  1. 1. Biogas production from a systems analytical perspective

    University dissertation from Environmental and Energy Systems Studies, Lund university

    Author : Maria Berglund; Lunds universitet.; Lund University.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiforskning; Energy research; indirect environmental impact; fuel-cycle emissions; environmental systems analysis; energy systems analysis; energy balance; digestate; Anaerobic digestion; biogas;

    Abstract : Anaerobic digestion and the production of biogas can provide an efficient means of meeting several objectives concerning energy, environmental and waste management policy. Interest in biogas is increasing, and new facilities are being built. READ MORE

  2. 2. Increase of Biogas Production at Wastewater Treatment Plants Addition of urban organic waste and pre-treatment of sludge

    University dissertation from Water and Environmental Engineering Department of Chemical Engineering Lund University P.O. Box 124 SE-221 00 Lund Sweden

    Author : Åsa Davidsson; Lunds universitet.; Lund University.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; kontroll av utsläpp; pollution control; Miljöteknik; Environmental technology; Miljöstudier; Environmental studies; biogas; anaerobic digestion; sludge; Wastewater; organic waste; methane;

    Abstract : Popular Abstract in Swedish Organiskt avfall utgör ett problem men är samtidigt en resurs med dess innehåll av näringsämnen och energi. Ett sätt att ta om hand organiskt avfall är att bryta ned det anaerobt genom s.k. rötning. READ MORE

  3. 3. Biogas production from lignocellulosic materials

    University dissertation from Water and Environmental Engineering Department of Chemical Engineering Lund University P.O. Box 124 SE-221 00 Lund Sweden

    Author : Li Sun; Sveriges lantbruksuniversitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Lignocellulosic materials such as agricultural plant residues are widely available in large amounts and can be used for production of biogas without the risk of competition for arable land. However, the intricate structure of lignocellulose, a major component of the plant cell wall, limits microbial degradation and consequently results in low degradation rate and low biogas yield.

  4. 4. Biogas production from thin stillage

    University dissertation from Water and Environmental Engineering Department of Chemical Engineering Lund University P.O. Box 124 SE-221 00 Lund Sweden

    Author : Jan Moestedt; Sveriges lantbruksuniversitet.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The biogas plant in Norrköping (Tekniska verken i Linköping AB, publ.), Sweden, operates with thin stillage, a residue from bio-ethanol fermentation, as the main feedstock. Thin stillage is energy-rich due to its high protein content, but due to its high nitrogen and sulphate content is a somewhat complicated feedstock. READ MORE

  5. 5. From waste problem to renewable energy resource exploring horse manure as feedstock for anaerobic digestion

    University dissertation from Gävle : Gävle University Press

    Author : Åsa Hadin; Högskolan i Gävle.; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; horse manure; environmental systems analysis; energy systems; renewable energy; environmental impact; anaerobic digestion; biogas; biofertilizer; systems perspective; bedding; incineration; composting; horse manure utilization;

    Abstract : A sustainable energy system requires, according to energy policies, reduced emissions of greenhouse gases, increased ratio of renewable sources of energy and more efficient use of energy. Horse manure could be regarded as waste, but also as a resource for renewable energy and plant nutrients. READ MORE
