; non-destructive testing; stem form; akustisk velocitet; Betula spp.; blandskog; densitometri; genetiska parametrar; icke destruktiva metoder; Itrax; lövträ; skogsodling; stamkvalitet; vedsegenskaper; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : Swedish tree species of birch (silver: Betula pendula and downy: B. pubescens) are often neglected during forest management activities, resulting in low value logs. This thesis investigated birch stem characteristics and wood properties important for solid wood products, in genetics and management trials in southern Sweden. LÄS MER

  7. 5. Agro-industry feedstock and side stream materials for wood panel manufacturing

    Författare :Nicolas Neitzel; Stergios Adamopoulos; Reza Hosseinpourpia; Thomas Walter; Heiko Thömen; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : Wood-based panels are indispensable in many areas, such as the construction industry and furniture production. The intensified demand for renewable materials, rising wood prices and increasing protection zones of forest areas make the wood panel industry consider alternative raw materials. LÄS MER
