  1. 1. SAWING STRATEGIES FOR TROPICAL HARDWOOD SPECIES : Simulation studies based on industrial conditions of Mozambique

    Författare :Pedro Ah Shenga; Dick Sandberg; Olof Broman; Mats Nylinder; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sawing strategies; tropical hardwood species; simulation; volume yield; log grading; umbila; jambirre; Träteknik; Wood Science and Engineering;

    Sammanfattning : The harvesting of Mozambique tropical hardwood species is considerable higher than the natural regrowth in the forest and the stock is decreasing drastically. Therefore, it is important to improve the material recovery when the wood is refined (i.e., in sawing and further refinement to products such as joineries, furniture etc. LÄS MER

  3. 2. Potentials and wood fuel quality of logging residues from indigenous and planted forests in Mozambique

    Författare :Rosta Mate; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Search for complementary and alternative renewable energy sources is imperative to meet the current growing demand for wood fuel and for diversification of electricity supply sources in Mozambique. Logging residues from timber harvesting operations and whole tree biomass from short rotation coppice (SRC) are available options. LÄS MER

  4. 3. Biomass and stem volume estimates for valuable timber species in Mozambique

    Författare :Rosta Mate; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Accurate aboveground biomass and stem volume estimates are crucial for the management of Mozambique's forests. This study focused on the development of aboveground biomass and stem volume equations for the three most valuable commercial timber species in Mozambique, Afzelia quanzensis Welm. (Chanfuta), Milletia stuhlmannii Taub. LÄS MER

  5. 4. Mild Wet Torrefaction and Characterization of Woody Biomass from Mozambique for Thermal Applications

    Författare :Carlos Alberto Cuvilas; Weihong Weihong Yang; Tobias Richards; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; Wet torrefaction; Fast Pyrolysis; kinetics; Catalyst;

    Sammanfattning : Mozambique has vast forestry resources and also considerable biomass waste material such as bagasse, rice husks, sawdust, coconut husks and shells, cashew nut shell and lump charcoal waste. The potential of the total residues from the agricultural sector and the forest industry is estimated to be approximately 13 PJ. LÄS MER
