  1. 1. Timber as a forest-risk commodity: embodied socio-ecological impacts in the Brazilian supply chain

    Författare :Caroline Sartorato Silva Franca; Chalmers tekniska högskola; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Environmentally-extended input-output model; Land use; Supply chain traceability; Forest frontiers; Sustainable Forest Management SFM ; Forest degradation; Illegal logging;

    Sammanfattning : The continued loss and degradation of forest resources is one of the largest sustainability challenges of our time. The past decades rise in global demand for agricultural and forest commodities have created unparalleled pressure on the natural resources, leading to forest destruction and associated loss in carbon stocks, invaluable biodiversity, ecosystems services, livelihoods.

  3. 2. Ash Products for Nutrient Recycling in Forestry : Leaching and Drying Characteristics

    Författare :Peter Mellbo; Tommy Claesson; Sirkku Sarenbo; Hans Samuelsson; Högskolan i Kalmar; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Ash products; Wood ash; Leaching; Drying; Nutrient; ; Sustainable forestry; Forestry; Skogsskötsel; Miljövetenskap; Environmental Science;

    Sammanfattning : As the demand for carbon dioxide neutral energy sources increases, forestry becomes more intensive. Entire trees are removed from the felling sites threatening the nutrient balance of the forest soils. LÄS MER

  4. 3. Shape stability of laminated veneer products

    Författare :Lars Blomqvist; Dick Sandberg; Jimmy Johansson; Magdalena Sterley; Linnéuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; adhesive; beech; birch; bending; laminated veneer products; moulding; shape stability; spring-back; twist; veneer; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : This thesis is about the shape stability of laminated veneer products.Laminated veneer products consist of veneers bonded together with adhesive into a predetermined shape. Such products are used in several contexts but especially in furniture manufacture. LÄS MER

  5. 4. Carbon Balance Implications of Forest Biomass Production Potential

    Författare :Bishnu Chandra Poudel; Inga Carlman; Johan Bergh; Thomas Lundmark; Roger Sathre; Mittuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; forest management; silviculture; clear-cut forestry; continuous-cover forestry; substitution; total carbon; climate benefit; climate change; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : Forests in boreal and temperate forest-ecosystems have importance for carbonbalance since they sequester large amount of atmospheric carbon by uptake ofcarbon-dioxide during photosynthesis, and transfer and store carbon in the forestecosystem. Forest material can be used for bio-fuel purposes and substitute fossilfuels, and supply wood products, which can replace carbon-and-energy-intensivematerials. LÄS MER

  7. 5. Bioenergy from Swedish forests : A Study of extraction methods, quality and effects for forest owners

    Författare :Daniel Nilsson; Johan Bergh; Peter Lerman; Gudmund Vollbrecht; Nasko Terziew; Linnéuniversitetet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; logging residues; forest fuels; moisture content; needles; nutrients; moisture content measurements; Norway spruce; dry-stacking; fresh-stacking; Forestry and Wood Technology; Skog och träteknik;

    Sammanfattning : The forest constitutes a very important element of renewable natural resources and makes a significant contribution to the Swedish bioeconomy. Biofuels are Sweden’s largest source of energy; of all the energy we use, 32% comes from biofuels, and of this approximately 85% comes from the forest and the forestry sector. LÄS MER
