  • Safarian, Sahar; Unnthorsson, Runar (MDPI AG, 2018-06-07)
    This paper describes the development of a model to comprehensively assess the sustainability impacts of producing lignocellulosic bioethanol from various types of municipal organic wastes (MOWs) in Iceland: paper and paperboard, timber and wood and ...
  • Safarian, Sahar; Unnthorsson, Runar; Richter, Christiaan (American Society of Mechanical Engineers, 2020-01-21)
    Wood and paper residues are usually processed as wastes, but they can also be used to produce electrical and thermal energy through processes of thermochemical conversion of gasification. This study proposes a new steady state simulation model for down ...
  • Safarian, Sahar; Unnthorsson, Runar; Richter, Christiaan (Elsevier BV, 2019-05-13)
    Currently around 10% of all energy generated worldwide comes from biomass. Most of this 10% is biofuel energy from the fermentation of corn and sugarcane. Fermentation of corn competes with the global food supply, and fermentation of sugarcane drives ...
  • Fu, Weiqi; Guðmundsson, Steinn; Wichuk, Kristine; Palsson, Sirus; Pálsson, Bernhard Ö; Salehi-Ashtiani, Kourosh; Brynjolfsson, Sigurdur (Elsevier BV, 2019-03)
    To convert waste CO2 from flue gases of power plants into value-added products, bio-mitigation technologies show promise. In this study, we cultivated a fast-growing species of green microalgae, Chlorella vulgaris, in different sizes of photobioreactors ...
