  1. 1. Energy analysis for sustainable mega-cities

    Författare :Aumnad Phdungsilp; Björn Palm; Ivo Martinac; Charles Heaps; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Asian mega-cities; energy demand; metabolism of cities; energy modeling; sustainable energy; energy planning; multi-criteria decision-making; Mechanical energy engineering; Mekanisk energiteknik;

    Sammanfattning : ABSTRACT Cities throughout Asia have experienced unprecedented economic development over the past decades. In many cases this has contributed to their rapid and uncontrolled growth, which has resulted in a multiplicity of problems, including rapid population increase, enhanced environmental pollution, collapsing traffic systems, dysfunctional waste management, and rapid increases in the consumption of energy, water and other resources.

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

    Författare :Åsa Hadin; Ola Norrman Eriksson; Karl Hillman; Nils Ryrholm; Jaana Sorvari; Högskolan i Gävle; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; AGRICULTURAL SCIENCES; LANTBRUKSVETENSKAPER; TEKNIK OCH TEKNOLOGIER; LANTBRUKSVETENSKAPER; ENGINEERING AND TECHNOLOGY; AGRICULTURAL SCIENCES; horse manure; environmental systems analysis; energy systems; renewable energy; environmental impact; anaerobic digestion; biogas; biofertilizer; systems perspective; bedding; incineration; composting; horse manure utilization;

    Sammanfattning : 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. LÄS MER

  3. 3. Efficiency Improvements in Waste-to-Energy Combustion Processes : Method Development and Evaluation

    Författare :Eboh Francis Chinweuba; Simon Harvey; Högskolan i Borås; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid waste; exergy; entropy; higher heating value; improvement potential; waste-to-energy plant; efficiency improvement; cost evaluation; simulation; modelling; Resource Recovery; Resursåtervinning;

    Sammanfattning : is the energy recovery method. The electrical efficiency of this technology, however, is generally low when compared with other solid fuel-fired combustion plants as a result of low steam properties. Furthermore, there is lack of efficient methods to evaluate the performance of this system. LÄS MER

  4. 4. Heat demand profiles of buildings' energy conservation measures and their impact on renewable and resource efficient district heating systems

    Författare :Lukas Lundström; Erik Dahlquist; Fredrik Wallin; Björn Karlsson; Jan Akander; Sven Werner; Mälardalens högskola; []

    Sammanfattning : Increased energy performance of the building stock of European Union is seen as an important measure towards mitigating climate change, increasing resource utilisation efficiency and energy supply security. Whether to improve the supply-side, the demand-side or both is an open issue. LÄS MER

  5. 5. Waste-integrated biorefineries : A path towards efficient utilization of waste

    Författare :Chaudhary Awais Salman; Jinyue Yan; Eva Thorin; Mika Järvinen; Mälardalens högskola; []
